quad-core intel? xeon? processor 5300 series datasheet 9 introduction 1 introduction the quad-core intel? xeon? processor 53 00 series are 64-bit server/workstation processors utilizing four intel core? microa rchitecture cores. these processors are based on intel?s 65 nanometer process technology combining high performance with the power efficiencies of low-power intel core? microarchitecture cores. the quad-core intel? xeon? processor 5300 series consists of two die, each containing two processor cores. all processors maintain the tradition of compatibility with ia-32 software. some key features include on-die, 32 kb level 1 instruction data caches per core and 4 mb shared level 2 cache per die (8 mb total cache per processor) with advanced transfer cache architecture. the processor?s data prefetch logic speculatively fetches data to the l2 cache before an l1 cache requests occurs, resulting in reduced bus cycle penalties and improv ed performance. the 1333 mhz front side bus (fsb) is a quad-pumped bus running off a 333 mhz system clock, which results in 10.6 gbytes per second data transfer. th e 1066 mhz front side bus is based on a 266 mhz system clock for an 8.5 gbytes per se cond data transfer rate. the quad-core intel? xeon? processor x5300 series offe rs higher clock frequencies than the quad-core intel? xeon? processor e5300 series for platforms that are targeted for the performance optimized segment.. enhanced thermal and power management capabilities are implemented including thermal monitor 1 (tm1), thermal monitor 2 (tm2) and enhanced intel speedstep? technology. tm1 and tm2 provide efficient an d effective cooling in high temperature situations. enhanced intel speedstep? te chnology provides power management capabilities to servers and workstations. the quad-core intel? xeon? processor 5300 series features include advanced dynamic execution, enhanced floating po int and multi-media units, streaming simd extensions 2 (sse2) and streaming simd extensions 3 (sse3). advanced dynamic execution improves speculative execution and branch prediction internal to the processor. the floating point and multi-media units include 128-bit wide registers and a separate register for data movement. sse3 instructions provide highly efficient double- precision floating point, simd integer, and memory management operations. the quad-core intel? xeon? processor 5300 series supports intel? 64 architecture as an enhancement to intel's ia-32 architecture. this enhancement allows the processor to execute operating systems and ap plications written to take advantage of the 64-bit extension technology. further details on intel 64 architecture and its programming model can be found in the intel? 64 and ia-32 architecture software developer's manual . in addition, the quad-core intel? xeon? processor 5300 series supports the execute disable bit functionality. when used in conj unction with a supporting operating system, execute disable allows memory to be marked as executable or non executable. this feature can prevent some classes of viruses that exploit buffer overrun vulnerabilities and can thus help improve the overall security of the system. further details on execute disable can be found at: http://www3.intel.com/cd/ids/dev eloper/asmo-na/eng/149308.htm the quad-core intel? xeon? processor 5300 series supports intel? virtualization technology for hardware-assisted virtualization within the processor. intel virtualization technology is a set of hardware enhancements that can improve virtualization solutions. intel virtualization technology is used in conjunction with virtual machine
introduction 10 quad-core intel? xeon? processor 5300 series datasheet monitor software enabling multiple, independent software environments inside a single platform. further details on intel virtualization technology can be found at http://developer.intel.com/techno logy/virtualization/index.htm . the quad-core intel? xeon? processor 5300 se ries are intended for high performance server and workstation systems. the proce ssors support a dual independent bus (dib) architecture with one processor on each bus, up to two processor sockets in a system. the dib architecture provides improved perf ormance by allowing increased fsb speeds and bandwidth. the processors will be packaged in an fc-lga6 land grid array package with 771 lands for improved powe r delivery. it utilizes a surface mount lga771 socket that supports direct socket loading (dsl). quad-core intel? xeon? processor 5300 series based platforms implement independent core voltage (v cc ) power planes for each processor. fsb termination voltage (v tt ) is shared and must connect to all fsb agents. the processor core voltage utilizes power delivery guidelines specified by vrm/evrd 11.0 and its associated load line (see voltage regulator module (vrm) and enterprise voltage regulator-down (evrd) 11.0 design guidelines for further details). vrm/evrd 11.0 will support the power requirements of all frequencies of th e processors including flexible motherboard guidelines (fmb) (see section 2.13.1 ). refer to the appropriate platform design guidelines for implementation details. the quad-core intel? xeon? processor 5300 series support either 1333 or 1066 mhz front side bus operation. the fsb utilizes a split-transaction, deferred reply protocol and source-synchronous transfer (sst) of address and data to improve performance. the processor transfers data four times per bus clock (4x data transfer rate, as in agp 4x). along with the 4x data bus, the addr ess bus can deliver addresses two times per bus clock and is referred to as a ?double-clocked? or a 2x address bus. in addition, the request phase completes in one clock cycle. working together, the 4x data bus and 2x address bus provide a data bus bandwidth of up to 10.66 gbytes (1333 mhz) or 8.5 gbytes (1066 mhz) per second. the fsb is also used to deliver interrupts. signals on the fsb use assisted gunning transceiver logic (agtl+) level voltages. section 2.1 contains the electrical specifications of the fsb while implementation details are fully described in the appropriat e platform design guidelines (refer to section 1.3 ) . table 1-1. quad-core intel? xeon ? processor 5300 series features # of processor cores l1 cache (per core) l2 advanced transfer cache front side bus frequency package 4 32 kb instruction 32 kb data 4mb shared l2 cache per die 8mb total cache 1333 mhz 1066 mhz fc-lga6 771 lands
quad-core intel? xeon? processor 5300 series datasheet 11 introduction 1.1 terminology a ?#? symbol after a signal name refers to an active low signal, indicating a signal is in the asserted state when driven to a low level. for example, when reset# is low, a reset has been requested. conversely, when nmi is high, a nonmaskable interrupt has occurred. in the case of signals where the name does not imply an active state but describes part of a binary sequence (such as address or data ), the ?#? symbol implies that the signal is inverted. for example, d[3:0] = ?hlhl? refers to a hex ?a?, and d[3:0]# = ?lhlh? also refers to a hex ?a? (h= high logic level, l= low logic level). commonly used terms are explained here for clarification: ? quad-core intel? xeon? processor 5300 series ? intel 64-bit microprocessor intended for dual processor servers an d workstations. the quad-core intel? xeon? processor 5300 series is based on intel?s 65 nanometer process, in the fc-lga6 package with four processor cores. for this document, ?processor? is used as the generic term for the ?quad-core intel? xeon? processor 5300 series?. the term ?processors? and ?quad-core inte l? xeon? processor 5300 series? are inclusive of quad-core intel? xeon? processor e5300 series and quad-core intel? xeon? processor x5300 series. ? quad-core intel? xeon? processor e5300 series ? a mainstream performance version of the quad-core intel? xeon? processor e5300 series. for this document ?quad-core intel? xeon? processor e5300 series? is used to call out specifications that are unique to th e quad-core intel? xeon? processor e5300 series sku. ? quad-core intel? xeon? processor x5300 series ? an accelerated performance version of the quad-core in tel? xeon? processor x5300 series. for this document ?quad-core intel? xeon? processor x5300 series? is used to call out specifications that are unique to th e quad-core intel? xeon? processor x5300 series sku. ? fc-lga6 (flip chip land grid array) package ? the quad-core intel? xeon? processor 5300 series package is a land grid array, consisting of a processor core mounted on a pinless substrate with 771 la nds, and includes an integrated heat spreader (ihs). ? lga771 socket ? the quad-core intel? xeon? processor 5300 series interfaces to the baseboard through this surface mount, 771 land socket. see the lga771 socket design guidelines for details regarding this socket. ? processor core ? processor core with integrated l1 cache. l2 cache and system bus interface are shared between the two core s on the die. all ac timing and signal integrity specifications are at the pads of the processor die. ? fsb (front side bus) ? the electrical interface that connects the processor to the chipset. also referred to as the proce ssor system bus or the system bus. all memory and i/o transactions as well as interrupt messages pass between the processor and chipset over the fsb.

introduction 14 quad-core intel? xeon? processor 5300 series datasheet
quad-core intel? xeon? processor 5300 series datasheet 15 electrical specifications 2 electrical specifications 2.1 front side bus and gtlref most quad-core intel? xeon? processor 5300 series fsb signals use assisted gunning transceiver logic (agtl+) signalin g technology. this technology provides improved noise margins and reduced ringing through low voltage swings and controlled edge rates. agtl+ buffers are open-drain and require pull-up resistors to provide the high logic level and termination. agtl+ output buffers differ from gtl+ buffers with the addition of an active pmos pull-up transistor to ?assist? the pull-up resistors during the first clock of a low-to-high voltage transition. platforms implement a termination voltage level for agtl+ signals defined as v tt . because platforms implement separate power planes for each processor (and chipset), separate v cc and v tt supplies are necessary. this configuration allows for improved noise tolerance as processor frequency increases. speed enhancements to data and address buses have made signal integrity considerations and platform design methods even more critical than with previous processor families. design guidelines for the processor fsb are detailed in the appropriate platform design guidelines (refer to section 1.3 ). the agtl+ inputs require reference voltages (gtlref_data_mid, gtlref_data_end, gtlref_add_mid and gtlref_add_end) which are used by the receivers to determine if a signal is a logical 0 or a logical 1. gtlref_data_mid and gtlref_data_end are used for the 4x front side bus signaling group and gtlref_add_mid and gtlref_add_end are used for the 2x and common clock front side bus signaling groups. gtlref_data_mid, gtlref_data_end, gtlref_add_mid, and gtlref_add_end must be generated on the baseboard (see ta b l e 2 - 1 8 for gtlref_data_mid, gtlref_data_end, gtlref_add_mid and gtlref_add_end specifications). refer to th e applicable platform design guidelines for details. termination resistors (r tt ) for agtl+ signals are provided on the processor silicon and are terminated to v tt . the on-die termination resistors are always enabled on the processor to control reflections on the transmission line. intel chipsets also provide on-die termination, thus eliminat ing the need to terminate the bus on the baseboard for most agtl+ signals. some fsb signals do not include on-die termination (r tt ) and must be terminated on the baseboard. see ta b l e 2 - 7 and ta b l e 2 - 8 for details regarding these signals. the agtl+ bus depends on incident wave swit ching. therefore, timing calculations for agtl+ signals are based on flight time as opposed to capacitive deratings. analog signal simulation of the fsb, including tr ace lengths, is highly recommended when designing a system. contact your intel field representative to obtain the applicable signal integrity models , which includes buffer and package models.
electrical specifications 16 quad-core intel? xeon? processor 5300 series datasheet 2.2 power and ground lands for clean on-chip processor core power distribution, the processor has 223 v cc (power) and 267 v ss (ground) inputs. all v cc lands must be connected to the processor power plane, while all v ss lands must be connected to the system ground plane. the processor v cc lands must be supplied with the voltage determined by the processor v oltage id entification (vid) signals. see ta b l e 2 - 3 for vid definitions. twenty two lands are specified as v tt , which provide termination for the fsb and provides power to the i/o buffers. the platfo rm must implement a separate supply for these lands which meets the v tt specifications outlined in ta b l e 2 - 1 2 . 2.3 decoupling guidelines due to its large number of transistors and high internal clock speeds, the processor is capable of generating large average current swings between low and full power states. this may cause voltages on power planes to sag below their minimum values if bulk decoupling is not adequate. larger bulk storage (c bulk ), such as electrolytic capacitors, supply current during longer lasting chan ges in current demand by the component, such as coming out of an idle condition. si milarly, they act as a storage well for current when entering an idle condition from a running condition. care must be taken in the baseboard design to ensure that the voltag e provided to the processor remains within the specifications listed in ta b l e 2 - 1 2 . failure to do so can result in timing violations or reduced lifetime of the component. for furthe r information and guidelines, refer to the appropriate platform design guidelines. 2.3.1 v cc decoupling vcc regulator solutions need to provide bulk capacitance with a low effective series resistance (esr), and the baseboard designer must assure a low interconnect resistance from the regulator (evrd or vrm pins) to the lga771 socket. bulk decoupling must be provided on the basebo ard to handle large current swings. the power delivery solution must insure the voltage and current specifications are met (as defined in ta b l e 2 - 1 2 ). for further information regarding power delivery, decoupling and layout guidelines, refer to the a ppropriate platform design guidelines . 2.3.2 v tt decoupling bulk decoupling must be prov ided on the baseboard. decoupling solutions must be sized to meet the expected load. to insure optimal performance, various factors associated with the power delivery solution must be considered including regulator type, power plane and trace sizing, and component placement. a conservative decoupling solution consists of a combination of low esr bulk capacitors and high frequency ceramic capacitors. for furthe r information regarding power delivery, decoupling and layout guidelines, refer to th e appropriate platform design guidelines.
quad-core intel? xeon? processor 5300 series datasheet 17 electrical specifications 2.3.3 front side bus agtl+ decoupling the processor integrates signal termination on the die, as well as a portion of the required high frequency decoupling capacita nce on the processor package. however, additional high frequency capacitance must be added to the baseboard to properly decouple the return currents from the fsb. bulk decoupling must also be provided by the baseboard for proper agtl+ bus operation. decoupling guidelines are described in the appropriate platform design guidelines. 2.4 front side bus clock (bclk[1:0]) and processor clocking bclk[1:0] directly controls the fsb interface speed as well as the core frequency of the processor. as in previous processor generations, the processor core frequency is a multiple of the bclk[1:0] frequency. the pr ocessor bus ratio multiplier is set during manufacturing. the default setting is for th e maximum speed of the processor. it is possible to override this setti ng using software (see the intel? 64 and ia-32 architectures software developer?s manual ). this permits operation at lower frequencies than the processor?s tested frequency. the processor core frequency is configured during reset by using values stored internally during manufacturing. the stored value sets the highest bus fraction at which the particular processor can operate. if lower speeds are desired, the appropriate ratio can be configured via the clock_flex_max mo del specific register (msr). for details of operation at core frequencies lower than the maximum rated processor speed, refer to the intel? 64 and ia-32 architectures software developer?s manual. clock multiplying within the processor is pr ovided by the internal phase locked loop (pll), which requires a constant frequency bc lk[1:0] input, with exceptions for spread spectrum clocking. processor dc and ac sp ecifications for the bclk[1:0] inputs are provided in ta b l e 2 - 1 9 . these specifications must be met while also meeting signal integrity requirements as outlined in ta b l e 2 - 1 9 . the processor utilizes differential clocks. ta b l e 2 - 1 contains processor core frequency to fsb multipliers and their corresponding core frequencies.

quad-core intel? xeon? processor 5300 series datasheet 21 electrical specifications note: the ll_id[1:0] signals are used by the platform to select the correct loadline slope for the processor. note: the ms_id[1:0] signals are provided to indicate the market segment for the processor and may be used for future processor co mpatibility or for keying. 2.6 reserved, unused, or test signals all reserved signals must remain unconnected. connection of these signals to v cc , v tt , v ss , or to any other signal (including each other) can result in component malfunction or incompatibility with future processors. see section 4 for a land listing of the processor and the location of all reserved signals. for reliable operation, always connect unused inputs or bidirectional signals to an appropriate signal level. unused active high inputs, should be connected through a resistor to ground (v ss ). unused outputs can be left unconnected; however, this may interfere with some tap functions, comp licate debug probing, and prevent boundary scan testing. a resistor must be used when tying bidirectional signals to power or ground. when tying any signal to power or ground, a resistor will also allow for system testability. resistor values should be with in 20% of the impedance of the baseboard trace for fsb signals, unless otherwise noti ced in the appropriate platform design guidelines. for unused agtl+ input or i/o signals, use pull-up resistors of the same value as the on-die termination resistors (r tt ). for details see ta b l e 2 - 1 8 . tap, asynchronous gtl+ inputs, and asynchro nous gtl+ outputs do not include on-die termination. inputs and utilized outputs must be terminated on the baseboard. unused outputs may be terminated on the baseboard or left unconnected. note that leaving unused outputs unterminated may interfere with some tap functions, complicate debug probing, and prevent boundary scan testing. signal termination for these signal types is discussed in the appropriate platform design guidelines. for each processor socket, connect the te stin1 and testin2 signals together, then terminate the net with a 51 resistor to v tt . the testhi signals must be tied to the processor v tt using a matched resistor, where a matched resistor has a resistance value within 20% of the impedance of the board transmission line traces. for example, if the trace impedance is 50 , then a value between 40 and 60 is required. table 2-4. loadline selection truth table for ll_id[1:0] ll_id1 ll_id0 description 00reserved 0 1 dual-core intel? xeon? processor 5000 series dual-core intel? xeon? processor 5100 series 10reserved 1 1 all quad-core intel? xeon? processor 5300 series table 2-5. market segment select ion truth table for ms_id[1:0] ms_id1 ms_id0 description 0 0 dual-core intel? xeon? processor 5000 series 0 1 dual-core intel? xeon? processor 5100 series 1 0 all quad-core intel? xeon? processor 5300 series 11reserved
electrical specifications 22 quad-core intel? xeon? processor 5300 series datasheet the testhi signals may use individual pull-up resistors or be grouped together as detailed below. a matched resistor must be used for each group: ? testhi[1:0] - can be grouped together with a single pull-up to v tt ? testhi[7:2] - can be grouped together with a single pull-up to v tt ? testhi10 ? cannot be groupe d with other testhi signals ? testhi11 ? cannot be groupe d with other testhi signals 2.7 front side bus signal groups the fsb signals have been combined into groups by buffer type. agtl+ input signals have differential input buffers, which use gtlref_data_mid, gtlref_data_end, gtlref_add_mid, and gtlref_add_end as reference levels. in this document, the term ?agtl+ input? refers to the agtl+ input group as well as the agtl+ i/o group when receiving. similarly, ?agtl+ output? re fers to the agtl+ outp ut group as well as the agtl+ i/o group when driving. agtl+ asynchronous outputs can become active anytime and include an active pmos pull-up tran sistor to assist during the first clock of a low-to-high voltage transition. with the implementation of a source synchr onous data bus comes the need to specify two sets of timing parameters. one set is for common clock signals whose timings are specified with respect to ri sing edge of bclk0 (ads#, hit#, hitm#, etc.) and the second set is for the source synchronous sign als which are relative to their respective strobe lines (data and address) as well as ri sing edge of bclk0. asynchronous signals are still present (a20m#, ignne#, etc.) and can become active at any time during the clock cycle. ta b l e 2 - 6 identifies which signals are common clock, source synchronous and asynchronous. table 2-6. fsb signal groups (sheet 1 of 2) signal group type signals 1 agtl+ common clock input synchronous to bclk[1:0] bpri#, defer#, reset#, rs[2:0]#, rsp#, trdy#; agtl+ common clock output synchronous to bclk[1:0] bpm4#, bpm[2:1]#, bpmb[2:1]# agtl+ common clock i/o synchronous to bclk[1:0] ads#, ap[1:0]#, binit# 2 , bnr# 2 , bpm5#, bpm3#, bpm0#, bpmb3# , bpmb0#, br[1:0]#, dbsy#, dp[3:0]#, drdy#, hit# 2 , hitm# 2 , lock#, mcerr# 2 agtl+ source synchronous i/o synchronous to assoc. strobe agtl+ strobes i/o synchronous to bclk[1:0] adstb[1:0]#, dstbp[3:0]#, dstbn[3:0]# open drain output asynchronous ferr#/pbe#, ierr#, prochot#, thermtrip# signals associated strobe req[4:0]#,a[16:3]#, a[37:36]# 3 adstb0# a[35:17]# adstb1# d[15:0]#, dbi0# dstbp0#, dstbn0# d[31:16]#, dbi1# dstbp1#, dstbn1# d[47:32]#, dbi2# dstbp2#, dstbn2# d[63:48]#, dbi3# dstbp3#, dstbn3#

signal definitions 72 quad-core intel? xeon? processor 5300 series datasheet binit# i/o binit# (bus initialization) may be obse rved and driven by all processor fsb agents and if used, must connect the appropriate pins of all such agents. if the binit# driver is enabled during power on configuration, binit# is asserted to signal any bus condition that prevents re liable future operation. if binit# observation is enabled during power-on configuration (see section 7.1 ) and binit# is sampled asserted, symmetric ag ents reset their bus lock# activity and bus request arbitration state machines. the bus agents do not reset their i/o queue (ioq) and transaction tracking state machin es upon observation of binit# assertion. once the binit# assertion ha s been observed, the bus agen ts will re-arbitrate for the fsb and attempt completion of their bus queue and ioq entries. if binit# observation is disabled during power-on configuration, a priority agent may handle an assertion of binit# as appropriat e to the error handling architecture of the system. 3 bnr# i/o bnr# (block next request) is used to assert a bus stall by any bus agent who is unable to accept new bus transactions. during a bus stall, the current bus owner cannot issue any new transactions. since multiple agents might ne ed to request a bus stall at the same time, bnr# is a wired-or signal which must connect the appr opriate pins of all processor fsb agents. in order to avoid wired-or glitches associated with simultaneous edge transitions driven by multiple drivers, bnr# is acti vated on specific clock edges and sampled on specific clock edges. 3 bpm5# bpm4# bpm3# bpm[2:1]# bpm0# i/o o i/o o i/o bpm[5:0]# (breakpoint monitor) are breakp oint and performance monitor signals. they are outputs from the processor which indicate the status of breakpoints and programmable counters used for monitoring processor performance. bpm[5:0]# should connect the appropriate pins of all fsb agents. bpm4# provides prdy# (probe ready) func tionality for the tap port. prdy# is a processor output used by debug tools to determine processor debug readiness. bpm5# provides preq# (probe request) func tionality for the tap port. preq# is used by debug tools to request debug operation of the processors. bpm[5:4]# must be bussed to all bus agents . please refer to the appropriate platform design guidelines for mo re detailed information. 2 bpmb3# bpmb[2:1]# bpmb0# i/o o i/o bpmb[3:0]# (breakpoint monitor) are a second set of breakpoint and performance monitor signals. they are additional outpu ts from the processor which indicate the status of breakpoints and programmable counters used for monitoring processor performance. bpmb[3:0]# should connect the appropriate pins of all fsb agents. 2 bpri# i bpri# (bus priority request) is used to arbitrate for ownership of the processor fsb. it must connect the appropriate pins of all processor fsb agents. observing bpri# active (as asserted by the priority agent) causes all other agents to stop issuing new requests, unless such requests are part of an ongoing locked operation. the priority agent keeps bpri# asserted until all of its re quests are completed, then releases the bus by deasserting bpri#. 3 br[1:0]# i/o the br[1:0]# signals are sampled on th e active-to-inactive transition of reset#. the signal which the agent samples asserted determines its agent id. br0# drives the breq0# signal in the system and is used by the processor to request the bus. these signals do not have on-die termination and must be terminated. 3 bsel[2:0] o the bclk[1:0] frequency select signals bsel[2:0] are used to select the processor input clock frequency. ta b l e 2 - 2 defines the possible combin ations of the signals and the frequency associated with each combination. the required frequency is determined by the processors, chipset, and clock synthesizer. all fsb agents must operate at the same frequency. for more information about thes e signals, including termination recommendations, refer to the appropriate platform design guideline. comp[3:0] i comp[3:0] must be terminated to vss on the baseboard using precision resistors. these inputs configure the agtl+ drivers of the processor. refer to the appropriate platform design guidelines for implementation details. table 5-1. signal definitions (sheet 2 of 8) name type description notes
quad-core intel? xeon? processor 5300 series datasheet 73 signal definitions d[63:0]# i/o d[63:0]# (data) are the data signals. these signals provide a 64-bit data path between the processor fsb agents, and must connect the appropriate pins on all such agents. the data driver asserts drdy# to indicate a valid data transfer. d[63:0]# are quad-pumped signals, and wi ll thus be driven four times in a common clock period. d[63:0]# are la tched off the falling edge of both dstbp[3:0]# and dstbn[3:0]#. each group of 16 data signals correspond to a pair of one dstbp# and one ds tbn#. the following table shows the grouping of data signals to strobes and dbi#. furthermore, the dbi# sign als determine the polarity of the data signals. each group of 16 data signals corresp onds to one dbi# signal. when the dbi# signal is active, the correspon ding data group is inverted and therefore sampled active high. 3 dbi[3:0]# i/o dbi[3:0]# (data bus inversion) are source synchronous and indicate the polarity of the d[63:0]# signals. the dbi[3:0]# signals are activated when the data on the data bus is inverted. if more than half the data bits, within, within a 16-bit group, would have been asserted electronically low, the bus agent may invert the data bus signals for that particular sub-phase for that 16-bit group. 3 dbr# o dbr# is used only in systems where no debug port connector is implemented on the system board. dbr# is used by a debug port interposer so that an in-target probe can drive reset. if a debug port connector is implemented in the system, dbr# is a no- connect on the quad-core intel? xeon? processor 5300 series package. dbr# is not a processor signal. dbsy# i/o dbsy# (data bus busy) is asserted by the agent responsible for driving data on the processor fsb to indicate that the data bus is in use. the data bus is released after dbsy# is deasserted. this signal must connect the appropriate pins on all processor fsb agents. 3 defer# i defer# is asserted by an agent to indi cate that a transaction cannot be guaranteed in-order completion. assertion of defe r# is normally the responsibility of the addressed memory or i/o agent. this signal must connect the appropriate pins of all processor fsb agents. 3 dp[3:0]# i/o dp[3:0]# (data parity) provide parity protection for the d[63:0]# signals. they are driven by the agent responsible for dr iving d[63:0]#, and must connect the appropriate pins of all processor fsb agents. 3 drdy# i/o drdy# (data ready) is asserted by the data driver on each data transfer, indicating valid data on the data bus. in a multi-common clock data transfer, drdy# may be deasserted to insert idle cl ocks. this signal must connect the appropriate pins of all processor fsb agents. 3 table 5-1. signal definitions (sheet 3 of 8) name type description notes data group dstbn#/ dstbp# dbi# d[15:0]# 0 0 d[31:16]# 1 1 d[47:32]# 2 2 d[63:48]# 3 3 dbi[3:0] assignment to data bus bus signal data bus signals dbi0# d[15:0]# dbi1# d[31:16]# dbi2# d[47:32]# dbi3# d[63:48]#

quad-core intel? xeon? processor 5300 series datasheet 75 signal definitions ignne# i ignne# (ignore numeric error) is asserted to force the processor to ignore a numeric error and continue to execute noncontrol floating-point instructions. if ignne# is deasserted, the processor generates an exception on a noncontrol floating-point instruction if a previous floating-point instruction caused an error. ignne# has no effect when the ne bit in control register 0 (cr0) is set. ignne# is an asynchronous signal. however, to ensure recognition of this signal following an i/o write instruction, it must be valid along with the trdy# assertion of the corresponding i/o write bus transaction. 2 init# i init# (initialization), when asserted, re sets integer registers inside all processors without affecting their internal caches or fl oating-point registers. each processor then begins execution at the power-on reset vector configured during power-on configuration. the processor continues to handle snoop requests during init# assertion. init# is an asynchronous signal and must connect the appropriate pins of all processor fsb agents. 2 lint[1:0] i lint[1:0] (local apic interrupt) must connect the appropriate pins of all fsb agents. when the apic functionality is disabled , the lint0/intr signal becomes intr, a maskable interrupt request signal, and lint1/nmi becomes nmi, a nonmaskable interrupt. intr and nmi are backward compatible with the signals of those names on the pentium ? processor. both signals are asynchronous. these signals must be software configured via bios programming of the apic register space to be used either as nmi/intr or lint[1:0]. because the apic is enabled by default after reset, operation of these pins as lint[1:0] is the default configuration. 2 ll_id[1:0] o the ll_id[1:0] signals are used to select the correct loadline slope for the processor. these signals are not connected to the processor die. a logic 0 is pulled to ground and a logic 1 is a no-connect on the quad-core intel? xeon? processor 5300 series package. lock# i/o lock# indicates to the system that a transaction must occur atomically. this signal must connect the appropriate pins of all pr ocessor fsb agents. for a locked sequence of transactions, lock# is asserted from the beginning of the first transaction to the end of the last transaction. when the priority agent asserts bpri# to arbitrate for ownership of the processor fsb, it will wait until it observes lock# de asserted. this enables symmetric agents to retain ownership of the processor fsb throughout the bus locked operation and ensure the atomicity of lock. 3 mcerr# i/o mcerr# (machine check error) is asse rted to indicate an unrecoverable error without a bus protocol violation. it may be driven by all processor fsb agents. mcerr# assertion conditions are configurable at a system level. assertion options are defined by the following options: ? enabled or disabled. ? asserted, if configured, for internal errors along with ierr#. ? asserted, if configured, by the request initiator of a bus transaction after it observes an error. ? asserted by any bus agent when it ob serves an error in a bus transaction. for more details regarding machine check architecture, refer to the intel? 64 and ia-32 intel? architecture software de veloper?s manual, volume 3: system programming guide . ms_id[1:0] o these signals are provided to indica te the market segment for the processor and may be used for future proces sor compatibility or for keying. these signals are not connected to the processor die. a logic 0 is pulled to ground and a logic 1 is a no- connect on the quad-core intel? xeon? processor 5300 series package. peci i/o peci is a proprietary one-wire bus interface that provides a communication channel between intel processor and chipset compon ents to external thermal monitoring devices. see section 6.3, ?platform environment control interface (peci)? for more on the peci interface. prochot# o prochot# (processor hot) will go active when the processor?s temperature monitoring sensor detects that the processor has reached its maximum safe operating temperature. this indicates that the thermal control circuit (tcc) has been activated, if enabled. the tcc will remain active until shortl y after the processor deasserts prochot#. see section 6.2.5 for more details. table 5-1. signal definitions (sheet 5 of 8) name type description notes
signal definitions 76 quad-core intel? xeon? processor 5300 series datasheet pwrgood i pwrgood (power good) is an input. the processor requires this signal to be a clean indication that all processor clocks and power supplies are stab le and within their specifications. ?clean? implies that the signal will remain low (capable of sinking leakage current), without glitches, from the time that the power supplies are turned on until they come within specification. the signal must then transition monotonically to a high state. pwrgood can be driven inactive at any time, but clocks and power must again be stable before a subsequent rising edge of pwrgood. it must also meet the minimum pulse width specification in ta b l e 2 - 1 7 , and be followed by a 1- 10 ms reset# pulse. the pwrgood signal must be supplied to the processor; it is used to protect internal circuits against voltage sequencing issues. it should be driven high throughout boundary scan operation. 2 req[4:0]# i/o req[4:0]# (request command) must connect the appropriate pins of all processor fsb agents. they are asserted by the current bus owner to define the currently active transaction type. these signals are source synchronous to adstb[1:0]#. refer to the ap[1:0]# signal descripti on for details on parity checking of these signals. 3 reset# i asserting the reset# si gnal resets all processors to known states and invalidates their internal caches without writing back any of their contents. for a power-on reset, reset# must stay active for at least 1 ms after v cc and bclk have reached their proper specifications. on observing active reset#, all fsb agents will deassert their outputs within two clocks. reset# must not be kept asserted for more than 10 ms while pwrgood is asserted. a number of bus signals are sampled at the active-to-inactive transition of reset# for power-on configuration. these configuration options are described in the section 7.1 . this signal does not have on-die terminat ion and must be terminated on the system board. 3 rs[2:0]# i rs[2:0]# (response status) are driven by the response agent (the agent responsible for completion of the current transaction), and must connect the appropriate pins of all processor fsb agents. 3 rsp# i rsp# (response parity) is driven by the response agent (the agent responsible for completion of the current transaction) duri ng assertion of rs[2:0]#, the signals for which rsp# provides parity protection. it must connect to the appropriate pins of all processor fsb agents. a correct parity signal is high if an even number of covered signals are low and low if an odd number of covered signals are low. while rs[2:0]# = 000, rsp# is also high, since this indicates it is not being driven by any agent guaranteeing correct parity. 3 sktocc# o sktocc# (socket occupied) will be pulled to ground by the processor to indicate that the processor is present. there is no connection to the processor silicon for this signal. smi# i smi# (system management interrupt) is asserted asynchronously by system logic. on accepting a system management interrupt, processors save the current state and enter system management mode (smm). an smi acknowledge transaction is issued, and the processor begins program execution from the smm handler. if smi# is asserted during the deassertio n of reset# the processor will tri-state its outputs. see section 7.1 . 2 stpclk# i stpclk# (stop clock), when asserted, causes processors to enter a low power stop- grant state. the processor issues a stop-grant acknowledge transaction, and stops providing internal clock signals to all processor core units except the fsb and apic units. the processor continues to snoop bus transactions and service interrupts while in stop-grant state. when stpclk# is deasserted, the processor restarts its internal clock to all units and resumes execution. the assertion of stpclk# has no effect on the bus clock; stpclk# is an asynchronous input. 2 tck i tck (test clock) provides the clock input for the processor test bus (also known as the test access port). tdi i tdi (test data in) transfers serial test data into the processor. tdi provides the serial input needed for jtag specification support. tdo o tdo (test data out) transfers serial test data out of the processor. tdo provides the serial output needed for jtag specification support. table 5-1. signal definitions (sheet 6 of 8) name type description notes

quad-core intel? xeon? processor 5300 series datasheet 79 thermal specifications 6 thermal specifications 6.1 package thermal specifications the quad-core intel? xeon? processor 5300 series requires a thermal solution to maintain temperatures within its operating limits. any attempt to operate the processor outside these operating limits may result in permanent damage to the processor and potentially other components within the sy stem. as processor technology changes, thermal management becomes increasingly crucial when building computer systems. maintaining the proper thermal environmen t is key to reliable, long-term system operation. a complete solution includes both compon ent and system level thermal management features. component level thermal solutions can include active or passive heatsinks attached to the processor integrated heat spreader (ihs). typical system level thermal solutions may consist of system fans combined with ducting and venting. this section provides data necessary for de veloping a complete thermal solution. for more information on designing a component level thermal solution, refer to the quad-core intel? xeon? processor 5300 series thermal/mechanical design guidelines . note: the boxed processor will ship with a component thermal solution. refer to section 8 for details on the boxed processor. 6.1.1 thermal specifications to allow the optimal operation and long-term reliability of intel processor-based systems, the processor must remain within the minimum and maximum case temperature (t case ) specifications as defined by the applicable thermal profile (see ta b l e 6 - 1 and figure 6-1 for quad-core intel? xeon? processor e5300 series and ta b l e 6 - 3 and figure 6-2 for quad-core intel? xeon? processor x5300 series). thermal solutions not designed to provide this level of thermal capability may affect the long-term reliability of the processor and system. for more details on thermal solution design, please refer to the quad-core intel? xeon? processor 5300 series thermal/ mechanical design guidelines . the quad-core intel? xeon? processor 5300 series implement a methodology for managing processor temperatures which is intended to support acoustic noise reduction through fan speed control and to a ssure processor reliability. selection of the appropriate fan speed is based on the relative temperature data reported by the processor?s platform environment control interface (peci) bus as described in section 6.3 . the temperature reported over peci is always a negative value and represents a delta below the onset of thermal control circuit (tcc) activation, as indicated by prochot# (see section 6.2 , processor thermal features). systems that implement fan speed control must be designed to use this data. systems that do not alter the fan speed only need to guarantee the case temperature meets the thermal profile specifications. the quad-core intel? xeon? processor e5300 series (see figure 6-1 ; ta b l e 6 - 2 ) supports a single thermal profile. for these pr ocessors, it is expected that the thermal control circuit (tcc) would only be activated for very brief periods of time when
thermal specifications 80 quad-core intel? xeon? processor 5300 series datasheet running the most power-intensive applications. refer to the quad-core intel? xeon? processor 5300 series thermal/mechanical design guidelines for details on system thermal solution design, thermal profiles and environmental considerations. for the quad-core intel? xeon? processo r x5300 series, intel has developed two thermal profiles, either of which can be im plemented. both ensure adherence to intel reliability requirements. thermal profile a (see figure 6-2 ; ta b l e 6 - 4 ) is representative of a volumetrically unconstrained thermal solution (that is, industry enabled 2u heatsink). in this scenario, it is expected that the thermal control circuit (tcc) would only be activated for very brief periods of time when running the most power intensive applications. thermal profile b (see figure 6-2 ; ta b l e 6 - 5 ) is indicative of a constrained thermal environment (that is, 1u form factor). because of the reduced cooling capability represented by this thermal soluti on, the probability of tcc activation and performance loss is increased. additionally, utilization of a thermal solution that does not meet thermal profile b will violate the thermal specifications and may result in permanent damage to the processor. refer to the quad-core intel? xeon? processor 5300 series thermal/mechanical design guidelines for details on system thermal solution design, thermal profiles and environmental considerations. the upper point of the thermal profile consis ts of the thermal design power (tdp) and the associated t case value. it should be noted that the upper point associated with the quad-core intel? xeon? processor x5300 se ries thermal profile b (x = tdp and y = t case_max_b @ tdp) represents a thermal solution design point. in actuality the processor case temperature will not reach this value due to tcc activation (see figure 6-2 for quad-core intel? xeon? processo r x5300 series). the lower point of the thermal profile consists of x = p _profile_min and y = t case_max @ p _profile_min . p _profile_min is defined as the processor power at which t case , calculated from the thermal profile, is equal to 50c. analysis indicates that real applications are unlikely to cause the processor to consume maximum power dissipation for sustained time periods. intel recommends that complete thermal solution designs target the thermal design power (tdp), instead of the maximum processor power consumption. the thermal monitor feature is intended to help protect the processor in the ev ent that an application exceeds the tdp recommendation for a sustained time period. fo r more details on this feature, refer to section 6.2 . to ensure maximum flexibility for fu ture requirements, systems should be designed to the flexible motherboard (fmb) guidelines, even if a processor with lower power dissipation is currently planned. thermal monitor 1 and thermal monitor 2 feature must be enabled for the processor to remain within its specifications. notes: 1. these values are specified at v cc_max for all processor frequencies. syst ems must be designed to ensure the processor is not to be subjected to any static v cc and i cc combination wherein v cc exceeds v cc_max at specified i cc . please refer to the loadline specifications in section 2 . 2. maximum power is the highest power the processor will dissipate, regardless of its vid. maximum power is measured at maximum t case . 3. thermal design power (tdp) should be used for proc essor thermal solution design targets. tdp is not the maximum power that the processor can diss ipate. tdp is measured at maximum t case . 4. these specifications are based on initial silicon characterization. thes e specifications may be further updated as more characterization data becomes available. 5. power specifications are defined at all vids found in ta b l e 2 - 3 . the quad-core intel? xeon? processor e5300 series may be ship ped under multiple vids for each frequency. table 6-1. quad-core intel? xeon? proce ssor e5300 series thermal specifications core frequency thermal design power (w) minimum t case (c) maximum t case (c) notes launch to fmb 80 5 see figure 6-1 ; ta b l e 6 - 2 1, 2, 3, 4, 5, 6

quad-core intel? xeon? processor 5300 series datasheet 85 thermal specifications configurable and is not software visible. bus traffic is snooped in the normal manner, and interrupt requests are latched (and servic ed during the time that the clocks are on) while the tcc is active. when the tm1 is enabled, and a high temperature situation exists (that is, tcc is active), the clocks will be modulated by alternately turning off and on at a duty cycle specific to the processor (typically 30 - 50%). cycle times are processor speed dependent and will decrease as processor core frequencies increase. a small amount of hysteresis has been included to prevent rapid active/inactive transitions of the tcc when the processor temperature is near its maximum operating temperature. once the temperature has dropped below the maximum operating temperature, and the hysteresis timer has expired, the tcc goes inactive and clock modulation ceases. with thermal solutions designed to the quad-core intel? xe on? processor e5300 series thermal profile, or quad-core intel? xeon? processor x5300 series thermal profile a it is anticipated that the tcc would only be activated for very short periods of time when running the most power intensiv e applications. the pr ocessor performance impact due to these brief periods of tcc activation is expected to be so minor that it would be immeasurable. a thermal solution that is designed to quad-core intel? xeon? processor x5300 series thermal prof ile b may cause a noticeable performance loss due to increased tcc activation. thermal solutions that exceed thermal profile b will exceed the maximum temperature specific ation and affect the long-term reliability of the processor. in addition, a thermal solution that is significantly under designed may not be capable of cooling the processor even when the tcc is active continuously refer to the quad-core intel? xeon? processor 5300 series thermal/mechanical design guidelines for information on designing a thermal solution. the duty cycle for the tcc, when activate d by the tm1, is factory configured and cannot be modified. the tm1 does not require any additional hardware, software drivers, or interrupt handling routines. 6.2.3 thermal monitor 2 the quad-core intel? xeon? processor 5300 series adds support for an enhanced thermal monitor capability known as thermal monitor 2 (tm2). this mechanism provides an efficient means for limiting th e processor temperature by reducing the power consumption within the processor. tm2 requires support for dynamic vid transitions in the platform. when tm2 is enabled, and a high temperature situation is detected, the thermal control circuit (tcc) will be activated for all processor cores. the tcc causes the processor to adjust its operating frequency (via the bus multiplier) and input voltage (via the vid signals). this combination of reduced frequency and vid results in a reduction to the processor power consumption. a processor enabled for tm2 includes two operat ing points, each consisting of a specific operating frequency and voltage, which is id entical for both processor dies. the first operating point represents the normal operat ing condition for the processor. under this condition, the core-frequency-to-system-bus multiplier utilized by the processor is that contained in the clock_flex_max msr and the vid that is specified in ta b l e 2 - 3 . the second operating point consists of both a lower operating frequency and voltage. the lowest operating frequency is determined by the lowest supported bus ratio (1/6 for the quad-core intel? xeon? processor 5300 series). when the tcc is activated, the processor automatically transitions to the new frequency. this transition occurs rapidly, on the order of 5 s. during the freq uency transition, the processor is unable to
thermal specifications 86 quad-core intel? xeon? processor 5300 series datasheet service any bus requests, and consequently, all bus traffic is blocked. edge-triggered interrupts will be latched and kept pending until the processor resumes operation at the new frequency. once the new operating frequency is engaged, the processor will transition to the new core operating voltage by issuing a new vid code to the voltage regulator. the voltage regulator must support dynamic vid steps in order to support thermal monitor 2. during the voltage change, it will be necessary to transition through multiple vid codes to reach the target operating voltage. each step will be one vid table entry (see ta b l e 2 - 3 ). the processor continues to execute instructions during the voltage transition. operation at the lower voltage reduces the power consumption of the processor. a small amount of hysteresis has been in cluded to prevent rapid active/inactive transitions of the tcc when the processor temperature is near its maximum operating temperature. once the temperature has dropped below the maximum operating temperature, and the hysteresis timer has expired, the operating frequency and voltage transition back to the normal system operating point. transition of the vid code will occur first, in order to insure proper operation once the processor reaches its normal operating frequency. refer to figure 6-4 for an illustration of this ordering. the prochot# signal is asserted when a high temperature situation is detected, regardless of whether tm1 or tm2 is enabled. 6.2.4 on-demand mode the processor provides an auxiliary mechanism that allows system software to force the processor to reduce its power consumptio n. this mechanism is referred to as ?on- demand? mode and is distinct from the thermal monitor 1 and thermal monitor 2 features. on-demand mode is intended as a means to reduce system level power consumption. systems utilizing the quad-core intel? xeon? processor 5300 series must not rely on software usage of this me chanism to limit the processor temperature. if bit 4 of the ia32_clock_modulation ms r is set to a ?1?, the processor will immediately reduce its power consumption via modulation (starting and stopping) of the internal core clock, independent of the processor temperature. when using on- demand mode, the duty cycle of the clock mo dulation is programmable via bits 3:1 of the same ia32_clock_modulation msr. in on-demand mode, the duty cycle can figure 6-4. thermal monitor 2 frequency and voltage ordering vcc temperature v nom frequency time f tm2 f max t tm2 v tm2 t(hysterisis) vcc temperature v nom frequency time f tm2 f max t tm2 v tm2 t(hysterisis)

thermal specifications 88 quad-core intel? xeon? processor 5300 series datasheet 6.2.7 thermtrip# signal regardless of whether or not tm1 or tm2 is enabled, in the event of a catastrophic cooling failure, the processor will automatically shut down when the silicon has reached an elevated temperature (refer to the thermtrip# definition in ta b l e 5 - 1 ). at this point, the fsb signal thermtrip# will go active and stay active as described in ta b l e 5 - 1 . thermtrip# activation is independent of processor activity and does not generate any bus cycles. intel also recommends the removal of v tt . 6.3 platform environment control interface (peci) 6.3.1 introduction peci offers an interface for thermal mo nitoring of intel processor and chipset components. it uses a single wire, thus alleviating routing congestion issues. figure 6-5 shows an example of the peci topology in a system with quad-core intel? xeon? processor 5300 series. peci uses crc checking on the host side to ensure reliable transfers between the host and client devices. also, data transfer speeds across the peci interface are negotiable within a wide range (2 kbps to 2 mbps). the peci interface on quad-core intel? xeon? processor 5300 series is disabled by default and must be enabled through bios. more information on this can be found in the intel? 64 and ia-32 architecture software developer?s manual . 6.3.1.1 t control and tcc activation on peci-based systems fan speed control solutions based on peci utilize a t control value stored in the processor ia32_temperature_target msr. this msr uses the same offset temperature format as peci, though it contains no sign bit. thermal management devices should infer the t control value as negative. thermal management algorithms should utilize the relative temperature value delivered over peci in conjunction with the msr value to control or optimize fan speeds. figure 6-6 shows a conceptual fan control diagram using peci temperatures. figure 6-5. peci topology peci host c ontroller domain0 0 x 3 0 domain1 0 x 3 0 domain0 0 x 3 1 domain1 0 x 3 1 quad-core intel? xeon? processor 5300 series (socket 0) quad-core intel? xeon? processor 5300 series (socket 1) g5 g5
quad-core intel? xeon? processor 5300 series datasheet 89 thermal specifications 6.3.1.2 processor thermal data sample rate and filtering the dts provides an improved capability to monitor device hot spots, which inherently leads to more varying temperature readings over short time intervals. the dts sample interval range can be modified, and a data f iltering algorithm can be activated to help moderate this. the dts sample interval range is 82 ms (default) to 20 ms (max). this value can be set in bios. to reduce the sample rate requirements on peci and improve thermal data stability vs. time the processor dts also implements an averaging algorithm that filters the incoming data. this is an alpha-beta filter with coefficients of 0.5, and is expressed mathematically as: current_filtered_tem p = (previous_filtered_temp / 2) + (new_sensor_temp / 2). this filtering algorith m is fixed and cannot be changed. it is on by default and can be turned off in bios. host controllers should utilize the min/max sample times to determine the appropriate sample rate based on the controller's fan control algorithm and targeted response rate. the key items to take into account when settling on a fan control algorithm are the dts sample rate, whether the temperature filter is enabled, how often the peci host will poll the processor for temperature data, and the rate at which fan speed is changed. depending on the designer?s specific requir ements the dts sample rate and alpha-beta filter may have no effect on the fan control algorithm. 6.3.2 peci specifications 6.3.2.1 peci device address the peci device address for socket 0 is 0x30 and socket 1 is 0x31. please note that each address also supports two do mains (domain 0 and domain 1). 6.3.2.2 peci fault handling requirements peci is largely a fault tolerant interface, including noise immunity and error checking improvements over other compatible industry standard interfaces. the peci client is as reliable as the device that it is embedded within, and thus given operating conditions figure 6-6. conceptual fan control diagram for a peci-based platform fan speed (rpm) (not intended to depict actual implementation) max min temperature peci = -10 peci = -20 tcc activation temperature t control setting peci = 0 fan speed (rpm) (not intended to depict actual implementation) max min temperature peci = -10 peci = -20 tcc activation temperature t control setting peci = 0
thermal specifications 90 quad-core intel? xeon? processor 5300 series datasheet that fall under the specification, the peci c lient will always respond to requests and the protocol itself can be relied upon to detect any transmission failures. there are, however, certain scenarios where peci is known to be unresponsive. prior to a power on reset# and during rese t# assertion, peci is not guaranteed to provide reliable thermal data. system designs should implement a default power-on condition that ensures proper processor operation during the time frame when reliable data is not available via peci. to protect platforms from potential operational or safety issues due to an abnormal condition on peci, the peci host controller should take action to protect the system from possible damage. it is recommended that the peci host controller take appropriate action to protect the client proc essor device if valid temperature readings have not been obtained in response to three consecutive gettemp()s or for a one second time interval. the peci host controller may also implement an alert to software in the event of a critical or continuous fault condition. 6.3.2.3 peci gettemp0() and ge ttemp1() error code support the error codes supported for the processor gettemp0() and gettemp1() command are listed in ta b l e 6 - 6 below: table 6-6. gettemp0() and gettemp1() error codes error code description 0x8000 general sensor error 0x8002 sensor is operational, but has detected a temperature below its operational range (underflow).

quad-core intel? xeon? processor 5300 series datasheet 95 features 7.2.4.2 extended halt snoop state the extended halt snoop state is the default snoop state when the extended halt state is enabled via the bios. the processor will remain in the lower bus to core frequency ratio and vid operating po int of the extended halt state. while in the extended halt snoop state, sn oops and interrupt transactions are handled the same way as in the halt snoop state. afte r the snoop is serviced or the interrupt is latched, the processor will return to the extended halt state. 7.3 enhanced intel speedstep? technology quad-core intel? xeon? processor 5300 series support enhanced intel speedstep? technology. this technology enables the processor to switch between multiple frequency and voltage points, which results in platform power savings. enhanced intel speedstep technology requires support for dynamic vid transitions in the platform. switching between voltage/frequency states is software controlled. for more configuration details also refer to the intel? 64 and ia-32 architecture software developer?s manual . note: not all quad-core intel? xeon? processor 5300 series are capable of supporting enhanced intel speedstep technology. more details on which processor frequencies will support this feature will be provid ed in future releases of the quad-core intel? xeon? processor 5300 series specification update when available. enhanced intel speedstep technology creates processor performance states (p-states) or voltage/frequency operating points. p-stat es are lower power capability states within the normal state as shown in figure 7-1 . enhanced intel speedstep technology enables real-time dynamic switching between frequency and voltage points. it alters the performance of the processor by changi ng the bus to core frequency ratio and voltage. this allows the processor to run at different core frequencies and voltages to best serve the performance and power requir ements of the proce ssor and system. the quad-core intel? xeon? processor 5300 series have hardware logic that coordinates the requested voltage (vid) between the proc essor cores. the highest voltage that is requested from the four processor cores is selected for that processor package. note that the front side bus is not altered; only the internal core frequency is changed. in order to run at reduced power consumption, the voltage is altered in step with the bus ratio. the following are key features of enhanced intel speedstep technology: ? multiple voltage/frequency operating points provide optimal performance at reduced power consumption. ? voltage/frequency selection is software controlled by writing to processor msr?s (model specific registers), thus eliminating chipset dependency. ? if the target frequency is higher than the current frequency, v cc is incremented in steps (+12.5 mv) by placing a new value on the vid signals and the processor shifts to the new frequency. note that the top frequency for the processor can not be exceeded. ? if the target frequency is lower than the current frequency, the processor shifts to the new frequency and v cc is then decremented in steps (-12.5 mv) by changing the target vid through the vid signals. refer to the intel? 64 and ia-32 architecture software developer?s manual for specific information to enable and configure enhanc ed intel speedstep technology in bios.

quad-core intel? xeon? processor 5300 series datasheet 107 boxed processor specifications 8.2.2 boxed processo r heat sink weight 8.2.2.1 thermal solution weight the 1u passive/3u+ active combination heat sink solution and the 2u passive heat sink solution will not exceed a mass of 1050 grams. note that this is per processor, a dual processor system will have up to 2100 grams total mass in the heat sinks. this large mass will require a minimum chassis stiffness to be met in order to withstand force during shock and vibration. see section 3 for details on the processor weight. 8.2.3 boxed processor retent ion mechanism and heat sink support (cek) baseboards and chassis designed for use by a system integrator should include holes that are in proper alignment with each other to support the boxed processor. refer to the server system infrastructure specification (ssi-eeb 3.6, teb 2.1 or ceb 1.1). these specification can be found at: http://www.ssiforum.org. figure 8-3 illustrates the common enabling kit (c ek) retention solution. the cek is designed to extend air-cooling capability th rough the use of larger heat sinks with minimal airflow blockage and bypass. cek retention mechanisms can allow the use of much heavier heat sink masses compared to legacy limits by using a load path directly attached to the chassis pan. the cek spring on the secondary side of the baseboard provides the necessary compressive load for the thermal interface material. the baseboard is intended to be isolated such that the dynamic loads from the heat sink are transferred to the chassis pan via the stif f screws and standoffs. the retention scheme reduces the risk of package pullout and solder joint failures. all components of the cek heat sink solution will be captive to the heat sink and will only require a phillips screwdriver to attach to the chassis pan. when installing the cek, the cek screws should be tightened un til they will no longer turn easily. this should represent approximately 6-8 inch-p ounds of torque. more than that may damage the retention mechanism components. 8.3 electrical requirements 8.3.1 fan power supply (active cek) the 4-pin pwm controlled active thermal solution is being offered to help provide better control over pedestal chassis acoustics. this is achieved though more accurate measurement of processor die temperature through the processor?s digital thermal sensors. fan rpm is modulated through the use of an asic located on the baseboard, that sends out a pwm control signal to the 4th pin of the connector labeled as control. this thermal solution requires a constant + 12 v supplied to pin 2 of the active thermal solution and does not support variable voltage control or 3-pin pwm control. see ta b l e 8 - 2 for details on the 4-pin active heat sink solution connectors. if the 4-pin active fan heat sink solution is connected to an older 3-pin baseboard cpu fan header it will default back to a thermistor controlled mode, allowing compatibility with legacy 3-wire designs. when operatin g in thermistor controlled mode, fan rpm is automatically varied based on the tinlet temperature measured by a thermistor located at the fan inlet of the heat sink solution.
boxed processor specifications 108 quad-core intel? xeon? processor 5300 series datasheet the fan power header on the baseboard must be positioned to allow the fan heat sink power cable to reach it. the fan power head er identification and location must be documented in the suppliers platform documentation, or on the baseboard itself. the baseboard fan power header should be posi tioned within 177.8 mm [7 in.] from the center of the processor socket. note: 1. system board should pull this pin up to vcc with a resistor note: system board should provide an open drain / open collector for pin 4. fan will pull this pin up to a specific voltage (5.25v max). 8.3.2 boxed processor cooling requirements as previously stated the boxed processor will be available in two product configurations. each configuration will requ ire unique design considerations. meeting the processor?s temperature specifications is also the function of the thermal design of the entire system, and ultimately the resp onsibility of the system integrator. the processor temperature specifications are found in section 6 of this document. table 8-1. pwm fan frequency specificatio ns for 4-pin active cek thermal solution description min frequency nominal frequency max frequency unit pwm control frequency range 21,000 25,000 28,000 hz table 8-2. fan specifications for 4-pin active cek thermal solution description1 min typ steady max steady max startup unit +12 v: 12 volt fan power supply 10.8 12 12 13.2 v ic: fan current draw n/a 1 1.25 1.5 a sense: sense frequency 2 2 2 2 pulses per fan revolution figure 8-11. fan cable connector pin ou t for 4-pin active cek thermal solution table 8-3. fan cable connector pin out for 4-pin active cek thermal solution pin number signal color 1 ground black 2 power: (+12 v) yellow 3 sense: 2 pulses per revolution green 4 control: 21 khz-28 khz blue
quad-core intel? xeon? processor 5300 series datasheet 109 boxed processor specifications 8.3.2.1 1u passive/3u+ active combinat ion heat sink solution (1u rack passive) in the 1u configuration it is assumed that a chassis duct will be implemented to provide a minimum airflow of 15 cfm at 0.38 in. h 2 o (25.5 m 3 /hr at 94.6 pa) of flow impedance. the duct should be carefully designed to minimize the airflow bypass around the heatsink. it is assumed that a 40 c tla is met. this requires a superior chassis design to limit the t rise at or below 5c with an external ambient temperature of 35 c. following these guidelines will allow the designer to meet quad-core intel? xeon? processor x5300 series thermal profile and conform to the thermal requirements of the processor. 8.3.2.2 1u passive/3u+ active combinat ion heat sink solution (pedestal active) the active configuration of the combination solution is designed to help pedestal chassis users to meet the thermal processor requirements without the use of chassis ducting. it may be still be necessary to impl ement some form of chassis air guide or air duct to meet the t la temperature of 40 c depending on the pedestal chassis layout. also, while the active thermal solution design will mechanically fit into a 2u volumetric, it may not provide adequate airflow. this is due to the requirement of additional space at the top of the thermal solution to allow sufficient airflow into the heat sink fan. use of the active configuration in a 2u rackmount chassis is not recommended. it is recommended that the ambient air temperature outside of the chassis be kept at or below 35c. the air passing directly over the processor thermal solution should not be preheated by other system componen ts. meeting the processor?s temperature specification is the responsibility of the system integrator. 8.3.2.3 2u passive heat sink solu tion (2u+ rack or pedestal) in the 2u+ passive configuration it is assume d that a chassis duct will be implemented to provide a minimum airflow of 27 cfm at 0.182 in. h 2 o (45.9 m 3 /hr at 45.3 pa) of flow impedance. the duct should be carefu lly designed to minimize the airflow bypass around the heatsink. the t la temperature of 40 c should be met. this may require the use of superior design techniques to keep t rise at or below 5c based on an ambient external temperature of 35c. 8.4 boxed processor contents a direct chassis attach method must be us ed to avoid problems related to shock and vibration, due to the weight of the thermal so lution required to c ool the processor. the board must not bend beyond specificatio n in order to avoid damage. the boxed processor contains the components necessary to solve both issues. the boxed processor will include the following items: ? quad-core intel? xeon? processor 5300 series ? unattached heat sink solution ? four screws, four springs, and four heat si nk standoffs (all captive to the heat sink) ? foam air bypass pad and skirt (included with 1u passive/3u+ active solution) ? thermal interface material (pre-applied on heat sink) ? installation and warranty manual ?intel inside logo

quad-core intel? xeon? processor 5300 series datasheet 111 debug tools specifications 9 debug tools specifications please refer to the debug port design guide for up/dp systems and the appropriate platform design guidelines for information regarding debug tool specifications. section 1.3 provides collateral details. 9.1 debug port system requirements the quad-core intel? xeon? processor 5300 series debug port is the command and control interface for the in-target probe (itp) debugger. the itp enables run-time control of the processors for system debug. the debug port, which is connected to the fsb, is a combination of the system, jtag and execution signals. there are several mechanical, electrical and functional constraints on the debug port that must be followed. the mechanical constraint requires the debug port connector to be installed in the system with adequate physical clearance. electrical constraints exist due to the mixed high and low speed signals of the debug port for the processor. while the jtag signals operate at a maximum of 75 mhz, the execution signals operate at the common clock fsb frequency. the functional constraint requires the debug port to use the jtag system via a handshake and multiplexing scheme. in general, the information in this chapter may be used as a basis for including all run- control tools in quad-core intel? xeon? processor 5300 series based systems designs including tools from vendors other than intel. note: the debug port and jtag signal chain must be designed into the processor board to utilize the xdp for debug purposes except for interposer solutions. 9.2 target system implementation 9.2.1 system implementation specific connectivity and layout guidelines for the debug port are provided in the debug port design guide for up/dp systems and the appropriate platform design guidelines. 9.3 logic analyzer interface (lai) intel is working with two logic analyzer ve ndors to provide logic analyzer interfaces (lais) for use in debugging quad-core inte l? xeon? processor 5300 series systems. tektronix and agilent should be contacted to obtain specific information about their logic analyzer interfaces. the following in formation is general in nature. specific information must be obtained fr om the logic analyzer vendor. due to the complexity of quad-core intel? xeon? processor 5300 series based multiprocessor systems, the lai is critical in providing the ability to probe and capture fsb signals. there are two sets of consider ations to keep in mind when designing a quad-core intel? xeon? processor 5300 series based system that can make use of an lai: mechanical and electrical.
debug tools specifications 112 quad-core intel? xeon? processor 5300 series datasheet 9.3.1 mechanical considerations the lai is installed between the processor so cket and the processor. the lai plugs into the socket, while the processor plugs into a socket on the lai. cabling that is part of the lai egresses the system to allow an electrical connection between the processor and a logic analyzer. the maximum volume occupied by the lai, known as the keepout volume, as well as the cable egress restrict ions, should be obtained from the logic analyzer vendor. system designers must ma ke sure that the keepout volume remains unobstructed inside the system. in some cases, it is known that some of the electrolytic capacitors fall inside of the keepout volume fo r the lai. in this case, it is necessary to move these capacitors to the backside of th e board before using the lai. additionally, note that it is possible that the keepou t volume reserved for the lai may include different requirements from the space normally occupied by the heatsink. if this is the case, the logic analyzer vendor will provide ei ther a cooling solution as part of the lai or additional hardware to mount the existing cooling solution. 9.3.2 electrical considerations the lai will also affect the electrical performance of the fsb, therefore it is critical to obtain electrical load models from each of the logic analyzer vendors to be able to run system level simulations to prove that thei r tool will work in the system. contact the logic analyzer vendor for electrical specific ations and load models for the lai solution they provide.
