Linux Get Memory Slot Info

Sep 19, 2017 An article explaining how to check physical memory (RAM) in the Linux server. 4 different commands to get memory information from the Linux server. Checking physical memory (RAM) In this article we will see basic commands to check physical memory on a server in Linux. The number of memory devices in the results of sudo dmidecode -type 17 is equal to the number of memory slots, so the command to print the number of RAM slots is: sudo dmidecode -type 17 grep 'Memory Device' -count The results of this command will be. @azorius (and probably unimplemented) means the bios/chipset can handle 4 slots, but the board manufacturer decided not to include 2 of the possible slots the bios can support in the physical realm that is the actual MB.

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