Overclocking
The Classified is as primed for overclocking as any air-cooled card we've come across of late. Running past Nvidia's voltage blocks can be achieved in two ways: use the optional EVBot hardware or opt for software-based tweaks. We decided to use the latter by harnessing a program called GTX Classified Controller popularised by the guys over at Overclock.net.
Classified Controller allows us to raise the GPU's voltage to a maximum 1.3875V, which when allied to the maximum power target of 115 per cent and 94°C temperature target should make for great overclocking. Trouble is, there's a fine line between voltage (power) and GPU throttling. Playing around with the voltage and examining performance gave us the optimum combination of 1.2875V and maximum in-game speed.
The end result? A base clock of 1,218MHz and memory at an effective 7,678MHz. Yet base clocks, as we have shown, are semi-meaningless. Running the card through our games highlighted that the core ran at a steady 1,384MHz when at full chat. Yup, that's fast.
Already rather tasty in the benchmarks, the rampaging frequencies give it the highest single-GPU scores we've ever seen.
