Tutorial: How to softmod to ANY VGPU you want without hardmods! (1.3~1.6v or more)

Actually, as I look back through the post, it looks like the formula was listed incorrectly. I can see from the formula that is used to calculate the desired vid that it should really be:

(VID * 0.0125) + 0.45

That pointed me to 18 being the correct one, so I ran:
RivaTuner.exe /sd0 /wi1,70,18,4C /sd2 /wi1,70,18,4C

Boom! 1.4v!

yup, that was what i had a problem with at first so i just tried all the different registers until i found the one that changed idle voltage and the one that changed load. then reverse engineered it to find that the equation was wrong. yours....

Voltage = (VID * 0.0125) + 0.45

is correct. good to see that the 4870X2 is working with this method as well

Heck yeah! I ran a vantage run at 860mhz a minute ago. up 200 marks :-D Gonna try for more in a bit.
