Intel® Server System SR1600UR TPS 1BProduct Overview
Revision 1.8 Intel order number E45725-010
2.1.1 Processor Support
The Intel
®
Server Boards S5520UR supports the following processors:
One or two Intel
®
Xeon
®
Processor 5500 Series with a 4.8 GT/s, 5.86 GT/s, or 6.4 GT/s
Intel
®
QPI link interface and Thermal Design Power (TDP) up to 95 W.
One or two Intel
®
Xeon
®
Processor 5600 Series with a 6.4 GT/s Intel
®
QPI link interface
and Thermal Design Power (TDP) up to 130 W.
Note: When configured with 130W processors,only Single & Dual Rank DIMMs are supported.
The server boards do not support previous generations of the Intel
®
Xeon
®
Processors.
For a complete updated list of supported processors, see:

Compatibility and then Supported Processor List.
2.1.1.1 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.
