Linux Command Memory Slots

Here’s a useful way of finding out how many memory slots are occupied on the motherboard of a machine without removing the cover, as well as how much installed physical memory is supported.

We can use the dmidecode command to reveal your systems DMI table, which contains details of the systems hardware.
IIRC VmPeak is the maximum total memory usage including virtual memory, while VmHWM is the peak RAM usage. So if you want to know the total amount of memory your program has asked for, use VmPeak; if you want to know how much of your actual RAM it has ever used at a given time, use VmHWM. – erobertc Feb 26 ’19 at 18:53. The first command is free. This is the simplest command to check your physical memory. This command is mainly used for checking RAM and SWAP on the system. Using different switch you can change the byte-format of output. 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 one integer number equal to the number of RAM slots.
There are a whole load of DMI types we can look at – a full table of those at the end of this article.
In this particular case, we are interested in memory – type 16 ‘Physical Memory Array’ will show us how much memory is supported and DMI type 17 will reveal details of currently installed memory.
So, first off:-
dmidecode -t 16
Maximum Capacity shows us the maximum amount of memory can be installed in the machine. Number of devices tells us how many slots there are on the motherboard – in this case, 8.
Now we can interrogotate DMI type 17 – ‘Memory Device’ to show us details of installed memory
dmidecode -t 17
Each module installed will be listed with the the information given above. If we just want to know how many modules are installed and what size they are, we only really need the Size: – so we use grep
dmidecode -t 17 | grep Size

There is plenty of other useful information that can be retrieved using dmidecode, including
