Symptoms

This article explains how to isolate a defective memory DIMM in a Dell PowerEdge server. 


If the system is operational, run the appropriate diagnostic test. 
If diagnostics indicates a fault, follow the corrective actions that are provided by the diagnostic program.

If the system is not operational, turn off the system and attached peripherals, and unplug the system from the power source. Wait at least 10 seconds and then reconnect the system to power.

  1. Turn on the system and note the messages on the screen.
    If an error message is displayed indicating a fault with a specific memory module, go to step 10.
     
  2. Enter the System Setup and check the system memory setting.
     
  3. Turn off the system and open the system.
     
  4. Check the memory channels and ensure that they are populated correctly.
     

     

    SLN306398_en_US__1icon Note: See the system event log or system messages for the location of the failed memory. Reinstall the memory device.

     

  5. Reseat the memory modules in their sockets.
     
  6. Close the system.
     
  7. Enter the System Setup and check the system memory setting.
    If the problem is not resolved, proceed with the next step.
     
  8. Open the system.
     
  9. If a diagnostic test or error message indicates a specific memory module as faulty, swap or replace the module with a known good memory module.
     
  10. To troubleshoot an unspecified faulty memory module, replace the memory module in the first DIMM socket with a module of the same type and capacity. 
    If an error message is displayed on the screen, this may indicate a problem with one or more installed DIMM types, incorrect DIMM installation, or defective DIMMs. Follow the on-screen instructions to resolve the problem.
     
  11. Close the system.
     
  12. As the system boots, observe any error message that is displayed and the diagnostic indicators on the front of the system.
     
  13. If the memory problem is still indicated, repeat step 10 through step 13 for each memory module installed.
