1. Introduction
This Technical Product Specification (TPS) provides system-specific information detailing the
features, functionality, and high-level architecture of the Intel®Server System SR1625UR. The
Intel®Server Board S5520UR Technical Product Specification should also be referenced to
obtain greater detail of functionality and architecture specific to the integrated server board, but
which are also supported on this server system.
In addition, design-level information for specific subsystems can be obtained by ordering the
External Product Specifications (EPS) or External Design Specifications (EDS) for a given
subsystem. EPS and EDS documents are not publicly available. They are only made available
under NDA with Intel and must be ordered through your local Intel representative. See the
Reference Documents section at the end of this document for a complete list of available
documents.
The Intel®Server System SR1625UR may contain design defects or errors known as errata,
which may cause the product to deviate from published specifications. Refer to the Intel®Server
Board S5520UR/Intel®Server System SR1625UR Specification Update for published errata.

1.2 Server Board Use Disclaimer
Intel Corporation server boards support add-in peripherals and contain a number of high-
density VLSI and power delivery components that need adequate airflow to cool. Intel ensures
through its own system development and testing that when Intel server building blocks are used
together, the fully integrated system will meet the intended thermal requirements of these
components. It is the responsibility of the system integrator who chooses not to use Intel-
developed server building blocks to consult vendor datasheets and operating parameters to
determine the amount of airflow required for their specific application and environmental
conditions. Intel Corporation cannot be held responsible if components fail or the server board
does not operate correctly when used outside any of their published operating or non-operating
limits.

For a complete updated list of supported processors,
see: http://support.intel.com/support/motherboards/server/S5520UR/. On the Support tab, look
for “Compatibility” and then “Supported Processor List”.
2.1.1 Processor Population Rules
Note: Although the server board does support dual-processor configurations consisting of
different processors that meet the defined criteria below, Intel does not perform validation
testing of this configuation. For optimal system performance in dual-processor configurations,
Intel recommends that identical processors be installed.
When using a single processor configuration, the processor must be installed into the
processor socket labeled CPU1. A terminator is not required in the second processor socket
when using a single processor configuration.
When two processors are installed, the following population rules apply:
Both processors must be of the same processor family.
Both processors must have the same front-side bus speed.
Both processors must have the same cache size.
Processors with different speeds can be mixed in a system, given the prior rules are met.
If this condition is detected, all processor speeds are set to the lowest common
denominator (highest common speed) and an error is reported.
Processor stepping within a common processor family can be mixed as long as it is
listed in the processor specification updates published by Intel Corporation.
The following table describes mixed processor conditions and recommended actions for all
Intel®server boards and systems that use the Intel®5520 Chipset. The errors fall into one of the
following two categories:
Fatal:If the system can boot, it goes directly to the error manager, regardless of
whether the “Post Error Pause” setup option is enabled or disabled.
Major:If the “Post Error Pause” setup option is enabled, system goes directly to the
error manager. Otherwise, the system continues to boot and no prompt is given for the
error. The error is logged to the error manager.

Table 2. Mixed Processor Configurations
Error
Severity
System Action
Processor family not
identical
Fatal
The BIOS detects the error condition and responds as follows:
Logs the error into the system event log (SEL).
Alerts the Integrated BMC of the configuration error with an IPMI
command.
Does not disable the processor.
Displays “0194: Processor family mismatch detected” message
in the error manager.
Halts the system.
Processor cache not
identical
Fatal
The BIOS detects the error condition and responds as follows:
Logs the error into the SEL.
Alerts the Integrated BMC of the configuration error with an IPMI
command.
Does not disable the processor.
Displays “0192: Cache size mismatch detected” message in the
error manager.
Halts the system.
Processor frequency (speed)
not identical
Major
The BIOS detects the error condition and responds as follows:
Adjusts all processor frequencies to lowest common
denominator.
Continues to boot the system successfully.
If the frequencies for all processors cannot be adjusted to be the
same, then the BIOS:
Logs the error into the SEL.
Displays “0197: Processor speeds mismatched” message in the
error manager.
Halts the system.
Processor microcode
missing
Fatal
The BIOS detects the error condition and responds as follows:
Logs the error into the SEL.
Alerts the Integrated BMC of the configuration error with an IPMI
command.
Does not disable processor.
Displays “816x: Processor 0x unable to apply microcode update”
message in the error manager.
Pauses the system for user intervention.
Processor Intel®QuickPath
Interconnect speeds not
identical
Halt
The BIOS detects the error condition and responds as follows:
Logs the error into the system event log (SEL).
Alerts the Integrated BMC of the configuration error with an IPMI
command.
Does not disable the processor.
Displays “0195: Processor Front Side Bus speed mismatch
detected” message in the error manager.
Halts the system.
