Hey Horiizon, each chip differs... Basically, you'll have to keep upping the core and memory clocks with something like Afterburner or EVGA precision, until it becomes unstable. Then add more core voltage until those clocks are stable, rinse and repeat. Clock speed doesn't equal heat, core voltage does. So, given that your case has not too brilliant cooling, a mild overclock on stock volts should be fine :)
