Action
Isolate and minimize the memory configuration. Use care when handling DIMMs.
Be sure the memory meets the server requirements and is installed as required by the server. Some
servers might require that memory channels be populated fully or that all memory within a memory
channel be of the same size, type, and speed.
If you are unsure which DIMM has failed, test each channel of DIMMs by removing all other DIMMs.
Then, isolate the failed DIMM by switching each DIMM in a channel with a known working DIMM.
Remove any third-party memory.
To test the memory, run linux stress app.
Update the BIOS to the latest version.
Reseat the DIMM.
Replace the DIMM.
