Memory problems Suggested actions
The amount of memory
displayed is less than the
amount of memory
installed. Verify that:
1. The memory modules are seated properly.
2. You have installed the correct type of memory.
3. If you changed the memory, you updated the memory configuration with the
Configuration/Setup Utility program.
4. All banks of memory on the DIMMs are enabled. The server might have
automatically disabled a DIMM bank when it detected a problem or a DIMM bank
could have been manually disabled.
Look in the POST error log for error message 289:
• If the DIMM was disabled by a system-management interrupt (SMI), replace the
DIMM.
• If the DIMM was disabled by the user or by POST:
1. Start the Configuration/Setup Utility program.
2. Enable the DIMM.
3. Save the configuration and restart the server.
• If you continue to get this error, replace the DIMM.
If the problem persists, call for service.
