We overclocked the EVGA Classified by keeping to stock voltages and increasing the core and memory. The higher-than-normal voltage enabled us to overclock the core to the highest we've yet seen on a GTX 780 Ti, all the way up to 1,145MHz (Boosting to 1,270MHz). Memory, too, scaled nicely, hitting 7,900MHz.
Highest on the core and memory, the Classified is pregnant with benchmark-busting promise.
Just as the standard Classified is about 10 per cent faster than a reference GTX 780 Ti, overclocking the card adds a further 10 per cent performance. Do bear in mind that system-wide power consumption rose to 390W and noise levels increased to 41.6dB.
Notwithstanding the high clocks, there's little point in the Classified unless you're going to push it further, much further. This is possible via third-party applications such as Classified Voltage Tool. We manually adjusted the core voltage up to 1.325V and memory to 1.7V. Voltage helps increase the speed to 1,171MHz core and 8,040MHz memory. Pushing the ACX cooler to the limit, system power consumption spirals to 479W and noise ramps up to 44.8dB... but this is compensated with scores of 11,902 and 6,022, respectively.
