How to check the size and speed of your RAM in Windows 10
To check your installed RAM in Windows 10:
- Launch Task Manager with Ctrl+Shift+Esc.
- Click the “Performance” tab.
- Look at the capacity displayed under “Memory”.
Applies to All Windows 10 Versions
Your RAM (random access memory) is one of the major contributors to the overall performance of your PC. Programs consume RAM while they’re open, so multitasking with multiple apps requires you to have sufficient memory available.
You can check how much is in your PC using Windows 10’s Task Manager. Press Ctrl+Shift+Esc to launch the tool. Click the “Performance” tab at the top of the window. Next, click “Memory” in the pane on the left.
You can easily see how much RAM is inside your system by looking at the number displayed to the right of the “Memory” header – in this case, 32 GB. In addition, the screen shows you how much memory is currently in use. In this example, it’s 14.5 GB, or 45% of the available total.
A further useful metric is the speed of your memory. This is displayed in the bottom-right of the window. Higher memory speeds, measured in MHz, offer small performance increases. The benefits aren’t generally noticeable in everyday use, so we’d always recommend spending money on more RAM instead of faster RAM.
There’s no clear threshold that dictates when you should upgrade your RAM. Windows 10 employs a variety of techniques to make the most of the memory that is available. Consequently, an apparently high memory usage might not necessarily have a serious impact on your system.
Windows will terminate background processes and suspend apps to keep your foreground programs running. When this happens, you might find you notice to wait for apps to reload when you switch back to them. You may also find browser tabs reloading or behaving sluggishly as you switch between them. At this point, you might want to purchase additional RAM, or a higher-spec device if yours doesn’t have accessible memory slots.
