Information about memory modules in Linux

Recently I needed to check my memory modules info cause I wanted to add few GB's in my laptop. If you work under Linux (in my case Fedora) and need to get information about installed modules of a memory you can check it using following command under the root:

%dmidecode -t 17

If you've got an error like "command not found", install dmidecode package in your system using an distribution package manager. For RedHat unix systems this should look like:

%yum install dmidecode

What actually can dmidecode do you can find out by typing:

%man dmidecode
