Ditto for me. Whether I crank the clocks speeds up or leave them at default, the benchmark scores seem to stay the same

I dunno if i could raise the clocks much more.

My experience in the past with the 7900GTX was horrible.
They need to be conservative with factory oc'ed cards. They have no way of knowing what kind of cooling customers will have, I'd be surprised if the oc'ed model didn't get close to 2600. They are supposedly tested to higher standards, so in theory, they would oc past the average. I think that more applies to the core though, as the memory is all .8ns if im not mistaken.

It also should be pointed out that the lifetime of the card is going to drop drastically with these overclocks... card might burn out in 3-6 months.

I should also point out I've overclocked everything I've ever put my hands on and I've yet to "burn out" a piece of hardware.

Lucky you. I've burned out 3 cards. I've stopped overclocking and started just buying factory overclocked cards, at least then I can send them back.

I am on 11989 for the GPU now in Vantage. My previous results were on P35 using DDR2 800 ram with the 177.39 driver. This new one is 790i DDR3 1600 and the 177.41 driver. My old best GPU score was 11704, now it's 11989 with the same GPU clock. Difference is driver and platform.

http://img156.imageshack.us/img156/8...age790ixw6.jpg

Total score 14605, validate-

Card was @ 742|2600 1547 unlinked.

Looks like I have one of my clock speeds too high. I started running around in Crysis for 5 minutes and the colors went all funky So I guess I'll have to go back through each clock one by one to see which one it is.

I'd say your shader clock is too high. What fan speed are you using? The core clock isn't too high but I found going past 700 was pointless.

It actually turned out to be the memory clock. I dropped it down a tad from 2600 to 2538 and all is well again I just have the fan on auto but I've never seen the temp go above mid 80's.

Its probably something else that is overheating and not the gpu temp i got same problem and if i set fan to 100 percent it was without artifacts, so in my situation, temperature was problem.

I'm pretty happy with my GTX 280 OCs, I can't seem to raise the shader anymore though "Oh well"
