Linux Find Out Memory Slots

For even more info, go to File- System Report. In the new window that appears, click Memory in the list on the left. It will show you the number of slots and what's in each one. In the below screenshot, there is one empty bank. It's the one with the Size, Type, Speed, and Status as Empty. Apr 07, 2018 Linux FAQ: How can I find Linux processor and memory information? (Also written as, How can I find Linux CPU information?, How can I find Linux RAM information?) Back to top How to show the Linux CPU/processor. To see what type of processor/CPU your computer system has, use this Linux command: cat /proc/cpuinfo. @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.

Linux is one of the most popular open source operating system and comes with huge set of commands. The most important and single way of determining the total available space of the physical memory and swap memory is by using “free” command.

The Linux “free” command gives information about total used and available space of physical memory and swap memory with buffers used by kernel in Linux/Unix like operating systems.

This article provides some useful examples of “free” commands with options, that might be useful for you to better utilize memory that you have.

1. Display System Memory

Free command used to check the used and available space of physical memory and swap memory in KB. See the command in action below.

2. Display Memory in Bytes

Free command with option -b, display the size of memory in Bytes.

3. Display Memory in Kilo Bytes

Free command with option -k, display the size of memory in (KB) Kilobytes.

4. Display Memory in Megabytes

To see the size of the memory in (MB) Megabytes use option as -m.

5. Display Memory in Gigabytes

Using -g option with free command, would display the size of the memory in GB(Gigabytes).

6. Display Total Line

Free command with -t option, will list the total line at the end.

7. Disable Display of Buffer Adjusted Line

By default the free command display “buffer adjusted” line, to disable this line use option as -o.

8. Display Memory Status for Regular Intervals

The -s option with number, used to update free command at regular intervals. For example, the below command will update free command every 5 seconds.

9. Show Low and High Memory Statistics

The -l switch displays detailed high and low memory size statistics.

10. Check Free Version

The -V option, display free command version information.

If you need a quick way to find out how much RAM your Linux system supports or to determine the number of DIMM slots available, you can use a command line tool called 'dmidecode'.

To find out the maximum RAM capacity and the number of RAM slots available, use the following command:

Linux Find Out Memory Slots Without

The output should look something like this:

The 'Maximum Capacity' is the maximum RAM supported by your system, while 'Number of Devices' is the number of memory (DIMM) slots available on your computer.

To see complete memory information, including the info above along with currently installed memory information (RAM speed, size, etc.), use:

Here's an example output for the command above:

Memory Slots Available

You can also use lshw (among others) for this (firstly, install it; in Ubuntu: 'sudo apt-get install lshw):

It's important to note that Dmidecode reports system hardware information as described in the BIOS and does not scan your hardware, so in some cases the output can be wrong. Running dmidecode on my Dell XPS L702X non-3D laptop, the output says my system should have 4 RAM slots but in fact there are only 2 and only the 3D version of my laptop can have 4 RAM slots (and by the way, there are some Windows applications reporting the same thing), however, the command is accurate about it supporting 16 GB of RAM.
