How to Increase Dedicated VRAM in Windows 10 [2021]


In this article, We will share how to increase Dedicated  VRAM in Windows 10″. Maybe you have experienced an error related to a special RAM video on your Windows PC?

Trying to run a graphics-intensive processing program: a new video editor and video games?

Now here you might need more Vidio RAM (VRAM) to run a program or play a game to be more stable.

How to Increase Dedicated VRAM in Windows 10

Before you upgrade VRAM, it’s best if you need to know about VRAM.

What is Dedicated VRAM

Graphics-intensive applications and programs use large system memory space to render graphic data with high quality, color, clarity, and definition on the screen.

In these cases, the system may suffer from a shortage of RAM and have difficulty storing high-intensity graphics programs, as the graphics card shares the system memory.

Otherwise, to store the high-quality display on your system monitor, you will need a special type of memory called Video RAM (VRAM).

Video RAM is dedicated to a special purpose – to process high-intensity video faster than system RAM.

Graphics cards or the GPU use the Video RAM (VRAM) built on top of it to store images and video data.

VRAM is also called virtual RAM and is used as GPU memory to easily process graphics applications, games, complex textures, and 3D graphics.

However, some apps like the latest games and videos may require you to play videos with 1080p or 4k resolution and need a lot of VRAM.

In addition, VRAM processes more pixels for higher resolution images for better viewing.

That being said, modern games require a higher level of detail and exact system requirements to run on the system monitor, and without sufficient VRAM it will lead to severe GPU overhead.

History of VRAM

VRAM was first discovered by F. Dill, D. Ling, and R. Matick in IBM research in 1980 and then patented in 1985.

Prior to the creation of VRAM, dual-ported memory technology was quite expensive and of limited quality.

Until finally in 1986, for the first time, IBM introduced VRAM commercially to its PC / RT system which later became the standard for graphic displays.

What Are The Different Types Of VRAM?

In general, the VRAM has the same function. But if the type, there are several types of VRAM that you should know include:

  1. Synchronous Graphics RAM (SGRAM): This VRAM is the clock speed of memory that is synchronized with the speed of the laptop CPU.
  2. Multibank Dynamic RAM (MDRAM): This VRAM has a working system by dividing the amount of data into several parts.
  3. Rambus Dynamic RAM (RDRAM): This memory was developed by Rambus. Namely, a technology company is known for its quality. RDRAM is a type of memory that has a bus to speed up performance between VRAM and Framebuffer.
  4. Windows RAM: This RAM has notoriously high performance because this RAM has a relatively faster clock speed.

RAM memory types are also differentiated based on the capacity at the clock speed and bandwidth capacity.

In essence, the higher the RAM capacity, the better and faster the VGA performance will be, the following is RAM memory based on clock speed and bandwidth capacity :

DDR2: Clock Speed on this RAM can reach 800 Mhz or more

DDR3: The clock speed of this RAM can reach 1800 Mhz or more

GDDR5: Clock Speed ​​on RAM can reach 6000 Mhz or more

As time goes by, for those of you who frequently update hardware, now there is a type of GDDR6 memory, which has a higher development clock speed than before.

In addition to the different clock speeds, video cards usually also have different power efficiencies in performance. The cool term is watt to performance.

Why Do You Need VRAM?

If you have insufficient VRAM, you will not be able to run modern games. In such a case, you will need a graphics card that has sufficient VRAM.

To easily load complex textures with high-resolution images, you may need to increase the amount of dedicated video RAM on your graphics card.

How to Increase Dedicated VRAM in Windows 10

The best way to increase VRAM and the most effective so far, which works 100% of the time, is to get a new graphics card with a larger VRAM.

If you have an older generation video card, it is ideal to get one of the newer cards.

Note that you will still need to verify that the new card is compatible with your computer’s current hardware configuration.

You will also have to check for bottleneck problems between the processor and the new card, which can be done with this bottleneck calculator.

Not everyone can buy a new graphics card, and if you belong to that category, there are still some ways to increase the dedicated VRAM in Windows 10.

Before trying the methods to how to increase VRAM, you must first check how much dedicated video memory your graphics card has in Windows 10. So you must know How to Check How Much VRAM Have In Your PC?

1. Increase the Dedicated VRAM on Your Graphics Card from BIOS

This is the recommended method for reallocating memory from VRAM allocation. However, this does not work for all motherboards, and you may not be able to reallocate your PC memory on your own.

Still, you can try changing your BIOS settings and see if you have sufficient privileges to change the amount of dedicated video RAM on your PC.

Restart your PC and press the BIOS key – F2, F5, F8, or Del repeatedly during boot.

In the BIOS menu, go to Advanced Features or similar options.

Now click on Video / Graphics settings or VGA Share Memory Size. If you can’t find these options, look for a category with a similar option.

Set the option that best suits your task. The default memory allocated to the GPU is typically 128MB. You can expand the pre-allocated VRAM to 256MB or 512MB.

Save the changes and reboot your system.

2. Increase the Dedicated VRAM on Your Graphics Card Using Registry Editor

Depending on the applications you run, the system automatically adjusts the amount of video RAM it requires.

Therefore, the adapted information showing the amount of VRAM used in your graphics card is not always authentic.

However, to run some applications, you will need more VRAM. In such a case, you can simply replicate the amount of VRAM to replace the amount of VRAM that your system needs to run the application.

You are not increasing the actual value, but rather increasing the amount of VRAM to a value that serves as a surrogate for the memory requirements to start the game or an application.

Follow the steps below to remap RAM as VRAM for integrated Intel graphics cards.

Open Run and type Regedit. Go to the following route:

HKEY_LOCAL_MACHINE \ Software \ Intel

Right-click on the Intel folder. Choose New and click Password. Name the key as GMM.

Increase the Dedicated VRAM on Your Graphics Card Using Registry Editor

Select the new GMM folder in the left sidebar.

Right-click on the right side of the window and click New from the drop-down menu.

Increase the Dedicated VRAM on Your Graphics Card Using Registry Editor

Choose Dword (32-bit) and name it DedicatedSegmentSize.

Double-click DedicatedSegmentSize and click the radio button with the Decimal option to set the base to Decimal.

Enter the number of megabytes of RAM that you want to allocate as VRAM in the value data. Be sure to write a number within the range of 0 to 512.

Increase the Dedicated VRAM on Your Graphics Card Using Registry Editor

Save to apply the changes and Reboot the system.

FAQ’s On Increase Dedicated VRAM

Q 1. Is it Impossible to Increase the Capacity of Dedicated VRAM?

Ans:- This is not impossible as long as the computer really supports it. Because there are several ways that I shared above and users can try both methods.

The Final Word

This article is about how to add a computer VRAM that you can try yourself. Most people want to increase VRAM capacity, but maybe there are still many who are confused about how to increase it. So hopefully this article can answer the problems you are experiencing.

Actually, the increase or addition of VRAM that is meant to be added here is shared. Not dedicated memory.
