S.51003 • S.51006
S.51003 [S.51003]
Explanation: An uncorrectable memory error was detected in DIMM slot % on rank %. [S.51003] An uncorrectable
memory error was detected on processor % channel %. The failing DIMM within the channel could not be
determined. [S.51003] An uncorrectable memory error has been detected. Fatal Memory Error Occurred
Severity: Error
User response: Complete the following steps:
1. Check IBM support site for an applicable service bulletin or firmware update that applies to this memory error.
2.
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 580A4
event denoting detected change in DIMM population that could be related to this problem.)
3. If no problem is observed on the DIMM connectors and the problem persists, replace the DIMM identified by
LightPath and/or event log entry.
4. If problem re-occurs on the same DIMM connector, swap the other DIMMs on the same memory channel across
channels one at a time to a different memory channel or Processor. (check service information for this
product/Install guide for population requirements for sparing/paring modes). If problem follows a moved DIMM
to a different memory channel, replace that DIMM.
5. (Trained service technician only) Remove affected Processor and inspect Processor socket pins for damaged or
mis-aligned pins. If damage is found, or this is an upgrade Processor, replace the system board. If there are
multiple Processor's, swap Processor's to move affected Procesor to another Processor socket and retry. If problem
follows the affected Processor (or there is only one Processor), replace the affected Processor.
6. (Trained technician only)If problem stays with the original DIMM connector, re-inspect DIMM connector for
foreign material and remove, if found. If connector is damaged, replace system board
S.51006 [S.51006]
Explanation: A memory mismatch has been detected. Please verify that the memory configuration is valid. One or
More Mismatched DIMMs Detected
Severity: Error
User response: Complete the following steps:
1. Could follow an uncorrectable memory error or failed memory test. Check the 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.
3. Disable memory mirroring and sparing. If this action eliminates the mismatch, check the IBM Support site for
information related to this problem.
4. Update UEFI firmware.
5. Replace the DIMM.
6. Replace the processor.
