Microcode Update Error Received after Upgrading Intel® Processor

Intel® Processors allow for minor software updates from within the motherboard BIOS specific to the processor stepping. The processor stepping is similar to a hardware version. As minor modifications are made to the processor design, such as errata corrections, the stepping number is incremented.

If the BIOS does not properly identify the processor stepping, you may encounter one of the following microcode update errors: 

  • Error: "Microcode update required"
  • Error: "Microcode was not found in the system BIOS for the installed CPU"
  • Error: "BIOS update data incorrect"

To resolve a microcode update error, contact the system or motherboard manufacturer for the appropriate BIOS update files and instructions.

Prior to installing a BIOS revision, verify the 'Allow BIOS Update' option is enabled in the BIOS (if applicable).

If the system or motherboard manufacturer does not provide BIOS update files, the manufacturer may not validate the motherboard for use with the processor being installed. In this case, the processor is incompatible with the motherboard.
