How To Increase Dedicated VRAM On Windows 10

Get more out of your GPU by doing some little tweaks. Here is a super simple guide on how to increase dedicated VRAM on Windows 10.

A lot of today’s most basic tasks on a computer require some type of graphics card. Watching or editing videos, playing games, and even using a word processor.

However, some tasks are more demanding than others and integrated GPUs have a hard time keeping up. This is especially true for iGPUs that lack enough VRAM (Video Random Access Memory).

Fortunately, there is a way you can increase VRAM on Windows 10. Here’s how you can do that.

What Is VRAM And Why Do You Need More Of It?

It is important to learn what VRAM is to determine whether it will really help you with your issues.

Video Random Access Memory is memory dedicated to the graphics card used to store important graphics-related data. This makes graphics processing significantly smoother and responsive. This leads to a better framerate average in video games and can get rid of stuttering.

This also means that the GPU won’t hog system RAM which can further smooth your experience in watching videos or even gaming.

In some video game titles, there is a minimum VRAM requirement. So, even if your GPU is powerful enough to run it, if you don’t have enough VRAM, it won’t even start.

Lack of VRAM can also be the cause of stuttering and frequent FPS DROPS.

Check How Much VRAM You Have

Let’s check exactly how much VRAM you have and by how much you’ll need to increase it.

  1. Right-click on your desktop and select Display Settings
    PC Display Settings
  2. Scroll down to the bottom to find Advanced display settings.

  3. From there navigate to Display adapter properties for Display #.
  4. This should open a new window and you should be able to see exactly how much VRAM you have under Total Available Graphics Memory.

Increasing VRAM

There are a couple of ways you can increase the VRAM. You could either trick the game into thinking that the GPU has VRAM than it really has which will force the game to start. Or, you can allocate part of your system’s memory (RAM) to VRAM.

Increasing Dedicated VRAM Through BIOS

The only way you can truly increase your GPU’s VRAM is through your computer’s BIOS.

Keep in mind, different laptop/motherboard brands have different BIOS. It is possible that your specific model does not have the option to allocate system RAM to VRAM.

  1. Shut Down your computer and power it on again.
  2. To enter BIOS, you will need to click the appropriate button during the boot-up sequence. The most often keys used to enter BIOS are Delete, F2, F9, or F10.
  3. Once you’ve entered the BIOS, look for Video (or Graphics) settings. Under this category of settings, you should be able to find the option VGA Share Memory Size or DVMT (Dynamic video memory technology).
  4. There should be a couple of choices under this option. Choose the appropriate amount of RAM you want to allocate to VRAM. Usually, the choices are between 32MB and 512MB.
  5. Save your BIOS changes and restart the computer.

And you are done! With your next boot, your GPU should have more VRAM available. Try out the game that gave you an issue and see how it performs.

If it still gives you that same issue, let’s try tricking it.

Increasing Dedicated VRAM With Regedit

To force Windows 10 to report more VRAM than it really has, we’ll need to use the Registry Editor or regedit.

  1. To access regedit, either use the Windows key + R shortcut or right-click Start and click Run.
  2. Now type regedit and hit Run.

  3. In Registry Editor navigate to HKEY_LOCAL_MACHINE\SOFTWARE\Intel.
  4. Right-click the Intel folder, click New -> Key, and name the new folder GMM.

  5. Select the new GMM folder, right-click on the empty space on the right side of Registry Editor, and New -> DWORD (32-bit) Value.
  6. Right-click the newly created value and rename it to DedicatedSegmentSize.
  7. Now double-click it to edit it. Under Value data add a value between 0 and 512. The value you add is how much VRAM Windows 10 will report. Also, make sure the Decimal option is selected under Base.

To save these changes, you may have to restart your computer. After the restart, you should try starting the game. The game now should run. From there, optimize the game’s settings for better performance. To reduce VRAM usage, we recommend lowering the in-game resolution.

Upgrade Your Dedicated GPU

If you’re still having performance issues with your game, unfortunately, there is no other trick you could try as a solution.

The only other solution would be to physically increase and the only way to do that is by upgrading your hardware. Specifically upgrading the GPU. Unfortunately, upgrading and installing a GPU is neither easy nor cheap. However, it’s the only solution left.

And that’s it! We hope this article was informative enough to help you increase the dedicated VRAM on Windows 10.
