Linux Get Ram Slots

So now you need to install and lookup a command to find out such basic information as the memory type when Linux used to tell you in dmesg and the BSD’s still do. I guess ‘modern’ Linux get’s more like windows every day. Dmidecode can be used to query the motherboards DMI zone about RAM, Ram Slot(s) and Memory Controller: dmidecode -t memory is equivalent to running the 4 commands below (i.e dmidecode -t 5 -t 6 -t 16 -t 17 ).

free

free is the Unix command to know about free/used/available memory on your system:

under Gnome: hardinfo

Gnomes's System Information (Hardinfo in Menu Applications/System Tools, from package:hardinfo) has an information page on the RAM installed.

under KDE: KInfocenter

KDE's KInfoCenter (in K Menu / System / KInfoCenter Info Center, from package:kcontrol) has an information page on the RAM installed.
