Complete the following steps:
1. If any memory errors are logged other than this one, take actions indicated for those codes first.
2. If no other memory diagnostic codes appear in the logs, verify that all DIMM connectors are
enabled using the Setup utility or the Advanced Settings Utility (ASU).
3. If the problem remains, shut down the system and physically verify that one or more DIMMs are
installed and that all DIMMs are installed in the correct population sequence.
4. If DIMMs are present and properly installed, check for any lit DIMM-connector LEDs, and if
found, reseat those DIMMs.
5. If the problem remains, replace the processor.
6. If the problem remains, replace the system board.

Complete the following steps:
1. You must AC-cycle the system to re-enable the affected DIMM connector or re-enable manually
using the Setup utility.
2. If the system has been recently installed, serviced, moved, or upgraded, check to ensure
that DIMMs are firmly seated and that no foreign material can be seen in the DIMM connector.
If either condition is observed, 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. If the problem persists, replace the DIMM identified by LightPath and/or event log entry.
4. If the problem recurs 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. If
the problem follows a moved DIMM to a different memory channel, replace that DIMM.
