Complete the following steps:
1. If the node has recently been installed, moved, serviced, or upgraded, verify that the DIMM is
properly seated and visually verify that there is no foreign material in any DIMM connector on that
memory channel. If either of these conditions is found, correct and retry with the same DIMM.
(Note: Event Log may contain a recent 00580A4 event denoting detected change in DIMM
population that could be related to this problem.)
2. Check IBM support site for an applicable service bulletin or firmware update that applies to this
memory error.
3. If no problem is observed on the DIMM connectors or the problem persists, replace the DIMM
identified by LightPath and/or event log entry. If this is a flash DIMM, make sure it is still under
warranty before replacing it.
4. If problem re-occurs on the same DIMM connector, replace the other DIMMs on the same
memory channel. If this is a flash DIMM, make sure it is still under warranty before replacing it
5. Replace compute book.
6. (Trained Service technician only) Replace affected Processor.

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. If this is a flash DIMM, make sure it is still under warranty before replacing it.
6. (Trained Service technician only) Replace Processor.
