How to Check RAM Speed

How much RAM your computer has, and how fast it is – we explain how to check your RAM speed.

Your computer’s RAM is one of its most important components: it is responsible for loading and running all the software you use. So whether you are diagnosing a problem or want to improve, know exactly how much and how fast memory is important.

How much RAM is on my computer?

The easiest way if you have Windows 10 is to right-click on the taskbar and select Task Manager from the menu. If in compact mode, click More details, then click on the Performance tab.

Click Memory and you will see how much your computer is in the upper right corner.

If you have an older version of Windows, press Windows Key + R to bring up the Run command.

Type dxdiag in the Open field and click OK. In the window that appears you will be able to see how much memory is inside your PC.


How do I check my RAM speed for Windows 10?

Windows makes it difficult to see your RAM’s clock speed, so for this we need to use a third-party program: CPU-Z.

Install CPU-Z and it will run your system analysis, then present lots of useful information – including RAM speed.


Click the Memory tab to find lots of information about your computer’s memory. What you’re looking for is the top entry: ‘DRAM Frequency’.

As you will see in our screenshot, our RAM is 534MHz, but because it is DDR RAM (Double Data Rate) we multiply that number by two to get the final 1068MHz.

You can also enter your computer’s BIOS and see the RAM speed there. If you already know what speed your RAM is running, you will know whether it is at the correct speed or not.

If you don’t know, then you might have to look at the memory stick yourself to find a brand and model, then search online to find out the specifications. Quite often, RAM is designed to run faster than the JEDEC presed standard will run slower than it is capable of, so you might have to enter the BIOS and manually adjust the speed (and other timings) to make it run at the right speed.

When adding more RAM in a free memory slot, it’s a good idea to get a suitable stick if you can. If not, buy RAM that matches your current memory specifications.
