How To Increase Dedicated Video RAM (VRAM) on Windows 11


Video Memory (or VRAM) was developed to solve the problem of stuttering frame rates while rendering graphics. Frames are only supplied to the display as they become available, so if the graphics processing unit (GPU) can’t render them quickly enough, then, CPU has to grab the remaining frames from VRAM, which is a part of GPU. Because you can’t save that picture indefinitely, the new frame must replace the previous one when it becomes available. The cycle is quick and constant, ends up going undetected by the observer.

It seems that you’re facing some issues regarding screen stuttering or some of your system requirements are inadequate to run some programs such as Photoshop, After Effects, Blender, etc, so you want to increase the VRAM to stop the error messages from appearing in the incompatible programs.

By the end of this article, you’ll be able to increase VRAM on Windows 11:


VRAM (also known as video random access memory) is a buffer that stores data temporarily so that it may be retrieved rapidly by a graphics processor unit. By increasing the capacity of your VRAM, the frames will be rendered faster and you’ll notice less screen flickering and FPS-related issues while rendering graphics, gaming, and watching 4k videos.

Video RAM is an important component of the GPU since it stores all of the data that the GPU will process and produce in form of images and videos.


1 GB – 3 GB VRAM: Required to run basic applications such as MS Office Apps, and games that don’t rely on memory extensive graphics, and hardware resources.

4 GB – 8 GB VRAM: For moderate video editing and 3D modeling that doesn’t demand a lot of VFX effects for rendering, as well as games that require a reasonable amount of resources to create mid-quality visuals. You should expect to utilize 1080p with some minor latency due to rendering difficulties. Most of the time, it’s adequate to render mid-level graphics utilizing Photoshop, Illustrator, and other similar programs.

More than 8GB VRAM: Ideal for video editing and 3D modeling, rendering complex textures and graphics as well as other memory-intensive applications and apps.


Step #1: Press the “Windows key + I” key combination to open Windows Run, type and open: dxdiag (DirectX Diagnostic Tool).

Step 1: Restart your computer, press the F2, F8, or F12 key to enter into the BIOS. If these keys don’t work, search for the steps to enter into BIOS on your motherboard.

Step 2: In the BIOS menu, locate options such as Graphics Settings, Memory Settings, or Video RAM Settings, usually found in the Advanced section.

Step 3: Select the “Pre-Allocated VRAM” option and choose the amount of VRAM that you want to allocate.


As we’ve discussed, VRAM (often known as the frame buffer) is a buffer between the computer CPU and the display. When images/videos are to be shown, they are first read as data from some type of main (non-video) RAM by the processor and then written to VRAM.

The CPU and GPU work synchronously to render frames to the display. The less the latency, the better the frames are processed and delivered to the display. If either the CPU or the GPU is underpowered, you’ll face delays and rendering difficulties. So upgrading the dedicated GPU and CPU will improve the graphics processing.

Step 2: Navigate to the following file path:
Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Intel, right-click the Intel folder on the left pane and add a new key named GMM.

Next Steps

We’ve covered how to increase VRAM in Windows 11. You can use any of the listed methods above to increase Video RAM in both NVIDIA and AMD GPUs.

Overall, we can conclude that it totally depends on your computer’s hardware (especially, CPU and GPU) capabilities on how much VRAM can you increase. Allocating more or less VRAM will again cause issues such as fragmentation,
