Description : Multiple correctable ECC errors on a memory DIMM have been detected.

Response    : The affected page(s) of memory associated with the faulty
                    memory module maybe immediately retired by the operating
             system to avoid subsequent errors.

Impact      : The system will continue to operate in the presence of this
             fault. The memory DIMM is still in use and is not disabled.
             If the DIMM_CE_MAP_OUT policy is enabled, the memory DIMM is
             disabled on next system reboot and will remain unavailable
             until repaired. System performance may be impacted slightly
             due to retired memory pages.

Action      : Please refer to the associated reference document at
    for the latest
             service procedures and policies regarding this diagnosis.
