Common Memory Event Codes

Your server may report memory events such as (but not limited to):

  • MEM0802
  • MEM6102
  • MEM6101
  • MEM5100
  • MEM5104
  • UEFI0103 - Memory initialization error on slot:
  • MEM6101 - Diagnostic warning in memory device at Check device and system configuration. (Extended ID: )
  • MEM0001 - Uncorrectable event consumed; may cause server reboot if OS cannot recover.
  • MEM9072 - Patrol scrub found uncorrectable error (not consumed); no impact unless OS uses the memory.
  • MEM6104 - Uncorrectable error; extended bytes show if the address was consumed or identified by patrol scrub.

Initial Troubleshooting Steps

Most of the above issues are resolved or accurately diagnosed by updating the firmware of specific components. Firmware updates contain fixes for known issues and enhancements, making them a critical first step towards resolution.

  1. Update the firmware of the following components:
    1. CPLD
    2. iDRAC
    3. BIOS
    Note: If the CPLD firmware is not available for the server model, then that is not an issue, proceed with the rest of the updates
    HowTo: Follow the steps in PowerEdge: How to do firmware updates for every important component
  2. Clear System event log (SEL) by following the steps in the below article.

  3.  Perform two full restarts of the server.
  4. Gather a Support Log (TSR) and check if any memory events are reported (PowerEdge: Export a SupportAssist Collection Using an iDRAC)

Advanced Troubleshooting Steps

Once the initial steps have been completed, the issue might be resolved or further troubleshooting might be required depending on the information in the TSR logs, to identify the defective component.

Upon reviewing the TSR logs, the following error messages might be identified:

  • Single Bit memory events (degraded memory) found in the logs:
    1. Turn the system off, disconnect the power, press, and hold the power button for 10 s to remove all flea power
    2. Wear Electrostatic Discharge (ESD) protection gear
    3. Remove the reported DIMM
    4. Swap the DIMM into another slot with a known good DIMM
    5. Close it and connect it to power again
    6. Turn it on
    7. Restart it two times (POST > OS > restart > POST > OS > restart)
    8. Collect a new TSR and check for memory events again
  • Multibit memory events (failed memory) found in the logs:
    1. Turn the system off, disconnect the power, press, and hold the power button for 10 s to remove all flea power
    2. Wear Electrostatic Discharge (ESD) protection gear
    3. Remove the reported DIMM
    4. Check if the machine is in a supported memory configuration, if not, remove additional DIMMs until a supported configuration is reached
    5. Close it and connect it to power again
    6. Turn it on
    7. Collect a new TSR and check for memory events again

Depending on the outcome of the advanced troubleshooting steps, a part replacement is needed for either the memory DIMM, if the memory event changed slot, or the motherboard if the memory event remains on the same slot.
