我如何找到哪个内存出现CE错误？

在/var/log/kern.log：

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)

这是edac日志，内存之一有ce错误。

我已阅读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 |
    ===================================

并找到错误通道：

$ 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

并应mc0/csrow0/ch2，作为文档时，DIMM应DIMM_C0，并且可以通过发现 dmidecode：

但是我找不到这个DIMM，所以我不知道哪个内存有问题：

$ 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

有12个插槽，其中9个插槽有内存。

那么我怎么知道哪个内存有问题呢？

补充：

System Information
        Manufacturer: HP
        Product Name: ProLiant DL180 G6

您的DIMM可能有问题- Locator: PROC 1 DIMM 5F

CPU＃0Channel＃2_DIMM＃0表示：

PROC 1, 
1D,2A = Channel 0  
3E,4B = Channel 1
5F,6C = Channel 2

5F = DIMM 0
6C = DIMM 1

编辑：

当询问问题时，更多的信息总是更好的……让服务器制造商和模型可以简化此过程：

这是HP ProLiant DL180 G6 Quickspecs中的内存图：

我的建议是CPU插槽＃1中的DIMM正确...但这是HP硬件。 您无需猜测！！

您应该使用HP的管理代理，因为它们可以警告并提供有关硬件运行状况和状态的特定于平台的详细信息...
