Do you want to know how your VRAM works? In this post, I will show how to increase dedicated video RAM in Windows 10, 8 and 7.
You can increase the VRAM available on your PC, but if your hardware isn’t supported, you can fake that amount in Windows as well.
The first thing I’d like to tell you is that if you want a real performance boost, you most likely need a dedicated chart.
These methods will give you some improvement or allow you to run games and programs that you couldn’t due to lack of RAM, but the difference in performance will be small.

What is Dedicated Video RAM (VRAM)?
VRAM is a type of memory specially designed to perform a specific type of tasks in graphic applications and video games. We can say that VRAM is to the GPU what RAM is to the CPU .
VRAM has a peculiarity: the high frequencies at which it works. To illustrate this, nothing better than a comparison. While DDR4 memory runs on a 128-bit data bus and is clocked at 3000 MHz, GDDR5X memory used in graphics cards like the GTX 1080 has a 256-bit bus and is clocked at 11 GHz.
In addition to higher speed and bandwidth, this type of memory has lower consumption, the core of its operation, since it allows increasing the voltage while maintaining the temperature at adequate levels, obtaining excellent performance and frequency.
How much dedicated video RAM does my PC have?
To find out how much dedicated video RAM you have allowed, you need to follow these steps:
- Right-click anywhere on your desktop and select the Display Settings option .
- Scroll down and in the Multiple Displays section, click on the Advanced Display Settings option
- Now click on the option: Display adapter properties for Display #
- In the window that opens, you can see the amount of Dedicated Video Memory.
Method n. # 1: How to Increase Dedicated Video RAM (VRAM)
If you want to increase the dedicated video RAM memory, the essential requirement is that the hardware is compatible. This means that both the processor must have integrated graphics (APU) and the chipset and the board must support these modifications.
This method will work on both laptops and desktops to do so, follow these simple steps:
- Restart your computer and enter BIOS setup. Generally, you will need to press special keyboard keys during startup according to your motherboard manufacturer, for example ESC , F2 , F8 , or F12 .
- Once in the BIOS / UEFI, it will depend on the version and the manufacturer, but it is not difficult to find the settings for each brand.
- You should look for an advanced menu, advanced chipset features, or the like. There you will see several options or submenus appear, some related to graphics settings, video settings or VGA memory.
- If you implement it, it should appear to you to select from various amounts of MB. Typically, default is 128 MB or 64 MB depending on your hardware, but is there to put the maximum value that allows the amount of RAM.
Remember that the RAM that you dedicate to graphics will not be available to the system, so if you have little you may want to adjust this parameter. Once modified, save the changes, the PC will reboot and Windows will detect the new amount of VRAM.
As easy as that, you will learn how to increase the dedicated video RAM on your computer or laptop.
Method n. # 2: Fake VRAM on Windows
Now if you tried the process above and there was no even remotely similar menu, you can do two things.
Take some pictures of your BIOS and put them in a comment, or in case you want to increase it because some program or game is not running because it is low on VRAM, you can change the value manually (fake it).
Note: Changing this value will have no impact on graphics performance, you are simply telling Windows that the available graphics memory is X. This is because other programs ask the operating system how much memory is available, and they will believe that the amount you set exists.
To increase the dedicated video RAM, you will need to use Registry Editor. I always advise you to do it at your own risk, because if you touch something and make adverse changes, you can damage your system.
To modify the amount of dedicated video RAM, follow these simple steps:
- Press the keyboard shortcut: Winkey + R
- Copy and paste this command: regeditand press Enter
- Once in Registry Editor, navigate to the following path: HKEY_LOCAL_MACHINE Intel Software
- Right click on the Intel folder and create a new key called Uppercase GMM .
- When it appears, right-click GMM and it should now create a 32-bit DWORD value . Save it with the name: and select the Decimal option .DedicatedSegmentSize
- The number you enter will be the “megabytes” of dedicated video RAM or VRAM that you want to appear in the operating system.
- After this, you just have to reboot for the changes to take effect and you can see the new size of your graphic in the hardware properties.
