ATI 4850/4870 voltmod thread

8800's@over, if you don't have a good airflow over the entire card, it will overheat...

i have a watercooled 4850 running 760/1140 on stock voltages and it overheats and shuts down if there is no fan blowing air over it, even though the core is in the low 40s

Same here, I have two Palit Dual Sonic HD4870 which shut down rather quick when there's not enough cold air blowing over the cards, eventhough the GPU temps are not so high.
They don't shut down though, but produce heavy artifacting, it's mainly the GDDR5 which start to artifact.

I'm thinking of skipping on the voltmods for these cards. I fubared my last Gainward HD4850 when i was removing the volmtod on the GPU. I gave the wire just a little too much heat en when i pulled it of the whole solderpad came with it. Tried to fixed it, but in doing so I f*cked up even more. ( so if anyone is interrested in a dead Gainward 4850 GS for spare components, just give me a PM)

Right now, I can do 860/1000 with stock voltage of 1.263v on the first card ( still testing the second)

I was wondering, does a HD4870 benefit more from a GPU overclock or a ram overclock? I know that with the HD4850's it is the other way around beacuse those card are rather bottlenecked by the GDDR3

Oh and btw, doing a RMA after one has fubared the card by bad modding is so lame.
