系统为ubuntu20.04.6，超微x9dri-f双路主板，两颗e5 2600v2系列cpu，内存条插满。主要用来跑深度学习模型，在训练过程中经常会出现死机的现象，开启mcelog后有如下报错

 有那么几个令人在意的点，似乎是内存的问题，多方查找无法找到定位cpu12 bank9位置的方法，最后在chatgpt的帮助下找到如下指令

在我电脑上运行后得

*-memory        description: System Memory        physical id: 2d        slot: System board or motherboard        size: 208GiB        capabilities: ecc        configuration: errordetection=multi-bit-ecc      *-bank:0 .......................      *-bank:9           description: DIMM Synchronous [empty]           product: Dimm1_PartNum           vendor: Dimm1_Manufacturer           physical id: 9           serial: Dimm1_SerNum           slot: P2_DIMME2           width: 64 bits ..............................................      *-bank:14          *      *-bank:15           *

 可以看到bank9处对应我电脑的E2内存插槽，应该是内存条有问题，拔下或者更换。

有些博客给出直接

但在我的系统上无法使用

官网给出的方式之一:
