Increase VRAM Using the BIOS/UEFI
Some Windows PCs and laptops will let you assign more system memory to the onboard GPU in the BIOS/UEFI. To do so, access the BIOS or UEFI as explained in this guide. Each BIOS and UEFI is a little different, depending on the manufacturer and BIOS/UEFI version, so you may need to refer to the manual to find out any specifics for access keys and layout. When in the BIOS/UEFI, search for menus labeled Advanced Features or Advanced Chipset Features. If you can find them, you want to look within them for Graphics Settings, Video Settings, and similar. Ultimately you’re trying to find an option that allows you to change VGA Share Memory Size or VRAM Size. If these options exist within your system’s particular BIOS/UEFI, then you’ll be able to change between 128MB, 256MB, 512MB, or maybe even 1024MB. If you have 2GB of system memory, select 256GB; if you have 4GB, select 512MB, and if you have 8GB, select 1024MB.
Increase VRAM Using the Registry
Another method to increase VRAM in your PC is through the system registry. This is a little more complicated and if you don’t know what you’re doing you can damage your Windows installation, so be careful and read up on how to access and use the Windows registry before trying it. Consider making a Windows system restore point too.
Check How Much VRAM You Have
Dedicated Video RAM, or VRAM, the colloquial term for the amount of memory (RAM) your system’s graphics processing unit (GPU) has access to, can be a major factor in your Windows PC’s gaming and 3D rendering performance. Without enough of it, assets have to be pulled from the far slower system storage.
If you’re using an AMD APU, change the last menu option in that chain to AMD.
Before you attempt to increase VRAM in your Windows PC, you need to know how much you have already.
If you’re not sure whether you’re using a dedicated graphics card or an onboard GPU solution, then this screen will tell you, too. If your Chip Type is listed as an AMD Radeon Graphics Processor or an Nvidia GTX device, you are using a dedicated graphics card. If it says Intel HD Graphics or AMD Accelerated Processing Unit, then you’re using onboard graphics and may be able to increase your VRAM.
