我在服务器中有一些失败的RAM,我运行dmidecode来弄清楚我需要用什么RAM来替换它.
服务器有6个RAM插槽,其中4个正在使用中.当我运行dmidecode时,这就是我得到的.
dmidecode 2.10
SMBIOS 2.4 present.

有谁知道为什么它会显示8个插槽,4个空而不是6个插槽,2个空？此外,但我的记录和其他工具,服务器目前有16Gb而不是8Gb.
grep MemTotal /proc/meminfo MemTotal: 16435808 kB
该板是Tyan S5372-LC,运行CentOS 5.4 x64.
此外,我的错误日志显示银行6中的错误.有没有办法确定哪个插槽库6通过：dmidecode？
EDAC MC0: CE row 0,channel 0,label "": (Branch=0 DRAM-Bank=6 RDWR=Read RAS=1755 CAS=2492,CE Err=0x2000 (Correctable Non-Mirrored Demand Data ECC))
该芯片组支持8个内存插槽. 8个实际DIMM插槽可能有管道,但只有6个连接.主板制造商可以在主板上放置8个插槽,但选择不这样做.
原文链接：https://www.f2er.com/centos/373803.html有什么说“银行6”有错误？某种服务器管理控制台？其中一个插槽可能在主板上标记为DIMM06 – 我会检查一下.
至于大小差异,您可能确实安装了4GB DIMM,但BIOS或DMI表中的错误仅将其报告为2GB DIMM.
底线：不要相信dmidecode,它不会在这里给你足够的信息.需要目视检查.
(或者,检查Tyan’s website)
