1Introduction
ALL INFORMATION IN THIS DOCUMENT IS SUBJECT TO CHANGE.
The Intel® Xeon® Processor 7200 Series and 7300 Series are multi-processor servers
utilizing four Intel® CoreTM microarchitecture cores. These processors are based on
Intel’s 65 nanometer process technology combining high performance with the power
efficiencies of a low-power microarchitecture. The Quad-Core Intel
Series consists of two die, each die containing two processor cores. The Dual-Core
®
Xeon® 7200 Series consists of two die, each die containing one processor core.
Intel
All processors maintain the tradition of compatibility with IA-32 software. Some key
features include on-die, 64 KB Level 1 instruction data caches per die and 2x4MB
shared Level 2 cache 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 improved performance. The 1066
MHz Front Side Bus (FSB) is a quad-pumped bus running off a 266 MHz system clock
making 8.5 GBytes per second data transfer rates possible. The Quad-Core Intel
Xeon® X7350 processor offers higher clock frequencies than the other Quad-Core
®
Xeon® Processor 7300 Series for platforms that are targeted for the
Intel
performance optimized segment. The Quad-Core Intel® Xeon® L7345 Processor is a
lower voltage, lower power processor.
®
Xeon® 7300
®
Enhanced thermal and power management capabilities are implemented including
Thermal Monitor (TM1), Thermal Monitor 2 (TM2) and Enhanced Intel SpeedStep
®
Technology. TM1 and TM2 provide efficient and effective cooling in high temperature
situations. Enhanced Intel SpeedStep Technology allows trade-offs to be made
between performance and power consumption. This may lower average power
consumption (in conjunction with OS support).
®
The Intel
Xeon® Processor 7200 Series and 7300 Series features include Advanced
Dynamic Execution, enhanced floating point 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 doubleprecision floating point, SIMD integer, and memory management operations.
®
The Intel
Xeon® Processor 7200 Series and 7300 Series support Intel® 64 as an
enhancement to Intel's IA-32 architecture. This enhancement allows the processor to
execute operating systems and applications written to take advantage of the 64-bit
extension technology. Further details on Intel
model can be found in the Intel
®
64 and IA-32 Architectures Software Developer's
®
64 Technology and its programming
Manual.
®
In addition, the Intel
Xeon® Processor 7200 Series and 7300 Series support the
Execute Disable Bit functionality. When used in conjunction 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
The Intel® Xeon® Processor 7200 Series and 7300 Series support Intel® Virtualization
Te chnology 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 Monitor software enabling multiple, independent software
environments inside a single platform. Further details on Intel Virtualization T echnology
can be found at http://developer.intel.com/technology/vt.
®
The Intel
Xeon® Processor 7200 Series and 7300 Series are intended for high
performance multi-processor server systems. The processors support a Multi
Independent Bus (MIB) architecture with one processor on each bus. The MIB
architecture provides improved performance by allowing increased FSB speeds and
bandwidth. All versions of the Intel
®
Xeon® Processor 7200 Series and 7300 Series will
include manageability features. Components of the manageability features include an
OEM EEPROM and Processor Information ROM which are accessed through an SMBus
interface and contain information relevant to the particular processor and system in
which it is installed. The Intel
packaged in a 604-pin Flip Chip Micro Pin Grid Array (FC-mPGA6) package and utilizes
a surface-mount Zero Insertion Force (ZIF) mPGA604 socket. The Intel

power requirements of all frequencies of the processors including Flexible Motherboard
Guidelines (FMB) (see Section 2.11.1). Refer to the appropriate platform design
guidelines for implementation details.
®
The Intel
Xeon® Processor 7200 Series and 7300 Series supports 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 r ate, as in AGP 4X).
Along with the 4X data bus, the address 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 8.5 GBytes per second. The FSB is
also used to deliver interrupts.

Introduction
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 appropriate platform design guidelines (refer to
Section 1.3).
1.1Terminology
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:
• Enhanced Intel SpeedStep

• FSB (Front Side Bus) – The electrical interface that connects the processor to the
chipset. Also referred to as the processor 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.
• Multi Independent Bus (MIB) – A front side bus architecture with one processor
on each bus, rather than a FSB shared between multiple processor agents. The MIB
architecture provides improved performance by allowing increased FSB speeds and
bandwidth.
• Flexible Motherboard Guidelines (FMB) – Are estimates of the maximum
values the Intel® Xeon® Processor 7200, 7300 Series will have over certain time
periods. The values are only estimates and actual specifications for future
processors may differ.
• Functional Operation – Refers to the normal operating conditions in which all
processor specifications, including DC, AC, FSB, signal quality, mechanical and
thermal are satisfied.
• Storage Conditions – Refers to a non-operational state. The processor may be
installed in a platform, in a tray , or loose. Processors may be sealed in packaging or
exposed to free air. Under these conditions, processor pins should not be
connected to any supply voltages, have any I/Os biased or receive any clocks.
Upon exposure to “free air” (that is, unsealed packaging or a device removed from
packaging material) the processor must be handled in accordance with moisture
sensitivity labeling (MSL) as indicated on the packaging material.

Electrical Specifications
2Electrical Specifications
2.1Front Side Bus and GTLREF
Most Intel® Xeon® Processor 7200 Series and 7300 Series FSB signals use Assisted
Gunning Transceiver Logic (AGTL+) signaling 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
power planes for each processor (and chipset), separate V
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_DAT A_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
Table 2-17 for GTLREF_DATA_MID, GTLREF_DATA_END, GTLREF_ADD_MID and
GTLREF_ADD_END specifications). Refer to the applicable platform design guidelines
for details. Termination resistors (R
silicon and are terminated to VTT. 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 eliminating the need to terminate the bus on the
baseboard for most AGTL+ signals.

. Because platforms implement separate

and VTT supplies are
CC
Some FSB signals do not include on-die termination (R
the baseboard. See Table 2-4 and Table 2-6 for details regarding these signals.
The AGTL+ bus depends on incident wave switching. Therefore, timing calculations for
AGTL+ signals are based on flight time as opposed to capacitive deratings. Analog
signal simulation of the FSB, including trace lengths, is highly recommended when
designing a system. Contact your Intel Field Representative to obtain the processor
signal integrity models, which includes buffer and package models.
2.2Decoupling 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 (CBULK), such as electrolytic
capacitors, supply current during longer lasting changes in current demand by the
component, such as coming out of an idle condition. Similarly, 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 voltage provided to the processor

Electrical Specifications
remains within the specifications listed in Table 2-9. Failure to do so can result in
timing violations or reduced lifetime of the component. For further information and
guidelines, refer to the appropriate platform design guidelines.
2.2.1V
2.2.2V
Decoupling
CC
Vcc regulator solutions need to provide bulk capacitance with a low Effective Series
Resistance (ESR). Bulk decoupling must be provided on the baseboard to handle large
current swings. The power delivery solution must ensure the voltage and current
specifications are met (as defined in Table 2-9). For further information regarding
power delivery, decoupling and layout guidelines, refer to the appropriate platform
design guidelines.
Decoupling
TT
Bulk decoupling must be provided on the baseboard. Decoupling solutions must be
sized to meet the expected load. To ensure 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 further information regarding power delivery,
decoupling and layout guidelines, refer to the appropriate platform design guidelines.
2.2.3Front Side Bus AGTL+ Decoupling
The processor integrates signal termination on the die, as well as a portion of the
required high frequency decoupling capacitance 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.
2.3Front 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 processor bus ratio multiplier is set during
manufacturing. The default setting is for the maximum speed of the processor.
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 Model Specific Register (MSR).
Clock multiplying within the processor is provided by the internal phase locked loop
(PLL), which requires a constant frequency BCLK[1:0] input, with exceptions for spread
spectrum clocking. Processor DC and AC specifications for the BCLK[1:0] inputs are
provided in Table 2-18 and Table 2-19, respectively. These specifications must be met
while also meeting signal integrity requirements as outlined in Table 2-18. The
processor utilizes differential clocks. Table 2-1 contains processor core frequency to
FSB multipliers and their corresponding core frequencies.

2.3.1Front Side Bus Frequency Select Signals (BSEL[2:0])
Upon power up, the FSB frequency is set to the maximum supported by the individual
processor. BSEL[2:0] are CMOS outputs that are used to select the FSB frequency.
Please refer to Table 2-11 for DC specifications. Table 2-2 defines the possible
combinations of the signals and the frequency associated with each combination. The
frequency is determined by the processor(s), chipset, and clock synthesizer. All FSB
agents must operate at the same core and FSB frequency. See the appropriate
platform design guidelines for further details.

2.4Voltage Identification (VID)
The Voltage Identification (VID) specification for the processor is defined by the
Voltage Regulator Module (VRM) and Enterprise Voltage Regulator-Down (EVRD) 11.0
Design Guidelines. The voltage set by the VID signals is the reference VR output
voltage to be delivered to the processor Vcc pins. VID signals are asynchronous CMOS

Electrical Specifications
outputs. Please refer to Table 2-12 for the DC specifications for these signals. A voltage
range is provided in Table 2-3 and changes with frequency. The specifications have
been set such that one voltage regulator can operate with all supported frequencies.
Individual processor VID values may be calibrated during manufacturing such that two
devices at the same core frequency may have different default VID settings. This is
reflected by the VID range values provided in Table 2-3.
The processor uses six voltage identification signals, VID[6:1], to support automatic
selection of power supply voltages. Table 2-3 specifies the voltage level corresponding
to the state of VID[6:1]. A ‘1’ in this table refers to a high voltage level and a ‘0’ refers
to a low voltage level. The definition provided in Table 2-3 is not related in any way to
previous Intel
®
Xeon® processors or voltage regulator designs. If the processor socket
is empty (VID[6:1] = 111111), or the voltage regulation circuit cannot supply the
voltage that is requested, the voltage regulator must disable itself. See the Voltage
Regulator Module (VRM) and Enterprise Voltage Regulator-Down (EVRD) 11.0 Design
Guidelines for further details.
Although the Voltage Regulator Module (VRM) and Enterprise Voltage Regulator-Down
(EVRD) 11.0 Design Guidelines defines VID [7:0], VID 7 and VID 0 are not used on the
Dual-Core Intel® Xeon® Processor 7200 Series and Quad-Core Intel® Xeon®
Processor 7300 Series.
The Dual-Core Intel® Xeon® Processor 7200 Series and Quad-Core Intel® Xeon®
Processor 7300 Series provides the ability to operate while transitioning to an adjacent
VID and its associated processor core voltage (V
). This will represent a DC shift in
CC
the load line. It should be noted that a low-to-high or high-to-low voltage state change
may result in as many VID transitions as necessary to reach the target core voltage.
Transitions above the specified VID are not permitted. Table 2-10 includes VID step
sizes and DC shift ranges. Minimum and maximum voltages must be maintained as
shown in Table 2-2 and Table 2-3.
The VRM or EVRD utilized must be capable of regulating its output to the value defined
by the new VID. DC specifications for dynamic VID transitions are included in Table 2-9
and Table 2-10, while AC specifications are included in Table 2-25. Refer to the Voltage
Regulator Module (VRM) and Enterprise Voltage Regulator-Down (EVRD) 11.0 Design
Guidelines for further details.
Power source characteristics must be guaranteed to be stable whenever the supply to
the voltage regulator is stable.
1.When this VID pattern is observed, the voltage regulator output should be disabled.
2.Shading denotes the expected VID range of the Dual-Core Intel® Xeon® Processor 7200 Series and Quad-Core Intel®
Xeon® Processor 7300 Series.
3.The VID range includes VID transitions that may be initiated by thermal events, assertion of the FORCEPR# signal (see
Section 6.2.3), Extended HALT state transitions (see Section 7.2.2), or Enhanced Intel SpeedStep
(see Section 7.3). The Extended HALT state must be enabled for the processor to remain within its specifications.

received, the VRM/EVRD must turn off its output (the output should go to high impedance) within 500 ms and latch off until

2.5Reserved, Unused, or Test Signals
All Reserved signals must remain unconnected. Connection of these signals to VCC, VTT,
, or to any other signal (including each other) can result in component malfunction

SS
or incompatibility with future processors. See Section 4 for a pin 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
interfere with some TAP functions, complicate 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 within ± 20% of the impedance of the baseboard
trace for FSB signals, unless otherwise noticed 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
TAP, Asynchronous GTL+ inputs, and Asynchronous GTL+ outputs do not include ondie 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.

Electrical Specifications
For each processor socket, connect the TESTIN1 and TESTIN2 signals together, then
terminate the net with a 51 Ω resistor to V
TT
The TESTHI signal must be tied to the processor VTT 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 Ω, then a value
between 40 Ω and 60 Ω is required.
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
2.6Front 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” refers to the AGTL+ output 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 transistor to assist during the first clock of
a low-to-high voltage transition.
With the implementation of a source synchronous 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 rising edge of BCLK0 (ADS#, HIT#, HITM#, etc.) and the
second set is for the source synchronous signals which are relative to their respective
strobe lines (data and address) as well as rising edge of BCLK0. Asynchronous signals
are still present (A20M#, IGNNE#, etc.) and can become active at any time during the
clock cycle. Table 2-4 identifies which signals are common clock, source synchronous
and asynchronous.

Asynchronous Signals
TT
Legacy input signals such as A20M#, IGNNE#, INIT#, SMI#, and STPCLK# utilize
CMOS input buffers. Legacy output signals such as FERR#/PBE#, IERR#, PROCHOT#,
THERMTRIP#, and TDO utilize open drain output buffers. All of the CMOS and Open
Drain signals are required to be asserted/deasserted for at least eight BCLKs in order
for the processor to recognize the proper signal state. See Section 2.11 and
Section 2.12 for the DC and AC specifications. See Section 7 for additional timing
requirements for entering and leaving the low power states.
2.8Test Access Port (TAP) Connection
Due to the voltage levels supported by other components in the Test Access Port (TAP)
logic, it is recommended that the processor(s) be first in the TAP chain and followed by
any other components within the system. A translation buffer should be used to
connect to the rest of the chain unless one of the other components is capable of
accepting an input of the appropriate voltage. Similar considerations must be made for
TCK, TMS, and TRST#. Two copies of each signal may be required with each driving a
different voltage level.

Electrical Specifications
2.9Mixing Processors
Intel supports and validates multi-processor configurations only in which all processors
operate with the same FSB frequency, core frequency, number of cores, and have the
same internal cache sizes. Mixing components operating at different internal clock
frequencies or number of cores is not supported and will not be validated by Intel.
Note:Processors within a system must operate at the same frequency per bits [12:8] of the
CLOCK_FLEX_MAX MSR; however this does not apply to frequency transitions initiated
due to thermal events, Extended HALT, Enhanced Intel SpeedStep technology
transitions, or assertion of the FORCEPR# signal (See Section 6).
Mixing processors of different steppings but the same model (as per CPUID instruction)
is supported. Details regarding the CPUID instruction are provided in the AP-485 Intel®
Processor Identification and the CPUID Instruction application note.
2.10Absolute Maximum and Minimum Ratings
Table 2-8 specifies absolute maximum and minimum r atings only, which lie outside the
functional limits of the processor. Only within specified operation limits, can
functionality and long-term reliability be expected.
At conditions outside functional operation condition limits, but within absolute
maximum and minimum ratings, neither functionality nor long-term reliability can be
expected. If a device is returned to conditions within functional operation limits after
having been subjected to conditions outside these limits, but within the absolute
maximum and minimum ratings, the device may be functional, but with its lifetime
degraded depending on exposure to conditions exceeding the functional operation
condition limits.
At conditions exceeding absolute maximum and minimum ratings, neither functionality
nor long-term reliability can be expected. Moreover, if a device is subjected to these
conditions for any length of time then, when returned to conditions within the
functional operating condition limits, it will either not function or its reliability will be
severely degraded.
Although the processor contains protective circuitry to resist damage from static
electric discharge, precautions should always be taken to avoid high static voltages or
electric fields.

Notes:
1.For functional operation, all processor electri cal, signal quality, mechanical and thermal specifications must
be satisfied.
2.Storage temperature is applicable to storage conditions only. In this scenario, the processor must not
receive a clock, and no pins can be connected to a voltage bias. Storage within these limits will not affect
the long-term reliability of the device. For functional operation, please refer to the processor case
temperature specifications.

2.11.2Platform Environmental Control Interface (PECI) DC
Specifications
PECI is an Intel proprietary one-wire bus interface that provides a communication
channel between Intel processor and external thermal monitoring devices. The DualCore Intel® Xeon® Processor 7200 Series and Quad-Core Intel® Xeon® Processor

Document Number: 318080-00235
7300 Series contains Digital Thermal Sensors (DTS) distributed throughout the die.
These sensors are implemented as analog-to-digital converters calibrated at the factory
for reasonable accuracy to provide a digital representation of relative processor
temperature. PECI provides an interface to relay the highest DT S temperature within a
die to external management devices for thermal/fan speed control.

Core voltage (VCC) overshoot events at the processor must meet the specifications in
Table 2-16 when measured across the VCC_SENSE and VSS_SENSE pins and across
the VCC_SENSE2 and VSS_SENSE2 pins. Overshoot events that are < 10 ns in duration
may be ignored. These measurements of processor die level overshoot should be taken
with a 100 MHz bandwidth limited oscilloscope.
2.11.4AGTL+ FSB Specifications
Routing topologies are dependent on the processors supported and the chipset used in
the design. Please refer to the appropriate platform design guidelines for specific
implementation details.In most cases, termination resistors are not required as these
are integrated into the processor silicon. See Table 2-6 for details on which signals do
not include on-die termination. Please refer to Table 2-17 for R
Valid high and low levels are determined by the input buffers via comparing with a
reference voltage called GTLREF_DATA_MID, GTLREF_DATA_END, GTLREF_ADD_MID,
and GTLREF_ADD_END. GTLREF_DATA_MID and GTLREF_DATA_END are the reference
voltage for the FSB 4X data signals, GTLREF_ADD_MID and GTLREF_ADD_END are the
reference voltage for the FSB 2X address signals and common clock signals. Table 2-17
lists the GTLREF_DATA_MID, GTLREF_DATA_END, GTLREF_ADD_MID, and
GTLREF_ADD_END specifications.
The AGTL+ reference voltages (GTLREF_DATA_MID, GTLREF_DATA_END,
GTLREF_ADD_MID, and GTLREF_ADD_END) must be generated on the baseboard
using high precision voltage divider circuits. Refer to the appropriate platform design

2.12Front Side Bus AC Specifications
The processor FSB timings specified in this section are defined at the
processor core (pads). Therefore, proper simulation of the FSB is the only
means to verify proper timing and signal quality.
See Table 4-1 for the pin listing and Table 5-1 for signal definitions. Table 2-19 through
Table 2-24 list the AC specifications associated with the processor FSB.
All AGTL+ timings are referenced to GTLREF_DATA_MID, GTLREF_DATA_END,
GTLREF_ADD_MID, and GTLREF_ADD_END for both ‘0’ and ‘1’ logic levels unless
otherwise specified.
The timings specified in this section should be used in conjunction with the processor
signal integrity models provided by Intel. AGTL+ layout guidelines are also available in
the appropriate platform design guidelines.
Note:Care should be taken to read all notes associated with a particular timing parameter.

The Intel® Xeon® Processor 7200 Series and 7300 Series is packaged in a FC-mPGA6
package that interfaces with the motherboard via a mPGA604 socket. The package
consists of two processor dies mounted on a substrate pin-carrier. An IHS is attached
to the package substrate and die and serves as the mating surface for processor
component thermal solutions, such as a heatsink. Figure 3-1 shows a sketch of the
processor package components and how they are assembled together. Refer to the
mPGA604 Socket Design Guidelines for complete details on the mPGA604 socket.
The package components shown in Figure 3-1 include the following:
1. IHS
2. Processor die
3. FC-m PGA 6 pack age
4. Pin-side capacitors
5. Package pin

3.3Package Loading Specifications
Table 3-1 provides dynamic and static load specifications for the processor package.
These mechanical load limits should not be exceeded during heatsink assembly,
shipping conditions, or standard use condition. Also, any mechanical system or
component testing should not exceed the maximum limits. The processor package
substrate should not be used as a mechanical reference or load-bearing surface for
thermal and mechanical solutions. The minimum loading specification must be
maintained by any thermal and mechanical solution.

Notes:
1. These specifications apply to uniform compressive loading in a direction perpendicular to the IHS top surface.
2. This is the minimum and maximum static force that can be applied by the heatsink and retention solution to
maintain the heatsink and processor interface.
3. These parameters are based on limited testing for design characterization. Loading limits are for the package
only and do not include the limits of the processor socket.
4. This specification applies for thermal retention solutions that allow baseboard deflection.
5. This specification applies either for thermal retention solutions that prevent baseboard deflection or for the
Intel enabled reference solution (CEK).
6. Dynamic loading is defined as an 11 ms duration average load superimposed on the static load requirement.
7. Experimentally validated test condition used a heatsink mass of 1 lbm (~0.45 kg) with 100 G acceleration
measured at heatsink mass. The dynamic portion of this specification in the product application can have
flexibility in specific values, but the ultimate product of mass times acceleration should not exceed this
validated dynamic load (1 lbm x 100 G = 100 lb).
8. Transient loading is defined as a 2 sec ond duration peak load superimposed on the static load requirement,
representative of loads experienced by the package during heatsink installation.

Thermal Specifications
6Thermal Specifications
6.1Package Thermal Specifications
The Intel® Xeon® Processor 7200 Series and 7300 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 system. As processor technology changes,
thermal management becomes increasingly crucial when building computer systems.
Maintaining the proper thermal environment is key to reliable, long-term system
operation.
A complete solution includes both component 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 developing a complete thermal solution. For
more information on designing a component level thermal solution, refer to the Dual-
Core Intel® Xeon® Processor 7200 Series and Quad-Core Intel® Xeon® Processor
7300 Series Thermal / Mechanical Design Guide.
6.1.1Thermal 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 (TCASE) specifications as defined by the applicable thermal profile (see
Table 6-1 and Figure 6-1 for Quad-Core Intel® Xeon® Processor E7300 Series,
Table 6-3 and Figure 6-2 for Quad-Core Intel® Xeon® X7350 Processor, Table 6-5 and
Figure 6-3 for Quad-Core Intel® Xeon® L7345 Processor, Table 6-7 and Figure 6-4 for
Dual-Core Intel® Xeon® Processor 7200 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
Dual-Core Intel® Xeon® Processor 7200 Series and Quad-Core Intel® Xeon®
Processor 7300 Series Thermal / Mechanical Design Guide.

managing processor temperatures which is intended to support acoustic noise
reduction through fan speed control and to assure 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 should be designed to use this data. Systems that do not
alter the fan speed also need to guarantee the case temperature meets the thermal
profile specifications.
The Quad-Core Intel® Xeon® Processor E7300 Series (see Figure 6-1; Table 6-2),
Quad-Core Intel® Xeon® L7345 Processor (see Figure 6-3; Table 6-6) and Dual-Core
Intel® Xeon® Processor 7200 Series (see Figure 6-4; Table 6-8) supports a single
Thermal Profile. The Thermal Profile is indicative of a constrained thermal environment
(Ex: 1U form factor). Because of the reduced cooling capability represented by this
solution, the probability of TCC activation and performance loss is increased.
Xeon® Processor 7200 Series and 7300 Series implement a methodology for

Thermal Specifications
Additionally , utilization of a thermal solution that does not meet the Thermal Profile will
violate the thermal specifications and may result in permanent damage to the
processor. Refer to the Dual-Core Intel® Xeon® Processor 7200 Series and Quad-Core Intel® Xeon® Processor 7300 Series Thermal / Mechanical Design Guide for
details on system thermal solution design, thermal profiles and environmental
considerations.
For the Quad-Core Intel® Xeon® X7350 Processor, Intel has developed a thermal
profile which must be met to ensure adherence to Intel reliability requirements. The
Thermal Profile (see Figure 6-2; Table 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. Intel has
developed the thermal profile to allow customers to choose the thermal solution and
environmental parameters that best suit their platform implementation. Refer to the
Dual-Core Intel® Xeon® Processor 7200 Series and Quad-Core Intel® Xeon®
Processor 7300 Series Thermal / Mechanical Design Guide for details on system
thermal solution design, thermal profiles and environmental considerations.
The upper point of the thermal profile consists of the Thermal Design Power (TDP) and
the associated T

value. It should be noted that the upper point associated with
CASE

P @ 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 QuadCore Intel® Xeon® X7350 Processor).
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 event that an application exceeds the TDP
recommendation for a sustained time period. For more details on this feature, refer to
Section 6.2. To ensure maximum flexibility for future requirements, systems should be
designed to the Flexible Motherboard (FMB) guidelines, even if a processor with lower
power dissipation is currently planned. Thermal Monitor and Thermal Monitor 2
