关于dell x86架构服务器报错：EDAC MC1: CE row 0, channel 0, label "CPU_SrcID#1_Channel#1_DIMM#0

1、查看messages，dmesg发现有许多关于EMC的报错，如下：

EDAC MC1: CE row 1, channel 0, label "CPU_SrcID#1_Channel#1_DIMM#1": 6317 Unknown error(s): memory read on FATAL area OVERFLOW: cpu=1 Err=0001:0092 (ch=2), addr = 0x7fc3afe40 => socket=1, Channel=1(mask=2), rank=4

EDAC MC1: CE row 2, channel 0, label "CPU_SrcID#1_Channel#2_DIMM#0": 5793 Unknown error(s): memory read on FATAL area OVERFLOW: cpu=1 Err=0001:0092 (ch=2), addr = 0x546da78c0 => socket=1, Channel=2(mask=4), rank=0

EDAC MC1: CE row 3, channel 0, label "CPU_SrcID#1_Channel#2_DIMM#1": 5017 Unknown error(s): memory read on FATAL area OVERFLOW: cpu=1 Err=0001:0092 (ch=2), addr = 0x696e5cbc0 => socket=1, Channel=2(mask=4), rank=5

EDAC MC1: CE row 1, channel 0, label "CPU_SrcID#1_Channel#1_DIMM#1": 3525 Unknown error(s): memory read on FATAL area OVERFLOW: cpu=1 Err=0001:0092 (ch=2), addr = 0x74e70c240 => socket=1, Channel=1(mask=2), rank=4

2、找出错误的DIMM，如下分别是cpu0，cpu1上8根内存条报错，count不为0表示有错误

mc代表第几个cpu，csrow内存通道，ch第几个内存

[root@localhost ~]#  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/csrow1/ch0_ce_count:0
/sys/devices/system/edac/mc/mc0/csrow2/ch0_ce_count:0
/sys/devices/system/edac/mc/mc0/csrow3/ch0_ce_count:0
/sys/devices/system/edac/mc/mc1/csrow0/ch0_ce_count:21248125
/sys/devices/system/edac/mc/mc1/csrow1/ch0_ce_count:11360507
/sys/devices/system/edac/mc/mc1/csrow2/ch0_ce_count:18691380
/sys/devices/system/edac/mc/mc1/csrow3/ch0_ce_count:9044537

 dmidecode -t memory 可查看内存详细信息
