Memory modules identified as failed​

Note
Each time you install or remove a memory module, you must disconnect the server from the power source; then, wait 10 seconds before restarting the server.

Complete the following procedure to solve the problem.

  1. Check and make sure the DIMM slots are intact and there is no dust or foreign objects in the DIMM slots.

  2. See Memory module installation rules and order to make sure the present memory module population sequence is supported. An unsupported memory module population sequence may cause certain memory modules to be disabled. Correcting the population and rebooting the system can resolve such issues.

  3. Swap the positions of the failed memory module and a functional one, and then restart the system to observe whether the error persists.

    • If the error continues to occur on the originally failed memory module, this strongly suggests that the module itself is defective and should be replaced.

    • If the error appears in the original error location (now occupied by the functional module), the issue is likely unrelated to the memory modules and may instead stem from the processor or processor board. Continue the following step for further troubleshooting.

  4. Swap the ​faulty processor (associated with memory errors) with a ​functional processor to determine whether the memory module issue is processor-related.

    • If the error persists in the original error location after swapping processors, this indicates a processor board-related issue. Please contact a professional technician to conduct further inspection of the processor board.

    • If the error follows the originally faulty processor after the swap, the problem is likely ​processor-related, and replacing the processor should resolve the issue.
