Server fails to recognize new memory

Symptom

The server does not recognize new memory installed on the server.

Cause
  • The memory is not supported on this server.
  • The memory is not installed according to the server requirements.
  • The memory limits are exceeded for the server.
  • The processor is not supported on the server.
  • The memory is not installed or seated properly.
Action
  1. Be sure that the memory is the correct type for the server.

    For a list of supported options, see the QuickSpecs on the Hewlett Packard Enterprise website (https://www.hpe.com/info/qs).

  2. Be sure that the memory is installed according to the server requirements.
  3. Be sure that you have not exceeded the memory limits of the server or operating system.
  4. Be sure the server supports the number of processor cores.

    Some server models support only 32 cores and this might reduce the amount of memory that is visible.

  5. Be sure that no Event List error messages are displayed in the IML.
  6. Be sure that the memory is seated properly.
  7. Be sure that no conflicts are occurring with existing memory. Run the server setup utility.
  8. Test the memory by installing the memory into a known working server.

    Be sure that the memory meets the requirements of the new server on which you are testing the memory.

  9. Update the system ROM to the latest version.
  10. Replace the memory.
