Volt-modding eVGA Geforce 7800GT..

post #1 of 36
Thread Starter 
I can only get 445/1070 (stock) on my card without freezing in game. I have a Zalman copper fatal1ty fan on it with artic 5 paste and a vantec dual 80 mm high speed fan below it in the pci slot. This is not a heat issue. I get 32° Idle and 46° Load.

Someone told me that my card needs to be volt-modded to overclock. Is this true?

If it is.. is this an easy process? Is it risky? Should i do this

If you got some good soldering skills with small circutry, it's pretty easy. It's very risky unless you know exactly what you're doing, and either way you can kiss your warranty good by. Should you do it? Nope, I'd find it difficult to believe your 7800GT is slow enough that you need to take a high-stakes risk on it to overclock it a little further.

yes, jealousy is a factor....BUT THATS NOT THE POINT!

those have LOTS of power, i don't see the need for more performance. like what games lag on a 7 series? come on! i can see why when you bench and see what you can get the score up to, but keeping it like that is pointless.

Why do we even need 7 seires cards when vodoo's can play doom 3? Why do we even overclock at all? Because we can and it's fun to do it! The 7800GTs aren't very good overclockers, atleast our version of the Evga 7800GT.

The on-going pursuit of performance. The GeForce 7-series cards are fast, no doubt, but they're not too fast. There's always room for improvement.

The 7800GTs characteristically aren't good overclockers because they are basically failed 7800GTXs.
