Complete the following steps:

  1. Could follow an uncorrectable memory error or failed memory test. Check log and service that event first. DIMMs disabled by other errors or actions could cause this event.
  2. Verify that the DIMMs are installed in the correct population sequence, according to the service information for this product.
  3. Disable memory mirroring and sparing. If this action eliminates the mismatch, check IBM Support site for information related to this problem.
  4. Reflash UEFI firmware.
  5. Replace DIMM
  6. (Trained Service technician only) Replace Processor.
