3.1.2 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 these configurations. 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.
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 that 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 will be the highest link frequency that all installed processors can
achieve.
