用SuperMicro 7升级服务器CentOS后的内存错误。这些是主板、操作系统或内存模块损坏的具体错误吗？

Question

我在SuperMicro MBD-X9DRD-EF主板上有服务器。在这一年中，它在CentOS7上工作得很好，有一个CPU (英特尔最初的Xeon X6 E5-2620v2)和128个Gb (8x16GB)的LVDDR (1600 the关键的ECC (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，这与现有的内存完全相同。但是，在大量使用服务器(在3-4天内)之后，我们开始接收(非常频繁)这样的错误：

[root@GBserver log]# dmesg

这些错误是由主板、CPU或OS故障引起的，还是内存芯片损坏了？我们该怎么办？如何找出损坏的内存模块？

Answer 1

3周后，有大约11M纠正错误记录。看到BIOS日志后，我发现内存模块坏了。

这就是我的问题的答案。

接下来，我将删除已损坏的模块并将其替换为另一个模块。
