1. Check the system event log and resolve any related problems. To view the system event log, go to
Setup Utility and select Event Logs ➙ View Smbios Event Log.
2. Make sure that:
• The DIMMs are supported by the server (see
https://serverproven.lenovo.com).
• The DIMMs are properly installed. Examine if there is any gap between the connector and the DIMM.
Remove and install the DIMM if there is any.
3. If the server comes with Lenovo XClarity Provisioning Manager Lite, go to Diagnostics ➙ Memory test
to perform diagnostics on the DIMMs. Replace the DIMM that is displayed as faulty. Otherwise, skip to
the next step.
4. Remove the DIMMs until the system reaches minimal memory requirement; then, add one DIMM and
reboot the server, and repeat the step if the problem does not recur. If the problem occurs after addition
of a DIMM, replace it.
See
“Technical specifications” on page 3 for the minimal configuration for debugging.
