How to identify the installed Memory / RAM.
Many people simply use free, which is available on every Debian system, to list the quantity of RAM installed (detected). Gnome users can install and use the hardinfo. KDE user can use kinfocenter.
free is the Unix command to know about free/used/available memory on your system:
Gnomes's System Information (Hardinfo in Menu Applications/System Tools, from package:hardinfo) has an information page on the RAM installed.
KDE's KInfoCenter (in K Menu / System / KInfoCenter Info Center, from package:kcontrol) has an information page on the RAM installed.
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)
You can also check information about RAM (like speed, type, etc) using lshw (from package lshw).
