Looks like I jumped the gun a little - now some unbiased reviews have surfaced I'm going to stick with my 7970s.

So in Trixx is 1175mv and I see : 299
1157mv it looks to me...
Now what do to next? smile.gif

Nice, as I expected, 30mv drop. Push max voltage get as high a clock as you can, this will let us know what are max clock is. I suspect you will only be able to hit 1185mv inputting 125mv into Trixx so you are almost at your maximum.





A point on Heaven. Imo it is very good at stability testing, but it isn't a game so it won't put the gpu into real time pressure. You can't simulate Crysis in game or BF3, etc. So when you find a stable point in Heaven, you're not done yet. Do you have Crysis btw?

Yeah, me too a bit. So the performance boost isn't there with the gtx680. Let's just hope AMD's drivers get fixed sometime soon smile.gif

A 7970 overclocked to 1250 on the core, which is not a hard thing to do for most people with a slight voltage bump) beats the 680 around 95% of the time in benchmarks and games.

To the people taking your memory above 1375 on stock voltages: are you actually seeing performance increases? I can take mine all the way to 1600 and it's stable, but my benchmark results end up being worse than stock.

I have Crysis Warhead + Crysis Wars on steam.
Not yet installed though, wanne play one game at a time smile.gif

But as said before I am playing new batman game at the moment.

I will push the voltage to 1185mv in Trixx and start Batman today with 1100 on the core and 1500 on the memory. Lets see if that will hold up without driver error.

EDIT : isnt my drop 20mv by the way? 1175 - 1157 = 18mv or am I calculating something wrong here?

I learned yesterday this actually means it is not stable due to error correction things or something.
So if performance increases are not as high as before or even worse that means you should back down your clocks.
