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 configuration. 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 "CPU_1".
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 number of cores.

Both processors must have the same cache sizes for all levels of processor cache
memory.

Processors with different core frequencies can be mixed in a system, given the prior
rules are met. If this condition is detected, all processor core frequencies are set to the
lowest common denominator (highest common speed) and an error is reported.

Processors which have different QPI link frequencies may operate together if they are
otherwise compatible and if a common link frequency can be selected. The common link
frequency would be the highest link frequency that all installed processors can achieve.

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.

Processor Initialization Error Summary

The following table describes mixed processor conditions and recommended actions for all
Intel server boards and Intel server systems designed around the Intel
®
2600 product family and Intel
of the following three categories:
Fatal: If the system can boot, it pauses at a blank screen with the text "Unrecoverable

fatal error found. System will not boot until the error is resolved" and "Press <F2>
to enter setup", regardless of whether the "Post Error Pause" setup option is enabled or
disabled.
When the operator presses the <F2> key on the keyboard, the error message is
displayed on the Error Manager screen, and an error is logged to the System Event Log
(SEL) with the POST Error Code.
The system cannot boot unless the error is resolved. The user needs to replace the
faulty part and restart the system.
For Fatal Errors during processor initialization, the System Status LED will be set to a
steady Amber color, indicating an unrecoverable system failure condition.
Major: If the "Post Error Pause" setup option is enabled, the system goes directly to the

Error Manager to display the error, and logs the POST Error Code to SEL. Operator
