GTX 570 Overclocking

post #1 of 8
Thread Starter 
Hey,

What are some stable core clocks? eg

850/2000 @ 1.063v, I don't know for the 570 if that is stable or not.

I have the ASUS GTX 570 DCUII btw so my card is more than capable cooling wise and my case has 3 fans (HAF 922)

Any help would be appreciated, thanks.

Hmm, I'd have to say every graphics card is different my advice is keep those settings for awhile and see if you get random driver crashes. If you do end up getting driver crashes just try upping your voltage a bit until they stop.

My only concern is that if I put the voltage up to high it will really affect the life of the card frown.gif

If my card is doing great with my current clocks, I believe your card should do better. It's a better card than what I have... Can't get it stable with lower voltage?

^ Basically what Fateful Ikkou said. You might be able to get a few more MHz on the core clock at that voltage, but yeah, every chip's different.

If you're looking for a good stability test for 570s, try Unigine Heaven for 5-10 minutes or so. If you don't get any crashes, bump up the core clock 5-10MHz, then repeat.

Good luck! cheers.gif

Edit: Oh, and many people around here consider the safe voltage to be up to 1.1v . Your particular 570 can take a little more voltage than a reference card would be able to.

So should I take a stable core clock and go down by 50Mhz then go up slowly by 5Mhz?

Oh, I just assumed that the core/memory/voltage you listed in the OP was your current OC haha.

I like to start at stock, then increase the core until it's unstable. Then, I increase the voltage by a notch, then start increasing core again. Keep going until you hit a core clock you're satisfied with or until you reach your personal max temps/voltage. It takes time, but it also gives you an idea of how well your card performs at any voltage.

Or, for a quick and dirty OC, just set the voltage to something you feel comfortable with (say 1.050v) and then increase the core clock in increments while testing stability. When it starts crashing, just back down your OC a bit.

Hope that's helpful. If anything's unclear, I'm sure other folks have some good OC tips smile.gif

My 570 DCII is 0.988v stock

Haven't really seriously tested it for stability, but 850 @ 1.05v seems pretty stable.
Playing Crysis for 2 hours and about 30mins of Heaven.

Also tried 850 @ 1.038v and it seemed ok.

800 @ 1.01v BSOD tho, playing Crysis

Haven't messed with VRAM yet.

Hope it helps
