If you can get 1150 on stock volts you got a good card. 1300 not out of the question once you overvolt in which case you got the fastest single GPU around.

I posted this before but got no replies so apologies for posting again but im really curious about it.

I'm lost with my asus directcu ii 7970. Everything is great with the card yet when I clock past 1125 I get slight artifacts but once it gets to 1200, thats when these black and white triangles start replacing textures, like chess boardish. In 3dmark it causes black and red lines, but if I change the voltage to 1.68v it becomes stable in 3dmark. Any other voltage and back to artifacting. Im stable with the.1.68v on dirt 3 for eg with v sync. But with v sync off it artifacts. I've clean installed and tried different drivers and anything else you can think of, i've most probably done it already. You reckon this could be resolved with a future bios update? Seems too coincidental that it only becomes unstable beyond the max ccc limits. Mem clock is 1700 by the way.

Just thought I'd throw it out there.. I'm using an FXAA injector for BF3 on top of my normal settings. Here's a link for the files if anyone would like to use it, it does make it look much better imo. http://www.mediafire.com/?75ioxk0plokeai4

yea the stock clock for it is already 1070, i just tried it at 1200 to see if i was super lucky and got drivers recovery. will try 1175 and see.

this is with only a few passes of 3dmarks so prolly not real stable.

I have mine at 1200/1600 with 1.225V, but I have to run 100% fan to keep temps under control. I can go higher, but it hardlocks once it hits ~75C

My 7950 arrived last night :-) should go in over the weekend. Any good guides to OCing around? I'd love to get it to clock speeds near the MSI lighnings.

well regardless i'm getting crap load of problems and instability with even 1 of them
so i got 2 of these beast ASUS HD7970-DC2T-3GD5
however tested and tried on a clean Win7 x64bit install on both Intel and AMD platform
and it crashes randomly, and it hangs on all the 3D mark benches
i have several old ATI 5900, 6800 and 6900 series, and many of even older ATI X series, all of them runs great on both rigs (intel / AMD platform)
is quite discomforting and stressful not being able to fully enjoy your $1500 purchase in game, only old games runs fine on the 7970, but most of the newer games crashes as soon as it loads into the game, regardless of Crossfire or not.
all my old cards can fully complete the 3Dmark benches without any error, yet the 7970 crashes on the spot.
I'm contemplating going for the 7800 series, since the latest Catalyst 12-3 drivers just provided official support for them.
I'll like to hear some feedback on the 7800 cards, are they as problematic as the 7970?
how about the 7950, i'll assume the 7950s faces the same issue as they are on the same trunk of the series

man you must have the worst luck....i'm running xfire with my cards using 12.3 drivers also overlclock @ 1260 core /1660 mem and i'm not experiencing any crushing running games or benchmarks
it could just be the cards it self (hardware problems) as its not reference pcb.....

can get to 1160 stock, anything over and driver recovery. 1160@1.125 max temp after 3 runs of 3dmark is 72c, i haven't seen 75c+ yet.

will go up in voltage a lil and see where i can get to.

What fan speed are you using? My 1200/1600 hits 85C at 100%, but if I go up to 1250 (haven't tested in between because I like multiples of 50 for my GPU clock tongue.gif) it hardlocks once it hits the 75ish mark. I've tried with more voltage, same result.
