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.
