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.
Processor cores/threads not
identical
Fatal
The BIOS detects the error condition and responds as follows:
Logs the POST Error Code into the SEL.
Alerts the BMC to set the System Status LED to steady Amber.
Displays “0191: Processor core/thread count mismatch
detected” message in the Error Manager.
 Takes Fatal Error action (see above) and will not boot until the
fault condition is remedied.
Processor cache not
identical
Fatal
The BIOS detects the error condition and responds as follows:
Logs the POST Error Code into the SEL.
Alerts the BMC to set the System Status LED to steady Amber.
Displays “0192: Processor cache size mismatch detected
message in the Error Manager.
 Takes Fatal Error action (see above) and will not boot until the
fault condition is remedied.
Processor frequency (speed)
not identical
Fatal
The BIOS detects the processor frequency difference, and responds
as follows:
Adjusts all processor frequencies to the highest common frequency.
No error is generated – this is not an error condition.
Continues to boot the system successfully.
If the frequencies for all processors cannot be adjusted to be the
same, then this is an error, and the BIOS responds as follows:
Logs the POST Error Code into the SEL.
Alerts the BMC to set the System Status LED to steady Amber.
Does not disable the processor.
Displays “0197: Processor speeds unable to synchronize”
message in the Error Manager.
 Takes Fatal Error action (see above) and will not boot until the
fault condition is remedied.
