Need GPU benchmark for 24h 6950 testing

post #1 of 11
Thread Starter 
I have got some worthwhile stable clocks on my 6950 and was wondering if there's anything out there that will assure me of some stability (similar to Prime's 24h blend test for CPUs). I've used GPUTool to find out my clocks up to this point and was wondering what I could use to do a longer test? Thanks.

Not trying to fry, just making sure it's stable.

you don't need to run it for 24 hours. a gpu is not like a cpu lol. run msi kombustor (not furmark) run it for 30 minutes or so. if you see no artifacts and it didn't crash then most likely you are stable. play your games for about an hour or more. if it works perfectly then it's stable.

fyi: although a stress test that I can think off that you can run for 24 hours is gpu folding although it's really not an indication if you're gpu overclock is stable. I have specific clocks on my 480 SLI which is stable for folding 24/7 but not stable for gaming so forget about it tongue.gif

Furmark/Kombustors are good at producing heat and unnecessarily stressing your card, but they do not test for stable overclocks like a game does.

If you run it 24hrs on furmark or something stupid, you will fry the card.

Here come the flames....

Run BF3 for a while. Trust me, I'm serious. It has exposed every unsuccessful overclock I have tried. If you can get an hour out of it without crashing, then you are stable for anything else IMO. I ran Furmark when I first got my TFIII 6950 and it shot my temps up to 80 degrees before I stopped it and swore off programs of the kind. I agree with the post above regarding Kombustor (in AB) That's what I run for about 25-30 mins. Has't failed me yet. Yet. YMMV

Good luck, you've got a great card. Now go unlock that beast. http://www.overclock.net/amd-ati/1070678-unlock-oc-6950-tf3-twin-frozr.html

Kombustor is just a newer/similar version of Furmark, is it not?

I found Kombustor a complete waste of time. I could clock the card, run Kombustor np for half hour, producing some god awful heat. Then fire up BC2 and it would crash in 5 minutes. Far easier to test and nowhere near the temps on the card needed to find its weakness.
