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

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
