What are the processor configuration error messages?

Error Severity System Action Recommended Action
Processor Family Not Identical & Processor Cache not Identical Fatal The BIOS detects the error condition and responds as follows:
  • Logs the error into the system event log (SEL).
  • Alerts the Integrated BMC of the configuration error with an IPMI command.
  • Does not disable the processor.
  • Displays “0194: Processor family mismatch detected” message in the error manager.
  • Halts the system.
Use the same processor family.

Check the processor compatibility list.

Check the System Event Log for specific error.
Processor frequency (Speed) not identical Major The BIOS detects the error condition and responds as follows:
  • Adjusts all processor frequencies to lowest common denominator.
  • Continues to boot the system successfully.
  • If the frequencies for all processors cannot be adjusted to be the same, then the BIOS:
  • Logs the error into the SEL.
  • Displays “0197: Processor speeds mismatched” message in the error manager.
  • Halts the system
Use the same processor family & speed.

Check the processor compatibility list.

Check the System Event Log for specific error.
Processor Microcode missing Fatal The BIOS detects the error condition and responds as follows:
  • Logs the error into the SEL.
  • Alerts the Integrated BMC of the configuration error with an IPMI command.
  • Does not disable processor.
  • Displays “816x: Processor 0x unable to apply microcode update” message in the error manager.
  • Pauses the system for user intervention.
Check the processor compatibility list.

Update the system BIOS to the latest version.

Check the System Event Log for specific error.
Processor Intel® QuickPath Interconnect speeds not identical Halt The BIOS detects the error condition and responds as follows:
  • Logs the error into the system event log (SEL).
  • Alerts the Integrated BMC of the configuration error with an IPMI command.
  • Does not disable the processor.
  • Displays “0195: Processor Front Side Bus speed mismatch detected” message in the error manager.
  • Halts the system
Check the processor compatibility list.

Use the same processor family & speed.

Check the System Event Log for specific error.
