GTX570 safe voltage? - Page 2

post #11 of 27

But I played Metro 2033, Crysis Warhead and Crysis 2 without any problems.
Also, bc2 is more CPU intensive.

Why are you okay with it not being stable in a certain game? For me stability means stable in absolutely every environment.

This includes both CPU and GPU.

Use OCCT and test your GPU for errors with a 15 minute test. If you get a lot of errors then you need to tone down the clocks or raise the voltage more.

I'd also suggest trying a 1 hour CPU test on OCCT if you aren't sure whether or not your cpu is stable. If it passes 1 hour then you can run a 12+hour prime 95 blended test

First it didnt pass at 880/2100 1.05v, then i changed it to 880/2000 at 1.025v and it passed 15 min gpu test.

After all I decided to downclock it to core 850mhz, mem 1950mhz and 1.013v.

Still not that bad, but i agree stable should be a term used for something thats rock solid.

safe voltage for 570 GTX entirely depends on the type of 570 you own. Reference 570 has a got a pretty weak vrm circuity of 4+2 which makes it 4 for GPU and 2 for rams. For a reference card I say max is 1.1 and you better not go any higher. However, there are custom 570 gtx from different brands with improved VRM circuity such as Gainward 570 GTX Phanton or Palit GeForce GTX 570 Sonic Platinum. These cards have a strong 6+2 VRM circuity which makes a world of difference !!
I got my 570 GTX Phantom a few days ago, I have to say the usual OCing issue with 570 reference cards is gone for good in these custom cards. this card response well to increased voltage !
I reached a 960/1920/2300 on my card at 1.13 vlotage and its rock solid stable and vrm are as cool as morning breeze ^^

Running 1.1V since I bought my reference card about 2-3 months ago now, at the clocks in sig (were in my sig!) 900/1800/2000. Temps in my case are amazing though, and my card rarely, if ever, surpasses 65 C, which I believe helps. I really think you have to keep the entire card cool with these 570's. The VRM's are basically exploding on some cards, and I bet keeping the entire card cooler (back of PCB, etc.) should help prevent, or post-pone, this from happening. I've kind of been noticing that many cards that died had been hitting temps of 80+ C, and just wanted to be on the safe side.

Just going to ask if you are sure your CPU overclock is stable (if it is even oc'd)? The only reason I ask is because I was playing Medal of Honor multiplayer (same engine as BC2) and was surprised that my pc locked up.

I know for sure that it was my CPU because I've had it happen to me before in the past when I went for 4ghz. I just boosted the voltage a bit more for the sake of stability. I was stable in everything before touching frost byte engine as well.

Basically what I'm saying is that your lock up could be potentially from your CPU and not GPU.

I have been folding 24/7 on my EVGA GTX 570 for about a week now. 1063mV and 890 on the core. And still working like a charm.

As pointed out earlier, it helps keeping it cool. I run my card on water. Load temps rarely exceed 40C, idles at 27C.

The CPU is ok, i have tested it many times with prime95 and other programs. This week I'm going to change to Intel, so the cpu is not and wont be a problem.
