组网及说明

Advisory: ProLiant DL3X5 Gen11 Server - Systems With AMD EPYC 4th Gen Processors May Experience an Uncorrectable Error\Uncorrectable Machine Check During Runtime, or System Unresponsiveness at Memory Initialization During Boot

文档ID:a00156999en_us    Last Updated: 2026-02-23

 

影响范围

如下服务器搭载AMD 4th Generation EPYC 处理器:

  • HPE ProLiant DL325 Gen11
  • HPE ProLiant DL345 Gen11
  • HPE ProLiant DL365 Gen11
  • HPE ProLiant DL385 Gen11

问题描述

 

在某些情况下,HPE ProLiant DL3X5 Gen11 服务器可能会遇到以下问题:

             在启动过程中,出现内存初始化错误,导致显示“不支持的 DIMM 配置”,该错误会在启动期间显示并记录到 IML日志中。

或者

             在运行期间,在高负载下出现不可纠正内存错误,导致Uncorrectable Machine Check,该异常会被记录到 IML 中。

以下是 DIMM 初始化时服务器无响应情况的报错示例:

 

"41: DIMM Initialization Error-processor 1 DIMMs 1. The identified memory channel could not be properly trained and has been mapped out. Major Code 0001088, Minor Code 00000002."

"42: Unsupported DIMM configuration detected=Processor 1 violates DIMM Population rules. Action: consult the user guide for more information on supported configurations and population rules."

如下是在高负载情况下服务器出现的Uncorrectable Memory Error Uncorrectable Machine Check error 示例:

"Uncorrectable Machine check exception. Error was detected on Processor 2. Uncorrectable machine check exception extended registers. Reseat the processor. Replace the failed DIMM."

过程分析

N/A

解决方法

如果出现此问题,无需更换硬件。升级BIOS (A55/A66)固件版本到3.00_02-06-2026 或更高。
