Mixing Processors
Intel supports dual-processor (DP) configurations consisting of processors:
• from the same power optimization segment.
• that support the same maximum Intel QuickPath Interconnect and DDR3 memory
• that support the same maximum Intel QuickPath Interconnect and DDR3 memory
speeds.
• that share symmetry across physical packages with respect to the number of
logical processor per package, number of cores per package, number of Intel
QuickPath Interconnect interfaces, and cache topology.
QuickPath Interconnect interfaces, and cache topology.
• that have identical Extended Family, Extended Model, Processor Type, Family Code
and Model Number as indicated by the Function 1 of the CPUID instruction.
Note:
Processors must operate with the same Intel QuickPath Interconnect, DDR3 memory
and core frequency.
While Intel does nothing to prevent processors from operating together, some
combinations may not be supported due to limited validation, which may result in
uncharacterized errata. Coupling this fact with the large number of Intel Xeon
processor 5600 series processor attributes, the following population rules and stepping
matrix have been developed to clearly define supported configurations.

• Processors must operate at the same core frequency. Note, processors within the
same power-optimization segment supporting different maximum core frequencies
can be operated within a system. However, both must operate at the highest
frequency rating commonly supported. Mixing components operating at different
internal clock frequencies is not supported and will not be validated by Intel.
