1、Linux查看内存的详细信息

[root@c0235 ~]# dmidecode --type memory

# dmidecode 2.10

2、查看内存的插槽数,已经使用多少插槽.每条内存多大，已使用内存多大

[root@c0235 ~]# dmidecode --type memory|grep -i size

Size: 2048 MB

Size: 2048 MB

Size: 2048 MB

Size: 2048 MB

Size: No Module Installed

Size: No Module Installed

Size: 2048 MB

Size: 2048 MB

Size: 2048 MB

Size: 2048 MB

Size: No Module Installed

Size: No Module Installed

这个命令也可以，只是复杂些

[root@c0235 ~]# dmidecode|grep -P -A5 "Memory\s+Device"|grep Size|grep -v Range

Size: 2048 MB

Size: 2048 MB

3、Linux 查看内存频率

[root@c0235 ~]# dmidecode --type memory|grep -i speed

Speed: 266 MHz

Speed: 266 MHz

Speed: 266 MHz

Speed: 266 MHz

Speed: 266 MHz

Speed: 266 MHz

Speed: 266 MHz

Speed: 266 MHz

Speed: 266 MHz

Speed: 266 MHz

Speed: 266 MHz

Speed: 266 MHz

4、Linux 查看内存支持的最大内存容量

[root@c0235 ~]# dmidecode|grep -P 'Maximum\s+Capacity'

Maximum Capacity: 65024 MB
