How to increase VRAM in Windows 10 using these 2 methods

Don’t know how to access BIOS on Windows 10? Check out our step-by-step guide!
2. Increase dedicated VRAM via Registry Editor (integrated Intel GPU’s)
- Press Windows key + R to open Run, and type regedit. Hit Enter.
- Navigate to
HKEY_LOCAL_MACHINESoftwareIntel
- In the side-panel, right-click the Intel folder and select New > Key, then name it GMM.
- In the side-panel, under Intel, a new GMM folder should appear. With the GMM folder selected, in the right section on an empty space right-click and create a New > Dword (32-bit).
- Name it DedicatedSegmentSize.
- Now double-click the DedicatedSegmentSize, under Base choose Decimal.
- Under Value data type a number between 0 and 512. That’s the amount of RAM you can allocate in megabytes, and it should appear in Adapter Proprieties.
- Save and Restart PC.
Usually, the system automatically adjusts the amount of VRAM needed by any application at any given time. In some cases, when you need just a little bit more to run an app or a game, you can fake a VRAM increase through Registry Editor.
Ever wondered how much RAM can Windows 10 handle? You wouldn’t believe it
Increasing the VRAM in Windows 10 through BIOS or Registry Editor is a nifty solution that may come in handy sometimes, but if you are looking for real horsepower under the hood, then we suggest to buy a dedicated graphics card.
If you’re rocking a dedicated GPU, even an older one, it’s way more likely to be satisfied with the result over any brand-new integrated one.

- How do I allocate more RAM to my graphics card Windows 10?
Open the Registry Editor and create a new entry as we’ve explained in this guide.
- How can I increase my total graphics memory?
You can either increase it by sharing some of you RAM with your graphics card as shown in this guide, or by upgrading your GPU to a model with more VRAM.
- Does increasing VRAM increase FPS?
It depends on your use case. If you are playing a game on a high-resolution monitor, then your VRAM will fill and the GPU will start writing to slower memory, therefore lowering your FPS dramatically. In this case, the answer is yes, increasing the amount of VRAM available will increase your FPS but only if you have enough RAM to cover the memory needs.
