使用CentOS 7升级服务器SuperMicro后，EDAC内存错误。这些主板，操作系统或内存模块损坏的具体错误？

SuperMicro MBD-X9DRD-EF主板上有服务器。 在一年的时间内，它在CentOS7上运行良好，一个CPU（Intel Xeon X6 E5-2620v2）和128 Gb（8×16 Gb）LVDDR（1600MHz Crucial ECC Reg RTL（PC3-12800））内存。 上个月，我们通过添加第二个CPU和额外的128 Gb内存来升级这个服务器，与现有的内存完全相同。 但是，在密集使用服务器（3-4天）之后，我们开始接收（经常）这样的错误：

[root@GBserver log]# dmesg [614781.869098] EDAC sbridge MC1: HANDLING MCE MEMORY ERROR [614781.869104] EDAC sbridge MC1: CPU 6: Machine Check Event: 0 Bank 7: 8c00004000010090 [614781.869106] EDAC sbridge MC1: TSC 0 [614781.869108] EDAC sbridge MC1: ADDR 38126a6c40 [614781.869110] EDAC sbridge MC1: MISC 14066ca86 [614781.869112] EDAC sbridge MC1: PROCESSOR 0:306e4 TIME 1473082855 SOCKET 1 APIC 20 [614782.595676] EDAC MC1: 1 CE memory read error on CPU_SrcID#1_Ha#0_Chan#0_DIMM#0 (channel:0 slot:0 page:0x38126a6 offset:0xc40 grain:32 syndrome:0x0 - area:DRAM err_code:0001:0090 socket:1 ha:0 channel_mask:1 rank:1) 

和edac-util的输出：

mc1：csrow0：CPU_SrcID＃1_Ha＃0_Chan＃0_DIMM＃0：296182更正的错误

这些错误是由主板，CPU还是操作系统故障引起的，还是我们打破了内存芯片？ 我们该怎么做？ 如何find损坏的内存模块？

• 主动进程交换，尽pipe可用内存
• 在Apache上使用SSL之后意外的内存使用情况
• AWS和RAM膨胀
• Lighttpd大上传内存消耗
• 在Windows Server 2003上安装MYSQL – 低内存使用模式
