linux下查看内存条数及每根内存大小的实现方法

linux下查看内存条数及每根内存大小的实现方法(推荐)

在linux系统中，查看内存条个数，及每根内存的大小，可以使用dmidecode命令。

如下：

#dmidecode | grep -A16 "Memory Device$"

输出结果：

Memory Device #存储设备
Array Handle: 0x1000 #阵列处理
Error Information Handle: Not Provided #错误信息的处理：不提供 
Total Width: 72 bits #总宽度： 72位
Data Width: 64 bits #数据宽度： 64位

然后，用free命令查看当前内存的使用情况：

# free -m 
total used free shared buffers cached
Mem: 4054 2963 1090 0 144 1272
-/+ buffers/cache: 1547 2506
Swap: 4094 0 4094
