• Processors must share symmetry across physical packages with respect to the
number of logical processors per package, number of cores per package (but not
necessarily the same subset of cores within the packages), number of Intel
QuickPath Interconnect interfaces and cache topology.

• Mixing steppings is only supported with processors that have identical Extended
Family, Extended Model, Processor Type, Family Code and Model Number as
indicated by the Function 1 of the CPUID instruction. Mixing processors of different
steppings, but the same mode (as per CPUID instruction) is supported. Details
regarding the CPUID instruction are provide in the Intel

• After AND’ing the feature flag and extended feature flags from the installed
processors, any processor whose set of feature flags exactly matches the AND’ed
feature flags can be selected by the BIOS as the BSP. If no processor exactly
matches the AND’ed feature flag values, then the processor with the numerically
lower CPUID should be selected as the BSP.

• Intel requires that the proper microcode update be loaded on each processor
operating within the system. Any processor that does not have the proper
microcode update loaded is considered by Intel to be operating out-of-specification.

Note:
Processors within a system must operate at the same frequency per bits [15:8] of the
FLEX_RATIO MSR (Address: 194h); however this does not apply to frequency

Flexible Motherboard Guidelines (FMB)
The Flexible Motherboard (FMB) guidelines are estimates of the maximum values the
processor will have over certain time periods. The values are only estimates and actual
specifications for future processors may differ. Processors may or may not have
specifications equal to the FMB value in the foreseeable future. System designers
should meet the FMB values to ensure their systems will be compatible with future
processors.

Absolute Maximum and Minimum Ratings
specifies absolute maximum and minimum ratings only, which lie outside the
functional limits of the processor. Only within specified operation limits, can
functionality and long-term reliability be expected.
functionality and long-term reliability be expected.
At conditions outside functional operation condition limits, but within absolute
maximum and minimum ratings, neither functionality nor long-term reliability can be
expected. If a device is returned to conditions within functional operation limits after
having been subjected to conditions outside these limits, but within the absolute
maximum and minimum ratings, the device may be functional, but with its lifetime
degraded depending on exposure to conditions exceeding the functional operation
condition limits.

At conditions exceeding absolute maximum and minimum ratings, neither functionality
