How to Increase VRAM or Dedicated Video Memory?

VRAM is responsible for the smooth running of all the graphic oriented programs just like RAM is for the smooth running of any application or Operating System on your PC. Increasing VRAM can highly improve the performance of graphic intensive tasks like Gaming, Video Editing, Rendering 4K Graphics, etc.

Before we move on to “How to Increase VRAM?” let’s first understand what VRAM really is and how it really helps?

What is VRAM or Dedicated Video RAM?

Like RAM momentarily stores the temporary data relating to the program to make it quickly accessible when required by the CPU, VRAM stores the data regarding the GRAPHICAL part of the program to render high-quality images quickly which would otherwise have taken much more time. More VRAM means higher FPS while Gaming, High-Quality graphics in everything, etc.

While RAM relates to CPU, VRAM relates to GPU in totally different ways. High-end PCs have Dedicated Graphics Cards that contain VRAM or Dedicated Video Memory to help in high-end video output.

In PCs where there is no dedicated GPU, there is a part of memory/RAM which is shared for both normal programs and graphical needs.

How to find out the amount Dedicated Video RAM your PC has?

Before we move forward to learn ‘How to Increase VRAM’, let us first determine how much Dedicated VRAM you currently have. To do so, follow the steps given below:

Step 1: Go to Start Menu > Settings > System.

Step 2: Scroll down in the Display menu to find Advanced Display Settings.

Step 3: Clicking on Display Adapter Properties for Display 1 will open a Dialogue box with the information about Dedicated VRAM, Shared System Memory, and Total Available Graphics Memory.


  • Dedicated VRAM is the space that will only be used for the Graphical Purposes.
  • Shared System Memory is the RAM that is used for both Graphical and Non-Graphical Purposes according to need.
  • Total Available Graphics Memory is the sum total of both Dedicated VRAM and Shared System memory.

What can you do if the above-mentioned methods don’t work?

As we mentioned earlier, VRAM is an absolute requirement if you are trying to run some graphics intensive task on your PC like editing High-Resolution Videos, Using 3D Graphical Software, Gaming, etc.

Increasing VRAM through BIOS and Registry Editor can surely help sometimes. Especially in the case where everything already seems to be running fine and you just need an extra bit of Graphical performance from your PC for the seamless performance.

However, these methods may not work in other cases where the program doesn’t even run without allocating VRAM. In those cases, upgrading to a Dedicated GPU or Graphics Card is the ultimate solution. A Dedicated Graphics Card provides the real horse power needed to run some really graphically demanding programs and software.

Graphic Cards vary in specs, horsepower, and price. One graphic card can’t be the ultimate solution for all the different kinds of user. If you need help in choosing the right GPU for you, you may want to consider reading this article – Best Graphics Cards February 2021.
