In my Bios I can set it from 1.5v to 1.8v and it was orignally set at 1.5 so I set it to 1.7v, can anyone explain what it does exactly? I've been told before it makes the card run smoother because it gets more power but I'm not so sure about that.
Basically fries your video card. It pumps more power into the AGP slot, but the video card has it's own BIOS and will use only the power it's told to use.
Put it back to default because it won't help you at all.
