 Both processors must have the same number of cores.
 Both processors must have the same cache size for all levels of processor cache
memory.
 Processors with different speeds can be mixed in a system, given the prior rules are met.
If this condition is detected, all processor speeds are set to the lowest common
denominator (highest common speed) and an error is reported.
 Processors which have different Intel
®
Quickpath (QPI) Link Frequencies may operate
together if they are otherwise compatible and if a common link frequency can be
selected. The common link frequency would be the highest link frequency that all
installed processors can achieve.
 Processor stepping within a common processor family can be mixed as long as it is
listed in the processor specification updates published by Intel Corporation.
The following table describes mixed processor conditions and recommended actions for all
Intel
®
server boards and Intel
®
server systems designed around the Intel
®
Xeon
®
processor E5-
2400 product family and Intel
®
C600 chipset product family architecture. The errors fall into one
of the following two categories:
 Fatal: If the system can boot, it pauses at a blank screen with the text “Unrecoverable
fatal error found. System will not boot until the error is resolved” and “Press <F2>
to enter setup” regardless of whether the “Post Error Pause” setup option is enabled or
disabled.
 Major: If the “POST Error Pause” option in BIOS Setup is disabled, the system will log
the error to the BIOS Setup Utility Error Manager and then continue to boot. No POST
error message is given. If the “POST Error Pause” option in BIOS Setup is enabled, the
error is logged and the system goes directly to the Error Manager in BIOS Setup.
 Minor: The message is displayed on the screen or on the Error manager screen, and
the POST Error code is logged to SEL. The system continues booting in a degraded
state. The user may want to replace the erroneous unit. The POST Error Pause option
setting in the BIOS does not have any effect on this error.
Table 3. Mixed Processor Configurations
Error
Severity
System Action
Processor family not
Identical
Fatal
The BIOS detects the error condition and responds as follows:
Logs the POST Error Code into the System Event Log (SEL).
Alerts the BMC to set the System Status LED to steady Amber.
Displays “0194: Processor family mismatch detected” message in
the Error Manager.
Takes Fatal Error action (see above) and will not boot until the fault
condition is remedied.
Processor model not
Identical
Fatal
The BIOS detects the error condition and responds as follows:
Logs the POST Error Code into the System Event Log (SEL).
Alerts the BMC to set the System Status LED to steady Amber.
Displays “0196: Processor model mismatch detected” message in
the Error Manager.
Takes Fatal Error action (see above) and will not boot until the fault
condition is remedied.
