7970 ASIC Quality - Page 7

post #61 of 87
1250/1650 1.200 but can run 1.187 to do it also.
1.200 just to be safe under load and high Ambient here.
444

Brand new Sapphire 7970 OC 67.7% ASIC maxed out safe/stable OC of 1150/1775 or so, at 1.181v. Starts to artifact when it hits 65c regardless of voltages or clocks. Anyone w/ a card underwater w/ a higher ASIC wanna trade? I hear the lower ASIC cards can actually clock better when put under water.

84.3% ASIC Here, At 1250/1650@1.200v and would seem to me that blocking any card is going to improve the
Clock or ASIC because it lowers the heat allowing you to run a higher Core and Mem number.

Don't think the ASIC number at default would make any difference.

Don't bet any great amount of money on it. I just put a waterblock on mine that was at 1200/1600 with an 84.7% ASIC. No change. I brought the memory up to 1800 but I could've done that on air.

Was worth it for the 30c drop in temperatures though. I don't have to worry about burning anything up anytime soon.

Nobody knows. Looking at the ASIC and trying to predict the overclocking potential of a card is like looking at the tire of a car and trying to predict it's top speed. All it's really useful for is judging whether you'll be able to up your clocks by switching from air to water cooling..

Just got my 7970 Lightning today biggrin.gif

ASIC is 82.3. I think it's a bit high for a Lightning as other Lightning owners have reported ASIC of mid 60s.

What do you guys think? I'll start to crank the OC a bit later in the week. smile.gif

Right now, I just want to game and see what this puppy does at stock!!!

So got round to clocking mine so ASIC is 87.4% and currently gaming stable at 1250/1375 1.187 volts and going lower biggrin.gif

Is this good or just average?

That is the best I've ever seen so yeah, don't worry about. People are doing well do get 75 ASIC.

Wooow my dreaming card biggrin.gif Yup I hope it does overclockwell with ASIC 82.3% thumb.gif
I used to had powercolor 7970v2 dualfan with ASIC 62% and only max at 1200MHz mad.gif but at stock vgpu it could do 1140/1700 smile.gif
