Linux 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

dmidecode | grep  -P  -A5  "Memory\s+Device" | grep Size | grep -v Range 

        Size: 16384 MB

Linux 查看内存支持的最大内存容量

dmidecode | grep -P  'Maximum\s+Capacity'       
 Maximum Capacity: 1536 GB

Linux 查看内存的频率

dmidecode | grep -A16 "Memory Device" | grep "Speed"

        Speed: 1600 MHz (0.6 ns)
        Speed: Unknown
