User response

This error generally follows another memory error. If you already performed the actions for the previous uncorrectable memory error, no additional action is required. If not, perform these steps:
  1. Check the IBM Support Web page for related service bulletins.
  2. Check the blade server BIOS change history on the Web for any memory related fixes. Update the BIOS if applicable.
  3. Use Light Path diagnostics to verify the affected DIMM bank.
    1. Record the DIMM part number and size for future reference.
      Note: For some blade servers, the DIMM part number is available through the advanced management module Web interface.
    2. Verify that the memory DIMM is supported on the IBM ServerProven Web site.
  4. Check to make sure the DIMMs are seated properly (especially if this is a new installation). If the DIMMs required reseating, boot the blade into BIOS setup and enable the memory bank.
  5. Replace the DIMMs in the memory bank, boot the blade server to BIOS setup and enable the memory bank.
