How to increase VRAM on Windows 8.1?

[bomziakas8]

Hi guys,
I'm confused over here.
I have a GeForce GTX 660 which on dxdiag.exe show 4 gigs of available video memory, but my pc is only using 2gb.
Because I have 12gb of ram I thought- why not increase it?
But then I went into my bios AND THERES NO WAY TO ADJUST IT!!!
Please help!

VRAM is something that's only used by the video card. It's not usable system RAM. Only way to increase it is to buy a new video card with higher RAM. With your PC having 2GB, are you actually talking about actual system RAM that's showing up under your computer properties? If so, then the only way to increase that is to buy sticks of RAM and upgrade it. Though, be sure to check that your OS is 64bit before spending money on RAM.
