Check Ram Speed and Type on Linux
How to check the memory speed without opening the computer case? An easy way to do that is using biosdecode command line utility. Dmidecode is a tool or dumping a computer’s DMI (some say SMBIOS) table contents in a human-readable format. The output contains a description of the system’s hardware components, as well as other useful pieces of information such as serial numbers and BIOS revision. This command works under Linux, UNIX and BSD computers.
Type the following command in a shell with super user privilege
dmidecode --type 17
will give you the memory infomation like this
SMBIOS 2.5 present. Handle 0x1100, DMI type 17, 27 bytes.
