S.51003 • S.51006
S.51003 [S.51003] An uncorrectable memory error was detected in DIMM slot % on rank %.
Explanation: One of the following has occurred:
v An uncorrectable memory error was detected on processor % channel %. The failing DIMM within the channel
could not be determined.
v An uncorrectable memory error has been detected during POST.
v Fatal Memory Error Occurred
Severity: Error
User response: Complete the following steps:
1. Refer to TIP H212293 for the minimum code level.
2. If the system was recently installed, moved, serviced, or upgraded, verify that the specified DIMM is seated
properly 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 or the problem persists, replace the DIMM identified by the
light path LEDs or the event log entry.
4. If problem re-occurs on the same DIMM connector, replace the other DIMMs on the same memory channel.
5. Check the IBM support site for service bulletins or firmware updates that apply to this memory error.
6. If problem re-occurs on the same DIMM connector, inspect connector for damage. If damage is found, replace the
system board.
7. Swap processors to see if the error follows the processor. If is does, replace the affected processor.
8. Replace the system board.
S.51006 [S.51006] A memory mismatch has been detected. Please verify that the memory configuration is
valid.
Explanation: One or more mismatched DIMMs were detected.
Severity: Error
User response: Complete the following steps:
1. Check the log for any events related to an uncorrectable memory error or failed memory test and resolve those
issues. DIMMs being disabled by other errors or actions could cause this event.
2. Verify that matching DIMMs are installed in the correct population sequence, according to the product
documentation for the system. See the section entitled, "Installing a DIMM" for more information.
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 the UEFI firmware.
Replace the DIMM.
5.
Swap processors to see if the error follows the processor. If is does, replace the affected processor.
6.
