More than likely im guessing i didnt get that great of a card. its a gigabyte gtx 670 2gb. i have a very small kepler boost of around 35mhz. im trying to find my max core overclock using evga precision x and heaven benchmark. i set the voltage to max (1.175) and power target to max (112%) so far all my monitoring charts are completely straight when benchmarking. my temps never go over 55C and my power target is always below 80%. everything other than my kepler boost seems fine. im able to add +111 to the core which gives me about 1201mhz max core. but when i take it to +121, heaven crashes even though all my monitoring charts are stable. i have no idea why it would crash when everything seems to be running fine. im using latest drivers (310.70).
