Two questions about a GTX 470

post #1 of 4
Thread Starter 
Question Two: My card is FurMark stable at 870/1740/1700 but is not OCCT at these clocks. i cannot see the artifacts in OCCT, but on the artifact counter it gives me about 50 for a 5-min run. Would you call this stable?

Question One: Is 870/1740/1700 a good or expectational overclock at 1.087V?

EDIT: My temp are 85C at 70% fan

Stable is a relative term. I don't call something stable unless it can run all day every day at max load without error (I fold a lot). You could back off your overclock 20 or so MHz and you would probably fix your artifacting, or you could bump your core voltage. 870 seems like a pretty good OC though, If I recall I was only ever able to run Heaven benchmark at around 850ish (give or take). That said though my card will only fold at around 740.

I consider it stable if I can pass 20 minutes of OCCT, 8 shaders (or whatever) with Error Checking on, and have FIVE or less errors. It's never steered me wrong yet. I'm 24/7 folding stable with the clocks in my sig, and it passed 20 minutes of OCCT with only 3 errors.

When I started getting more errors (at 810 core), it fails to run Folding@home.

870 is awesome OC on air at 1.087 on a 470. I need 1.1V to hit 850 stable.

AFA my cards technically being 'stable', personally I could give a crap ... as long as I don't crash while playing my games, it's stable enough for me
