If your hardware has been around for a bit, you can be pretty sure of the accuracy. With bleeding edge of hardware, you’ll find it may be less accurate. Y ou can use it to learn a great deal about your RAM.Īs I mentioned above, it’s not necessarily going to be 100% accurate. You can even see the size, number of slots, location, vendor. You can see if you have the same number of devices as you have slots. If you want, you can then scroll down and it will show you what RAM is installed.

So, from that, we can determine the number of RAM slots is equal to two. Ah ah ah ah! Oh how I love to count things! On my laptop, the output looks like this: The answer is two. The line that is important is, “Number of Devices”.

With your terminal open, enter the following command: If you don’t know how to open the terminal, you can do so with your keyboard – just press CTRL + ALT + T and your default terminal should open. On a scale of 1 to 10, I’d say this is a solid 2 – meaning even a rank beginner can follow along. In a previous article we used it with some success, and we’ll be using it again today, this time to determine the number of RAM slots available to you. While dmidecode has partially been covered previously, it defines itself as:Īnd dmidecode is a pretty handy tool. Hardware manufacturers aren’t always as nice to Linux users as they could be, so there’s some risk of bad information – or wrongly interpreted information.

It pulls its data from tables in the DMI (SMBIOS) and presents them to you. While dmidecode isn’t guaranteed to be 100% accurate, it’s usually pretty close. Well, you can do all that and you can do it all with just a single command. It’s actually a pretty easy task, consisting of just a single command.īut, wait! There’s more! You may want to know than how many RAM slots you have, you may want to know a lot more about the RAM you have already installed, how many slots are filled, if your RAM has ECC (error correction), the speed, the quantity of RAM per stick, etc… Today’s article is going to show you how to determine the number of RAM slots without actually opening up your case.
