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're diagnosing problems or looking to upgrade, knowing exactly how much and how fast is that memory is important.
How much RAM is in my computer?
Press the Windows Key + R to bring up the Run command.
Type dxdiag in the Open field and click OK. In the window that pops up you'll be able to see how much memory is inside your PC.
How fast is your computer's RAM?
Windows makes it difficult to see the clock speed of your RAM, so for this we need to resort to a third-party program: CPU-Z.
Install CPU-Z and it will run an analysis of your system, then serve up lots of useful information - including RAM speed.
Click the Memory tab to find a bunch of information about your computer's RAM. The one you're looking for is the top entry: ‘DRAM Frequency’.
As you'll see in our screenshot our RAM is 534MHz, but because it's dual-channel we multiply that by two to get a final figure of 1068MHz.
