Massively pleased with it.

One thing I can say is that the cooler is silent even under load.

TBH I still need to bench it properly and stuff but oblivion has has me by the danglies

That 1.4v mod looks really simple, and the guy can reach 644 on the core with a stock cooler! The 1.5 mod seems pretty easy too, but i dont really want to be soldering a new resistor to my card.

 

[Bookime Wood]

Yep the 1.4v mod looks a doddle

 

[pinkacidbootson]

One question, where do i get conductive ink? I definataly want to try this mod!

EDIT: It seems conductive ink can also be used for a 1.55v mod! Its just too easy

Hi guys, i'll be doing the 1.55v mod tomorrow on my XFX 7900GT w/ Maze 4 so watch this space

I just overclocked using ati tool, it found the max memory to be 1800mhz ! I havnt tested it with any games yet, but it was artifact free for ages in ati tool. Just hope it works in games

whats score now ?

 

[pinkacidbootson]

9700 3dmark05 points. Which is good, but ive heard of people getting more im at 550/1800

When you doing the volt mod Johanson?

As soon as i get some conductive ink then it'll really fly

I got 9820 with mine at 560/1640 with my spec in sig.

would have thought you would be getting more maybe breaking the 10k.

what drivers are you using?

 

[loltim]

Just wondering whether to try the 1.4v mod first, 0.25v is a very big increase.

 

[pinkacidbootson]

Im using the latest 84.21, when i first got em they gave my 7800gt a nice boost, maybe my 3700+ is letting me down

Just wondering whether to try the 1.4v mod first, 0.25v is a very big increase.

Thats what im going to do, as it looks like going from 1.4 to 1.55 is as easy as a couple more lines of conductive ink

Asus 7800GTX

Autodetects 680/870. If I put the core to 700, i can game for a few hours, then i get a freeze up, no sparklies or anything, does anyone else get this? Im not sure if the rest of my rig is totally stable to rule out what is the problem.
