Complete the following steps:
1. If the DIMM was disabled because of a memory fault, follow the procedure for that event.
2. If no memory fault is recorded in the logs and no DIMM connector error LEDs are lit, re-enable
the DIMM through the Setup utility or the Advanced Settings Utility (ASU).
3. If problem persists, Power cycle the node from management console.
4. Reset IMM to default settings.
5. Reset UEFI to default settings.
6. Reflash IMM and UEFI firmware.

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. Also, check IBM support
site for an applicable Service Bulletins (Service bulletins) that applies to this memory error.
(Link to IBM support service bulletins)
3. If the previous steps do not resolve the problem, at the next maintenance opportunity, swap
the 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. If this is a flash DIMM, make sure it is still under
warranty before replacing it.
4. (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 the system board.
5. (Trained service technician only) Remove affected Processor and inspect Processor socket pins
for damaged or mis-aligned pins. If socket is damaged, replace the system board.
6. (Trained Service technician only) Replace affected processor.
7. (Trained Service technician only) Replace the system board.
