Find out how much RAM your PC supports

There are a number of ways to find out how much RAM your computer can support, be it desktop or laptop, which we’ll see below.

Note: 32-bit versions of Windows support up to 4GB of RAM while this limitation does not apply to 64-bit versions. It’s a good idea to know which version of Windows your computer has before you buy extra RAM for your computer.

Check motherboard’s technical specifications

Initially, you will need to know the model of your computer’s motherboard. For desktop computers, this is easier to find because there is easier access to the inside of the computer (especially if you built it yourself) as opposed to laptops. If you do not know what the motherboard model is, then you can use Piriform’s free Speccy tool or any other equivalent tool.

Specifically for Speccy, the motherboard model appears on the Motherboard tab as you will see in the picture below.

So once you know the brand and model of the motherboard, go to the manufacturer’s website and look for the same model to see its information. You can use the search or the corresponding menus on the page. Once you have found your motherboard, take a look at its technical features where it is likely to report the total size of RAM it supports. If it isn’t written there, then download the motherboard’s manual where it will surely mention this.
