It is overclocked,but with the cooler heat isn't an issue. I haven't pushed the voltage at all...Max voltage I ran was 1.79 volts, which is only .07 or so above stock which is nothing. The card can handle 1.30v or more without damage with proper cooling. I wouldn't sell a damaged card so let me know,thx
