Not seeing any artifacts in Furmark, but Evga's OC Scanner see's some

post #1 of 7
Thread Starter 
I'm overclocking my card right now, and I usualy use oc scanner. I have noticed though, that my gpu usage is only 93% with oc scanner, while in furmark it is 99%. These are my settings: 841 core 1925 memory 1.138v. Oc scanner doesn't show any artifacts with those settings, so I tried to bump up the core clock. I bumped it up to 850, but I was getting about 89 artifacts every 30 minutes. I then tried furmark. Furmark doesn't have an artifact scanner, but it stresses the gpu more. I was wondering, if I don't see any artifacting in furmark or kombustor, is it okay to say it's stable? I also run I few benchmarks after I overclock. Will I be safe, or do I have to stick with what oc scanner tells me? Thanks!

If OC scanner is showing artifacts then it is not stable. I'd keep it at the 841. However, if you are just looking to bench and it's not effecting your score then you'd be alright running it for a brief period of time to bench.

Also the obvious lock ups/ drive crashes.

Some OC software will find instability when others do not, just the way it works. I've had over clocks pass all the OC software I could throw at it but then crash in game.

Furmark really isn't much of a stability test, it'll tell you how hot the card can get, but even if a card is stable in furmark without artifacts I have found it may not last 10 seconds before crashing in a game or folding.

It will pass games just fine. I ran the crysis benchmark with 10 passes, and then did the just cause 2 bench 3 times, and the dirt 2 once. When oc scanner does though, show artifacts, I can't see them at all.
