1. Reseat the DIMMs; then, restart the server.
2. Remove the lowest-numbered DIMM pair of those that are identified
and replace it with an identical pair of known good DIMMs; then,
restart the server. Repeat as necessary. If the failures continue after
all identified pairs are replaced, go to step 4.
3. Return the removed DIMMs, one pair at a time, to their original
connectors, restarting the server after each pair, until a pair fails.
Replace each DIMM in the failed pair with an identical known good
DIMM, restarting the server after each DIMM. Replace the failed
DIMM. Repeat step 3 until you have tested all removed DIMMs.
4. (Trained service technician only) Replace the system board.
