本文介绍了一种通过服务器日志信息来定位具体故障内存条的方法。通过解析内核日志中的错误信息并结合dmidecode命令获取的内存布局，确定了故障内存的具体位置。

已发现2个内存错误，应用名称（kernel:）,日志内容(hangzhou-jishuan-DDS0248 kernel: sbridge: HANDLING MCE MEMORY ERROR hangzhou-jishuan-DDS0248 kernel: EDAC MC0: CE row 5, channel 0, label CPU_SrcID#0_Channel#3_DIMM#1:1 Unknown error(s): memory scrubbing on FATAL area : cpu=0 Err=0008:00c1 (ch=1), addr = 0x1c9bea000 = socket=0, Channel=3(mask=8), rank=5)

如何判断是第几条内存？

获取服务器内存信息（此信息可以在报修的时候提供给硬件厂商工程师，记得告诉他们仅供参考）。

shell命令：dmidecode | grep -A 9 -B 6 DIMM | grep Bank
