Isolating and minimizing the memory configuration

When troubleshooting memory issues, sometimes it is necessary to isolate DIMMs in a minimum configuration to determine which DIMM failed.

Prerequisites
Use care when handling DIMMs.
Procedure
  1. If you are unsure which DIMM has failed, test each channel of DIMMs by removing all other DIMMs.
  2. Isolate the failed DIMM by switching each DIMM in a channel with a known working DIMM.
