      Complete the following steps:

              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.)
             Check IBM support site for an applicable service bulletin or firmware update that applies to this memory error.  
             If no problem is observed on the DIMM connectors or the problem persists, replace the DIMM identified by LightPath and/or event log entry.  If this is a flash DIMM, make sure it is still under warranty before replacing it.
             If problem re-occurs on the same DIMM connector, replace the other DIMMs on the same memory channel.  If this is a flash DIMM, make sure it is still under warranty before replacing it
             (Trained service technician only) Replace Processor.  Inspect Processor socket for foreign debris or damage. If debris is found, remove debris. If socket is damaged, replace the system board first.
             (Trained Service technician only) If error recurs, replace the system board.
