kernel: [13291329.657499] EDAC MC0: 48 CE error on CPU#0Channel#2_DIMM#0 (channel:2 slot:0 page:0x0 offset:0x0 grain:8 syndrome:0x0)
Questo è edac
log, uno della memoria ha un ce
errore.
Ho letto edac doc
Dual channels allows for 128 bit data transfers to the CPU from memory.
Some newer chipsets allow for more than 2 channels, like Fully Buffered DIMMs
(FB-DIMMs). The following example will assume 2 channels:
Channel 0 Channel 1
===================================
csrow0 | DIMM_A0 | DIMM_B0 |
csrow1 | DIMM_A0 | DIMM_B0 |
===================================
===================================
csrow2 | DIMM_A1 | DIMM_B1 |
csrow3 | DIMM_A1 | DIMM_B1 |
===================================
e trova il canale di errore:
$ grep "[0-9]" /sys/devices/system/edac/mc/mc*/csrow*/ch*_ce_count
/sys/devices/system/edac/mc/mc0/csrow0/ch0_ce_count:0
/sys/devices/system/edac/mc/mc0/csrow0/ch1_ce_count:0
/sys/devices/system/edac/mc/mc0/csrow0/ch2_ce_count:144648966
/sys/devices/system/edac/mc/mc0/csrow1/ch0_ce_count:0
/sys/devices/system/edac/mc/mc1/csrow0/ch0_ce_count:0
/sys/devices/system/edac/mc/mc1/csrow0/ch1_ce_count:0
/sys/devices/system/edac/mc/mc1/csrow0/ch2_ce_count:0
/sys/devices/system/edac/mc/mc1/csrow1/ch0_ce_count:0
/sys/devices/system/edac/mc/mc1/csrow1/ch1_ce_count:0
e dovrebbe essere mc0/csrow0/ch2
, come il documento, il DIMM dovrebbe essere DIMM_C0
, e può essere trovato da dmidecode
:
Ma non riesco a trovare questo modulo DIMM, quindi non so quale memoria abbia un problema:
$ dmidecode -t memory | grep 'Locator: PROC'
Locator: PROC 1 DIMM 2A
Locator: PROC 1 DIMM 1D
Locator: PROC 1 DIMM 4B
Locator: PROC 1 DIMM 3E
Locator: PROC 1 DIMM 6C
Locator: PROC 1 DIMM 5F
Locator: PROC 2 DIMM 2A
Locator: PROC 2 DIMM 1D
Locator: PROC 2 DIMM 4B
Locator: PROC 2 DIMM 3E
Locator: PROC 2 DIMM 6C
Locator: PROC 2 DIMM 5F
Ci sono 12 slot e 9 slot hanno memoria.
Quindi, come posso sapere quale memoria ha problemi?
