Re: EVGA GTX 570 overclocking issues.
I am not sure japgar, but I'll say this. I just rma'd my 570 SC yesterday because there is a low-volume, very high-pitched sound coming from it.
I have a new surge, changed the psu and a bunch of other things but the whining sound was still there and the tech identified it as likely being a capacitor problem.
It could be an issue with the quality of caps they are using in revision 1 of their 570 SC's which might be affecting over clocking beyond a certain level.
