I have a 5850 that is clocked to 1000/1300 running with a full water block to keep it cool...The VRM's get toasty hot(On Air) and will limit your overclock so don't get too crazy smile.gif

When I flashed my bios I also use the modified Asus bios. I used Radeo Bios Editor to modify the 2d clocks, 3d clocks, sliders, and the voltage. Kinda set it and forget it way of doing it.

RBE can be found here http://www.techpowerup.com/rbe/

The exact things to change I'm unsure of now as it was a couple of years ago that I did it. Looking at the images on the page I think it's the voltages listed on the clock settings tab. Guess you'd have to open up your bios (tho one you flashed) with RBE and take a look and see if it's about what you see with other apps and take it from there.

Ok I took a look as I still have RBE and the bios file I flashed saved on my storage drive. I viewed the original copy of the Asus bios and the one I flashed also. I came to the following conclusion.

To change the core voltage one needs to click on the clock settings tab > GPU registers > 0x018 field looks to be what sets my voltage(3d)....You'd need to alter it and then save it, flash bios and see if it also will control your voltage. You might wanna just baby bump it a little bit to see if it's gonna work on yours. My card is a Visiontek ref design.
