Microcode Update Error Received After Upgrading Processor

Intel® Processors allow for minor software updates from within the motherboard BIOS specific to the stepping of the installed processor. 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, a microcode update error may be encountered.

  • 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 to obtain 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, it is possible that the manufacturer has not or will not validate the motherboard for use with the processor that is being installed. In such an instance, the processor is incompatible with the motherboard.
