Check Free Memory Slots Linux
Posted : admin On 4/7/2022Here’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.
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
Checking free memory slots left hi, I was just wondering is there any way one can check how many memory slots are unused in a HP server running HP UX 11i (rp5xxx,7xxx,8xxx and SD) without going all throught those calculations 'I have that much memory, my system can support up to that much memory - it means that I can add that much more memory'. Sometimes, however, top can be a bit much for your needs. You may only need to see the amount of free and used memory on your system. For that, there is the free command. The free command displays: Total amount of free and used physical memory. Total amount of swap memory in the system. Buffers and caches used by the kernel.

Method-1: Using free Command. Free displays the total amount of free and used physical and swap memory in the system, as well as the buffers and caches used by the kernel. The information is gathered by parsing /proc/meminfo. Suggested Read: free – A Standard Command to Check Memory Usage Statistics (Free & Used) in Linux.
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
From this we can see that 8x 2048MB modules are installed – so all the slots on the motherboard are populated.
There is plenty of other useful information that can be retrieved using dmidecode, including

If your computer crashes after installing a new set of RAMs, there are few possibilities. The first possibility is likely a faulty RAM, the second possibility is hardware compatibility. More often than not if it is compatibility due to overspec or underspec, your system would not boot up and will make a beeping sound.

Ffaulty RAMs are pretty rare, almost unlikely if you bought a branded RAM such as Kingston, Samsung, Corsair, Apache and etc, this is because they performed many tests before distributing them to dealers. Based on my experience, here are some possibilities:
- Defective RAM ( Use both Windows Memory Diagnostics and Memtest86 to perform a deep scan, run twice to confirm, if both tests show the RAM is in good condition, then it is most definitely another issues. )
- Outdated Motherboard BIOS ( Update your Motherboard BIOS if it is outdated )
- Outdated drivers and chip-sets ( Update your drivers and chipsets )
- Overheating of RAM ( Use a table fan to test this )
- Faulty RAM slot ( Swap RAM between slots to see if problem continues )
- Incompatibility with your other hardware such as Asus NVidia GTX 970 Graphic Card. ( I’ve upgraded my RAM to 32GB from 16GB for my Dell XPS 8700, unfortunately, the solution to limit the RAM in Windows as shown in Reddit doesn’t work for me. Read more – GTX 970 unstable on system with 32 GB RAM or 64 GB RAM )
After much trial and error, swapping graphic cards and RAMs. I’ve discovered that my Asus Strix GTX 970 is unstable when my Dell XPS 8700 has a 32GB Kingston HyperX Fury or 24GB Kingston + Samsung RAM. It runs without problem when my system has both my old (4x4GB Samsung) and new (2x8GB Kingston) 16GB RAM installed, and with no problem when it is 32GB with my older GTX 745 graphic card. This is a very old issue, Nvidia appears to be dragging their feet or this is exclusively an Asus GTX970 problem.

↓ 01 – Windows Memory Diagnostics Tool 17 Tests Windows
This Window memory Diagnostics Tool is the the Pre-installed memory testing software available in Microsoft Windows Vista, Window 7, windows 8 or 8.1 & windows 10. The Memory Diagnostics Tool will run automatically when you restart Windows. It might take several minutes for the tool to finish checking your computer’s memory. Once the test is completed, Windows will restart automatically. If the tool detects errors, you should contact your computer manufacturer for information about fixing them, since memory errors usually indicate a problem with the memory chips in your computer or other hardware problem. Type “Mdsched” and search for the tool.
↓ 02 – Passmark MemTest86 13 Tests Windows Mac Linux
MemTest86 is the original, free, stand alone memory testing software for x86 computers. MemTest86 boots from a USB flash drive or CD and tests the RAM in your computer for faults using a series of comprehensive algorithms and test patterns. The latest version of MemTest86 supports all the current technologies, including:
- DDR4 RAM (and DDR2 & DDR3) support
- XMP – high performance memory profiles
- UEFI – The new graphical standard for BIOS
- 64bit – From version 5, MemTest86 is native 64bit code
- ECC RAM – support for error-correcting code RAM
- Secure boot – With MemTest86 being code signed by Microsoft
- Graphical interface, mouse support and logging of results to disk
- Self booting off USB or CD, without needing DOS, Linux nor Windows
- Dual booting – Will boot to V4 in BIOS and V6 in UEFI from a single flash drive
↓ 03 – Rember Unknown Tests Mac
Rember is a front-end GUI to the ‘memtest’ command line memory testing program. This application will allow the user to select the number of test loops, as well as the amount of memory to test. There is a ‘Log’ tab that will allow the user to monitor memory testing. The user can toggle a ‘verbose’ switch to limit the amount of output, and can also choose to quit Finder and other applications.
Defective memory can cause computers to malfunction, crash, and behave in a variety of ways which can sometimes baffle end users and computer technicians alike. Apple provides hardware test CDs with most of their products, and there are some third-party utilties for Mac OS X which perform memory testing. In my experience, these tools have not always been able to quickly and efficiently diagnose memory problems. Rember has been designed to simplify the testing, and diagnosis of these problems.
