Want to use your hard drive as RAM?

If you are using an old computer with less than 4 GB of RAM, you probably need to supercharge your PC by setting up virtual memory in Windows using your HDD.

A few years ago, I had an old Windows computer with only 2 GB of RAM. This sucked, to be honest. However, I was able to still run my ordinary tasks pretty well. 🙁

But when it came to multitasking, it was horrible. But using virtual memory allocation in Windows, I was able to boost my performance a bit more. This guide is for all Windows users.

This virtual memory is called paging memory which acts as a slower version of RAM. However, you will see no change in your RAM count. It’s just telling Windows to say your free space to run tasks and to make things faster.

How to Use Hard Drive as RAM on Windows?

This might sound complicated but believe me, it’s as easy as baby-steps. You just need to follow the steps I have mentioned. There’s a controversy about how much virtual memory should I set or allocate.

There’s nothing to worry about, it’s very simple. I’m running Windows 10 on my PC. But this works across all Windows versions.

I have tried this in Windows 7 and 8 before, the procedure is just identical. I would recommend this to anyone with less than 4 Gigs of RAM. 😀

How much Virtual Memory Should You Set?

This is a controversial question in many forums.  The thing is, you should let Windows manage your paging memory and not worry about it unless you have only 2 GB of RAM like I had back then.

I have 16 GB RAM on my computer and mine is automatically managed by Windows. But in your case, you need to follow the steps written below. 😉

If your RAM is 2 GB, I would recommend doing with 2 GB of paging memory. But if your RAM is 4 GB, I would possibly go with 4 GB of paging memory. 😉

Using Hard Drive as RAM (Free Space)

This is the step-by-step tutorial to turn your free hard drive space into paging memory. This will make your computer faster but not too dramatically. So, don’t expect a big bump in performance. 🙂

If you’re using an SSD, I wouldn’t recommend setting your own virtual memory allocation and just set to automatic for optimal results.

Open Windows 10 Properties, Windows properties

These are the steps to set virtual memory in Windows computer. 

  1. Go to Windows Properties (screenshot above).
  2. Click on Advanced System Settings.
  3. Click on the Advanced tab.
  4. Under Performance, click Settings.
  5. Go to the Advanced Tab.
  6. Click on Change.
  7. Uncheck ‘Automatically manage paging file size for all drives’.
  8. Choose any drive, I prefer choosing a drive you don’t use very often.
  9. Set your recommended paging memory and click on Set.
  10. Restart your PC.

As you can see on the screenshot just above. I’m using 2921 GB as recommended by Windows 10. I have 16 GB of RAM, so I really don’t need paging memory to help me carry on any task. 😉

This is how you can use your hard drive as virtual RAM. I used this a lot and this helped slightly if not dramatically. This will make your system feel a bit more responsive and faster.

I have also written a guide on improving your WiFi’s signal which you should read if you have a slow internet connection. That’s how you boost your computer experience- faster internet and faster computer.


This is an easy to follow guide on increasing your RAM by allocating virtual memory. For instance, this will boost your performance at least by 20% if you’re lucky.

However, I would recommend at least 4 GB of RAM. If I was below that number, I would opt for an upgrade here.

This is how simple it is to upgrade your RAM for free using paging memory. As I already said, this is not going to increase your RAM count, but Windows will start using paging memory to run programs just like a RAM. 😛

I’m soon going to write a guide on how to turn your USB drive to RAM. So, be sure to subscribe to the newsletter.
