I find that FurMark isn't that good for stability--for temps, maybe but that's about it. For example, I had FurMark run stable for 30 mins on my 7970 1200 core oc, but then Deus Ex:HR crashed when I skipped a cutscene (which doesn't happen at stock speeds). So I concur that Heaven and Crysis 3 would be much better, or even some Metro 2033 runs.

thats what i actually meant, FurMark is good for finding max temps for GPU's such as IBT does the same for CPU's but both arent good for stability testing.

oh okay thanks for that. Heaven it is. I assume its a 30 minute loop? that would take a really long while if I have to test it every 25mhz increase. Can I just go to the max I believe can my card go and go down 25mhz every time it craps out?

oh and them max safe 24/7 voltage is 1.25 right? or is it 1.3?

Max safe voltage for 24/7 usage is 1300mV as long as your VRMs don't overheat (Try to keep them at 80 C or lower).
For stability try Heaven Benchmark, Battlefield 3, Crysis games & 3DMark.
For Heaven Benchmark I suggest you test the card both way, first is high framerate test and second low framerate test.
I use 1920x1080 Normal Tessellation 4xAA/ 4xAF for high fps test, and of course maxed out for the low fps test.
I know some may say this is a weird way of testing, but during the time I tested my max stable OC, my card always pass low fps runs and whenever I try anything with high framerates it doesn't take too long to crash.
When Heaven was at max my card easily passed the test for 6 hours straight, but once I put the settings to 1920x1080 Normal Tessellation 4xAA/ 4xAF It crashed within two hours period.

Is there are any decision to overclock ASUS Matrix HD7970 Platinum above 1170MHz on the core?

PS: sorry for my english, I mean decision doh.gif

You say solved in your post. Probably why no one has responsed.

Unrelated thread but the guys who ordered hunter version and got crysis 1 free does it work? When i launch it its just a black screen, the game doesn't respond. Repaired it, uninstalled and reinstalled same thing.

Forgot to ask. How do i loop heaven benchmark?

Edit:
Tried ocing already. 1100/1500 @ stock volts had no artifact while running the benchmark but when i bumped to 1200/1500 which i got artifacts and ran back to 1100/1500 it already had artifacts. Even at stock clocks.
