I've been having crashes recently due to power issues (as far as I can tell) and it's been very random but a little bit ago I noticed while using EVGA's precision tool to monitor my temps fan speeds ect. The card's clock speed was hitting over 1900mhz whic the factory boost clocki says its only 1755, I know it can hit higher clocks and all but the only thing I've done is mess with my fans to keep it cool under load, even when I use the default settings it hits these numbers, I'm running an 850 watt PSU but the card itself does draw around 350 alone if not more under heavy loads. Any idea what's going on here?
