Table 28. Mixed Processor Configurations - Intel S7000FC4UR Technical Product Specification

BIOS Initialization
14.1.18.4 Mixed Processor Speeds
Processors with different speeds can be mixed in a system. If this condition is detected, all
processor speeds are set to the lowest common denominator (highest common speed) if
possible. See Table 28 for more information.
14.1.18.5 Mixed Processor Cache Sizes
The size of all cache levels must match between all installed processors. Processor cache size
mismatches are reported as an error. See Table 28.
14.1.18.6 Microcode Update Not Available
If the system BIOS detects a processor for which a microcode update is not available, the BIOS
reports an error as described in Table 28.
14.1.18.7 Mixed Processor Configuration
The following table describes mixed processor conditions and recommended actions for all
®
Intel server boards and systems. See Section 19.3.3 for a description of error severity and
classification.

Table 28. Mixed Processor Configurations

Logs the error into the System Event Log (SEL)
Alerts the BMC of the configuration error with the IPMI Set Processor State
command indicating a configuration error for all mismatched processors.
Does not disable the processor
Displays "0194: Processor family mismatch detected" message in the POST
Error Manager.
Halts the system
Logs the error into the SEL
Alerts the BMC of the configuration error with the IPMI Set Processor State
command indicating a configuration error for all mismatched processors.
BIOS does not disable the processor
Displays "0192: Cache size mismatch detected" message in the POST Error
Manager.
Halts the system
Adjusts all processor frequencies to lowest common denominator
Continues to boot the system successfully
If the frequencies for all processors cannot all be adjusted to be identical, then the
BIOS:
Logs the error into the SEL
Alerts the BMC of the configuration error with the IPMI Set Processor State
command indicating a configuration error for all mismatched processors.
Displays "0197: Processor speeds mismatched" message in the POST Error
Manager.
