User Response
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 firmware update that applies to this memory error. The
release notes will list the known problems the update addresses.
3. If the previous steps do not resolve the problem, at the next maintenance opportunity, replace
the affected DIMM (as indicated by LightPath and/or failure log entry).
4. If PFA re-occurs on the same DIMM connector, swap the other DIMMs on the same memory
channel 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 PFA follows a
moved DIMM to any DIMM connector on the different memory channel, replace the moved
DIMM.
5. Check IBM support site for an applicable Service Bulletins (Service bulletins) that applies to this
memory error. (Link to IBM support service bulletins)
6. (Trained service technician only) If problem continues to re-occur on the same DIMM connector,
inspect DIMM connector for foreign material and remove, if found. If connector is damaged,
replace system board.
7. (Trained service technician only) Remove affected Processor and inspect Processor socket pins
for damaged or mis-aligned pins. If damage is found or Processor is an upgrade part, replace
system board.
8. (Trained Service technician only) Replace affected processor.
9. (Trained Service technician only) Replace system board.
• W.58007 [W.58007] Invalid memory configuration (Unsupported DIMM Population) detected. Please
verify memory configuration is valid.
