  • The memory limits are exceeded for the server.

  • The DIMM is not properly seated.

  3. Verify that you have not exceeded the memory limits of the server or operating system.
  4. Verify that the DIMM is seated properly.
  5. Install the DIMM into a known working server to verify that the DIMM works.
