GTX 570 Twin Frozr III Overclock - is it safe?

post #1 of 6

Thread Starter 
Hi overclockers,

I have just finished building my rig:

3770k @ 4.5 Ghz
z77 Sabertooth
GTX 570 Twin Frozr 3
2x4GB Corsair Dominator Platinum
Corsair H100
Corsair 850W PSU
CM HAF X Case

For my GTX 570, I have managed to overclock it to 950/2450 with voltages maxed out (+150mv core, +50mv memory, +30mv aux).

Could you please tell me if this overclock is safe with those voltages or could I get the V's lower.

Thank you

Kostacoffee

Nice build. To put it in your sig (if you want to), here's how:

Thats a pretty high clock for the 570 on air thumb.gif. Make sure your temps stay under 90c when under full load and adjust your fan profile.
But I heard stories about 570s and blown VRMs. So make sure your case is well ventilated.

I monitored my Temps and, after editing the fan profile, they don't go above 70C, maybe an occasional rise to 75C tops, but otherwise, it is all below 70.

I hope that's low enough to keep the GPU going for 2 years at least smile.gif

If the noise of the fans doesn't annoy you, then thats perfect. 75c under load for long durations is pretty good for a 950 core thumb.gif

570 VRMs are pretty well known for going pop. I'd definitely put the voltage back to stock and do your research on safe voltages - by "maximum voltage" I take it you mean 1138 in afterburner? I believe that's very high for a 570 and I'd be careful - they had 2 less phases than 580s hence the problems people have had when they are overvolted.

I'd also, in general, not overclock VRAM - it doesn't really have any noticable real world benefit, and some people have reported failed vram when overclocked. If there's no benefit to doing it that you'd notice, I wouldn't bother.

Not trying to put you off getting a decently clock, but it's worth mentioning the dangers with 570s.

After doing some research on "safe voltages" as Boris kindly recommended, I found out that my V's were a little too high. (1.138). I put the voltages down slightly and adjusted the clocks and after some stability testing, I have come to a completely super-all-game-stable overclock of 900/2250 at v1.1

And the best part... the temps don't even reach 65. SO COOL, sonofa*****. (see if any of you get that reference XD).thumb.gif

Thanks everyone!
