164 A change in the memory configuration occurred. This message might appear after you add or
remove memory.
Note: The server can be used with decreased memory capacity.
Action:
1. If POST error message 289 also occurred, follow the instructions for that error
message first.
2. If you just installed or removed memory, run the Configuration/Setup Utility
program; then, exit, saving the new configuration settings.
If the message appears again, shutdown the server, reseat the memory
modules, and restart the server.
3. If the problem persists, check to see if the system has isolated the problem to a
memory module:
• If the System Error light on the operator information panel is on, check to
see if the MEM LED on the diagnostic LED panel is on. If it is on, check
the DIMM Error LEDs next to the memory sockets. If a DIMM Error LED
is on, run the diagnostic program for the memory.
— If the tests fail, replace the DIMM. If the problem persists after you
replace the DIMM, call for service.
— If the memory tests do not fail, call for service.
• If no error LED is on, the error logs in the Configuration/Setup Utility
program might provide additional information on the memory error.
If the problem persists, call for service.
