Memory Problems - HP ProLiant ML100 Series User Manual

Memory problems

General memory problems are occurring
Action:
•
Isolate and minimize the memory configuration. Use care when handling DIMMs ("DIMM handling
guidelines" on page 51).
Be sure the memory meets the server requirements and is installed as required by the server.
o
Some servers may require that memory banks be populated fully or that all memory within a
memory bank must be the same size, type, and speed. To determine if the memory is installed
properly, see the server documentation.
Check any server LEDs that correspond to memory slots.
o
If you are unsure which DIMM has failed, test each bank of DIMMs by removing all other
o
DIMMs. Then, isolate the failed DIMM by switching each DIMM in a bank with a known working
DIMM.
Remove any third-party memory.

•
To test the memory, run HP Insight Diagnostics (on page 40).
