Virtual memory plays an important role in improving performance and multitasking on modern computers. It not only keeps heavy applications running smoothly, but also helps the system make better use of its resources, especially on a machine with a limited amount of RAM. Understanding how virtual memory works and how to manage it well lets you get the most out of your device, and cuts down on slowdowns and stuttering when you run software that demands a lot of resources.
What Is Virtual Memory?
You may be wondering exactly what virtual memory is.
To understand it, you first need to know what RAM and your hard drive each do. In short, the hard drive stores your files, photos, games, music, and so on, while RAM holds information and data for specific programs.
Virtual memory is also called a paging file or swap file, and it gives your system a temporary extension of its RAM. It does this by using part of your hard drive to expand RAM.
That said, virtual memory is not unlimited, and in the end you will still have to buy more RAM 🙂
Microsoft recommends setting virtual memory to 3 times the amount of RAM in your computer, or 4GB, whichever is higher, to keep the system running stably.
By default, Windows 11 calculates and manages virtual memory automatically, but this guide will show you how to change it if your computer is not meeting your needs.
Step 1: Open Windows 11 Settings by pressing Win + I.
Step 2: In the System window, scroll down and select About.
Step 3: Click Advanced system settings.
Step 4: A new window will appear. Select Settings as shown in the image.
Step 5: Click the Advanced tab.
Step 6: Click Change.
Step 7: Uncheck Automatically managed paging file size for all drives.
Step 8: Click Custom size and enter values in the Initial size and Maximum size boxes.
Step 9: That's it. Click Set, then OK.
Increasing virtual memory is not a long-term fix, and the best solution is still to upgrade your computer's RAM. Still, I hope this article helps you work around some of the problems your computer is having for now, so you can keep working.
