Description

This guide helps evaluate ECC memory errors and determine if hardware replacement or monitoring is needed based on error frequency and system impact

Resolution

ECC correctable errors occur when memory modules detect and automatically fix single-bit data corruption. Occasional errors are normal, but frequent errors may indicate failing memory modules or environmental issues.

ECC correctable errors represent a threshold overflow for a given Dual In-line Memory Modules (DIMM) within a given timeframe.

  • if there is no catastrophic issue (Purple Screen Of Death (PSOD) or unexpected restart), and the correctable ECC error including Adaptive Double Device Data Correction (ADDDC) error that is less than 10 events within every 24 hours for each DIMM location is within threshold limit, so the recommendation is to monitor for any recurrence of ECC error each DIMM location that triggers the event
  • If there is a catastrophic issue (Purple Screen Of Death (PSOD) or unexpected restart), and the correctable ECC error including Adaptive Double Device Data Correction (ADDDC) error that are more than 10 events within every 24 hours for each DIMM location, it is recommended to re-seat each DIMM location by following the steps below:
    1. Safely Power OFF the system and remove the AC power cable
    2. Identify the DIMM location to re-seat, refer to Technical Product Specifications for your server platform to identify DIMM location
    3. Re-seat the identified DIMM(s)
    4. Insert AC power cable and power ON the system
    5. Observe for 24 hours for any recurrence of ECC error
    6. If the ECC error persists with the same DIMM location that was re-seated, then generate and send SEL and Debug logs, both generated from the BMC Web Console and send to Intel Customer Support
Notes

The Error Correction Code (ECC) errors are self-correcting. Depending on the Reliability Availability Serviceability (RAS) configuration of the memory, the Integrated Memory Controller (IMC) may take the affected DIMM offline.

For different Intel server platforms, there are some differences in their event definition, refer to System Event Log Troubleshooting Guide for your server platform

Intel recommends to download and update the system BIOS to the latest available version for your server platform.
