What To Do

If a memory configuration error message displays on your BIOS screen upon power-on, you should:

  1. While the BIOS is at the F1 screen, view the SP ILOM Event Log.

    For information about how to view the SP ILOM Event log, see View or Clear the ILOM Event Log Using the Web Interface or View or Clear the ILOM Event Log Using the CLI. For information about the error codes presented in the ILOM Event Log, see IPMI Sensor Error Descriptions For X8450.

  2. Based on the information you found in the SP ILOM Event Log, you might need to:

    1. Power-off the server module and remove it from the chassis.

    2. Remove the server module cover and inspect the FB-DIMM memory configuration.

    3. To properly configure and populate the FB-DIMMs on the X8450 Server Module, follow the guidelines presented in Memory Module Configuration and Population Order
