Anybody want any other kind of #'s... ? besides power consumption

Very nice. Thumbs up :thumbsup:

Very nice, my reference 7970s seem to be topping out at around 1250mhz. I was going to hold out for lightnings + water blocks, but I got too good of a deal on reference 7970s with waterblocks to pass up. I'll go crazy next gen

What voltage is that at?

 

[Tempered81]

Yeah screenshots of gpu-z sensors and Afterburner log while loading the video card. HWinfo64 screenshot too, it'll show your vrm current and amperage load with temps. Would like to see the voltages and temperatures of the card to get an idea of how it's running and if there's any more clock potential inside.

With aux, pll, and mem voltage and 100% fan that memory should be ~1900-2000 instead of 1600. 1300 is already pretty nice for the core.

I stopped at 1300/1600 because those are the limits I'm seeing in afterburner.

Is the picture squished vertically?

 

[lavaheadache]

no, camera is off center and the case is tilted againt the desk.


edit** I just thought of something. I have never tried the "ln2" bios. I wonder if that is why I have the 1300/1600 limit and no pll and mem voltage adjustments? I'll try them out later hen the wife and kid go to bed. Till then I'm stuck on my lappy in the living room ()

 

[spinejam]

Nice! How's the temps?

Nice, I just got mine benched too after some tweaking and aiming for 10K score:

I noticed you have a different driver too, is that the Beta 12.7? If yes, how is it so far? And is it official release or the leaked? I'm running 12.6 June 4 release, so far no problems.

 

[lavaheadache]

yeah, I'm running the 12.7 driver. It's an awesome driver. Skyrim seems to be completely sorted out, lol... Only took 8 months =)

The only game I'm not happy about is Arkham City. Honestly, it's because I am extremely picky though. I don't like how there are lots of little hiccups as I fly around the city. Almost "feels" like multi gpu microstutter. My 680 did it too so I'm not overly concerned that it's my card or AMD's drivers. I really only notice it while gaming on my 60 hz 30" screen and not 120hz 1080. I guess I could narrow down the culprit if I wanted to. It could be that the demand of 2560x1600 is rearing it's head or that 120hz is able to hide the hiccups.

Glad I don't play Skyrim. Did the notes for the 12.7 drivers mention Diablo 3 and allowing forced AA through the CCC? The way I do it now seems shady (it works) and I'd rather want something legit versus forcing overrides through a third party user app haha.

I wonder why Afterburner is capping you at 1600 for mem? It goes all the way up to 2475 with my reference Sapphire 7970.

Very nice clocks OP. How is your fan profile with that oc?
