7800GS Volt Mod?

post #1 of 10
Thread Starter 
I heard that there is a volt mod I can do to hit insane clock speeds. ATI tool says I have a G70 core. Is it really hard to do? Can somebody who has done it before help me out
Thanks

I know that it involves soldering 95% of the time....so for me, yes it's hard

I think it's probably well worth it tho, however you are taking a much bigger risk increasing the voltage to your card than you are by just overclocking it with software.

I voltmodded my 7800gs. It has a g71 core and the clock speeds are now 673/800. It happens to be really easy. And whatever you do, DO NOT follow that vr-zone guide. Also, you don't have a g70 core, it's g71, check with rivatuner.

http://forums.guru3d.com/showthread.php?t=200420 The first picture will get you to 1.50. Just strip a wire, and take a small thread of wire out and thread it through the hole under the screw and that other hole. Send me a pm if you want to do a vmod on the memory.

To check whether you have g71 or g70 open rivatuner and look right under the first drop-down bar.

I did the volt mod and I still get artifacts after 520, I used a piece of stiff copper coax cable wire, wrapped it around the screw and made it make contact. I heard people hit 700 with this mod, did I do it wrong or what?
