De ipmitool opdracht rapporteert geen fouten op de DIMM-banken (vier DIMM's als twee banken):

ipmitool sdr entity 32 
DIMM_Bank0       | 30h | ok  | 32.0 | 23 degrees C
DIMM_Bank1       | 31h | ok  | 32.1 | 24 degrees C
DIMM_Bank2       | 32h | ns  | 32.2 | No Reading
DIMM_Bank3       | 33h | ns  | 32.3 | No Reading
 

De dmesg Uitvoer vertoont tekenen van geheugencorruptie:

Opvragen mcelog Op de volgende dagen wordt een toenemend aantal gecorrigeerde geheugenfouten weergegeven:<

Dag 1:

mcelog --client
Memory errors
SOCKET 0 CHANNEL any DIMM any
corrected memory errors:
        9 total
        9 in 24h
uncorrected memory errors:
        0 total
        0 in 24h

Dag 2:

mcelog --client
Memory errors
SOCKET 0 CHANNEL any DIMM any
corrected memory errors:
        30 total
        21 in 24h
uncorrected memory errors:
        0 total
        0 in 24h
 

De controller opvragen met behulp van de arcconf Command May Report a Bus:

arcconf getconfig 1 
Bus error

Cause

Dit duidt op een voorspellende fout van een DIMM.
