ATI 4850/4870 voltmod thread

What kind of increase did you guy's see when going from 2.0 to 2.1v on the memory chips ? In the past the clocks went down when increasing the voltage. Because the boards where already running the chips to the max. Lowering the voltage sometimes gave a increase.

I'm thinking about v-modding my HD4850. But i'm also thinking of buying a HD4870. Those things have 1.26v on the core stock. And run like 790 MHz (max CCC) without a problem. I dont see my HD4850 with running 800 MHz with just 1.26v.

Nothing for me

@Quake6: yes, the you can solder it to another ground if you want, this one is directly on the chip but it's not mandatory
