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, reenable
the DIMM through the Setup utility or the Advanced Settings Utility (ASU).
3. If the problem persists, Power cycle the compute node from the management console.
4. Reset the IMM to default settings.
5. Reset UEFI to default settings.

Complete the following steps:
1. Prior to replacing memory DIMM, refer to TIP H212154 for minimum code level.
2. If the compute 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: The event Log might contain a recent 00580A4 event denoting detected
change in DIMM population that could be related to this problem.)
3. Check the 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.
4. 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).
5. 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. If PFA follows a moved DIMM
to any DIMM connector on the different memory channel, replace the moved DIMM.
6. Check the IBM support site for an applicable Service Bulletins (Service bulletins) that applies
to this memory error. (Link to IBM support service bulletins)
7. 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.
