1.dmidecode

sudo dmidecode -t memory

这里也可以把查询的信息输出到特定的文件上去，下面是折腾出来的记录

这里写图片描述

个人记录
想要扩展一下笔记本电脑的内存，于是想到写这个记录的
联想笔记本电脑Y550P
DDR3 1066 2GB内存，两个内存插槽，问了一下客服，只支持window操作系统的服务，顿时表示很有压力

风暴出来其它的想法
- dmidecode命令可以实现
- System Information 服务器品牌
- Base Board Information 主板型号/主板信息
- Processor Information CPU信息/CPU型号/CPU主频
- Cache Information 硬件和CPU缓存情况
- Physical Memory Array 主板最大支持内存
- Memory Array Mapped Address 目前的内存
- On Board Device Information 显卡型号
