ATI 4850/4870 voltmod thread

[rym]

bothcrads have acelero cooler 1.rv2
I have both cards running 775/1150 one at 1.26v and other 1.29v.
No volt mod on ram for both cards.
The one with 1.26 /pencilmod ran an hour under ut3 bot match great. I enter god mode and playdead and watch the screen with 31 bots. Ut3 is a great tester.
The other with 1.29v var/resister full 100k. needs to be tested better.. I played ut3 on the net for about 15 20 mins ..
want to see if it will run at these speeds @ 1.26v
Ram sinks get very very hot.
I want to find the sweet spot volt/oc/heat to throw on non variable resisiters hardmodded for duration of next year or so.
I think these gpu's like voltage .

Thanks demoneyes for your help here.
