Before starting, you should know that you cannot increase your PC’s dedicated video memory unless you upgrade your GPU. The dedicated video memory is built into the GPU itself and cannot use more than the specified amount. However, once the system runs out of dedicated memory, it uses the system memory, called the shared video memory.
When a PC uses shared video memory, it uses the allocated amount of memory from RAM or the Virtual Memory to complete its task. However, the physical memory cannot perform the job as efficiently as the VRAM. Thus, the graphical processing task will take a considerable amount of time.
How to Increase VRAM?
If you want to increase your total video memory, you need to increase the shared video memory. Follow the following methods mentioned below to increase your total VRAM.
Using the BIOS, you may enable/disable any piece of hardware connected to a computer. Not only this, you can adjust the amount of RAM that the PC can use as video memory. However, this will increase the shared video memory only and not the dedicated video memory.
Follow the steps mentioned below to increase the shared system memory.
Change Registry Value
Before starting, changing the registry value will only change the number that the OS displays as the dedicated memory or the VRAM. This will not change the actual VRAM of the PC.
You may be thinking if it does not increase the VRAM, why is this method necessary? Well, changing the registry value tricks the OS into thinking that the PC has a GPU with the set amount of VRAM. This can be especially useful when your computer does not run games due to low video memory.
Note that the computer’s VRAM is not the VRAM you set by changing the registry value.
Any wrong changes to the registry can cause the entire system to malfunction. Therefore, before making any changes to the registry, ensure youbackup the registry.
Here are the steps to change VRAM from the registry.
Note:changing the registry value to change the dedicated video memory may or may not work on all PCs.
Switch to a Dedicated Graphics Card
Finally, if you want to increase the VRAM or the dedicated RAM permanently, we recommend that you upgrade your graphics card. A computer with an integrated graphics card will not perform as efficiently as one with a dedicated graphics card.
