Safe overclock voltage settings for GTX570?

[killazys]

I have the MSI Twin Frozr III. If I set all voltages to maximum in afterburner (+150mV core, +50mV mem, +30 aux) I can get 950/1900/2300 stable. But those voltages really worry me, and I haven't been able to find any literature on whether or not it's safe to max out GPU voltages (they're limited by... something, it seems).

Any input?

I personally would not max out the voltage. 900mhz would be a pretty good overclock, giving you better than gtx580 performance. You'd probably get a fairly significant drop in voltage if you backed off that last 50mhz.

925/1850/2200 now.. +125 core, +30memory, +0 aux seems to be stable. A lot less than before..
