GTX 570 beast 2.5gb overclocking

post #1 of 3
Thread Starter 
Hi,

I need your help figuring out what kind of "safe" voltage my GTX 570s could potentially get based on the pcb it has.
I own 2 Point Of View GTX 570 Beast 2.5GB, those cards have a custom pcb, and I have to admit that I don't know much into VRMs and PCB in general.

Here is a pic of the PCB


Those cards have a already the biggest factory overclock from 732/1464/1900 to 841/1682/1980 and I wanted to know if I can push further.

One card is at 1.038mv and the other at 1.063mv from factory.

Thanks for your help

Cheers
Tomalh

With good cooling, I don't see why you couldn't run at least 1.1v on the cards. See how far you can push them @ currently voltage, and then see how much more yougget from 1.1v. If it's not more than say 25-35Mhz, it's not worth it.

I agree with nleksan. Put them to 1.1v and see what you top out at. If its over 900 core I would say keep it.

1.1-1.15v would be the max I would personally put through a 4 vrm gtx 570 design and it looks like it's 4 vrm from the pic but I could be wrong.

I have rma'd my gtx 570 3 times since I've had it trying to go for 1ghz clock. Highest I ever got one was 955mhz @ 1.13v before it crapped out. Although I'm pretty sure it wasn't the vrms that caused the cards to die as I didn't see any popped vrms or burn marks on the card.
