Complete the following steps:
1. Check Lenovo support site for an applicable service bulletin or firmware update that applies
to this memory error.
2. 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 580A4 event denoting detected change in DIMM
population that could be related to this problem.)
3. If no problem is observed on the DIMM connectors and the problem persists, replace the DIMM
identified by LightPath and/or event log entry.
4. If problem re-occurs 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. (check
service information for this product/Install guide for population requirements for sparing/paring
modes). If problem follows a moved DIMM to a different memory channel, replace that DIMM.
5. (Trained service technician only) Remove affected Processor and inspect Processor socket pins
for damaged or mis-aligned pins. If damage is found, or this is an upgrade Processor, replace the
system board. If there are multiple Processor’s, swap Processor’s to move affected Processor to
another Processor socket and retry. If problem follows the affected Processor (or there is only
one Processor), replace the affected Processor.
6. (Trained technician only)If problem stays with the original DIMM connector, re-inspect DIMM
connector for foreign material and remove, if found. If connector is damaged, replace system
board
