ATI 4850/4870 voltmod thread

[Vatos_locos]

Great job finding the pin-out diagram Looks like my original "shot in the dark" mod was a bit off the mark...it's working much better now

I've updated my orignal post with your new info and all due credit

BTW, what clocks are you running with 1.4v? I can only get up to 880mhz Furmark stable.

thanks m8

same shi(f)t here i can get 880Mhz with 1.5Vgpu and then i get full of artifacts
my card seems that is not a good overclocker at all
are you using a different bios or the original one ?
