3.1.6.2
Mixed Processor Steppings
For optimum system performance, only identical processors should be installed in a system.
Processor steppings within a common processor family can be mixed in a system provided that
there is no more than a one stepping difference between them. If the installed processors are
more than one stepping apart, an error is reported. Acceptable mixed steppings are not reported
as errors by the BIOS.
3.1.6.3
Mixed Processor Models
Processor models cannot be mixed in a system. If this condition is detected, error 8196 is
logged in the SEL.
3.1.6.4
Mixed Processor Families
Processor families cannot be mixed in a system. If this condition is detected, error 8194 is
logged in the SEL.
3.1.6.5
Mixed Processor Cache Sizes
If the installed processors have mixed cache sizes, error 8192 will be logged in the SEL. The
size of all cache levels must match between all installed processors. Mixed cache processors
are not supported.
3.1.6.6
Jumperless Processor Speed Settings
The Intel
®
Xeon
®
processor does not utilize jumpers or switches to set the processor frequency.
The BIOS reads the highest ratio register from all processors in the system. If all processors are
the same speed, the Actual Ratio register is programmed with the value read from the High
Ratio register. If all processors do not match, the highest common value between High and Low
Ratio is determined and programmed to all processors. If there is no value that works for all
installed processors, all processors not capable of speeds supported by the boot strap
processor (BSP) are disabled and an error is displayed.
3.1.6.7 Microcode
IA-32 processors have the capability of correcting specific errata through the loading of an Intel
supplied data block, i.e., microcode update. The BIOS is responsible for storing the update in
non-volatile memory and loading it into each processor during POST. The BIOS allows a
number of microcode updates to be stored in the flash, limited by the amount of free space
available. The BIOS supports variable size microcode updates. The BIOS verifies the signature
prior to storing the update in the flash.
3.1.6.8 Processor
Cache
The BIOS enables all levels of processor cache as early as possible during POST. There are no
user options to modify the cache configuration, size or policies. The largest and highest level
cache detected is reported in the BIOS Setup.
