Memory Problems - HP ProLight Server Troubleshooting Manual

Memory problems

General memory problems are occurring
Action:
Isolate and minimize the memory configuration.
Be sure the memory meets the server requirements and is installed as required by the server.
Some servers may require that memory banks be fully populated or that all memory within a
memory bank must be the same size, type, and speed. Refer to the server documentation to
determine if the memory is installed properly.
Check any server LEDs that correspond to memory slots.
If you are unsure which DIMM has failed, test each bank of DIMMs by removing all other
DIMMs. Then, isolate the failed DIMM by switching each DIMM in a bank with a known working
DIMM.
Remove any third-party memory.
Run HP Insight Diagnostics (on page 61) to test the memory.
