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

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 和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."

N/A

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。
