Bahah, I have had that page bookmarked for days now.

Tried everything with it, thanks to it I managed to change the bandwidth to 4x.
There are no such controls in my BIOS.

The only thing I can do is change the 4x/8x bandwidth(which doesn't really do anything) or choose aperture size, nothing that lets me adjust voltage or anything. Is there any software that can do this safely? One of the Steam support articles suggests to set the voltage to 1.6v.
Would you suggest swapping the power connectors of my card for that of another device hooked up to my PSU? There are only 2 HD's and 1 DVD-rw in my PC, and my card gets the 4th power connector. They all get the same amount of amperages right, so it shouldn't matter?
I ran that HDR test thingy it ran fine, solid 24fps but it felt smoother.
