Hi Guys, just want a little help from U with the Vmod on 7970oc rev2.1 First of all, whats the best spot for ground? A radiator, screwhole, one of the pins on 8pin-6pin socket? What value has to be on the trimpot. Some website says 40-50KOhms, some mention 100KOhms? I just want to have max 1.3V on the GPU. Which one i should put? Do i really need the OCP mod if i want to push the card to 1.3V? Here`s a pic of the ADP4100 VR on my card http://img692.imageshack.us/img692/5466/r4h6.jpg and the last thing. if i want to read the actual voltage the red wire from MM has to go to on of the capacitors marked by der8auer and the black to the ground? Thanks
