I wonder if later supplies of these cards will be able to overclock as well as the initial batch? I've got another one coming in, and am kind of worried the initial batches were the better ones. I've seen signs of people getting cards (as well as reviewers) now that will do only 1,150mhz @ 2.4volts which is horrible compared to the initial review units, and a few of the cards people got on launch. A good ~100mhz shy is a big difference in silicon quality on these GPUs with all other conditions being equal.

I just got my gigabyte yesterday. 74% asic (means nothing) went straight to 1260/1700 on water. I'm gonna try to tweak more when I get home, but I think we are hitting a locked vcore wall.

I did google Denim-187 sapphire 7970's review came up. Which led me to purchase them. I've been pm'ing him and he's been answering all my questions about them he's been very helpful. Hell I made an account to pm him so what he posts is quite useful.

Sure, you go ahead and shoot 2.4V into that chip for 1150 MHz. I can manage that at 1.112V. Good luck! thumb.gif

I lover this forum, the best ever smile.gif

Oh, I want to grouphug.gif you all smile.gif

If I buy another 7970, I hope it overclocks as good as the one I have now, hence they overclock about the same.

If I have a 7970, and buy a 7990, would that result in trifire, as if I had 3x 7970?

Yes a single 7970 with a dual 7990 would equal tri-fire (3x 7970) performance. thumb.gif

Assuming the 7990 has the same core clock as the 7970. If not, just overclock it to match thumb.gif
