Overclocking
Overclocking the card to 940MHz increased the GPU temperature to 70°C with our gaming results increasing up to 11%. Bear in mind that each sample overclocks differently, so you might get equal, higher or lower scores depending on the card. We managed a 110MHz overclock for the GPU without meddling with voltages, because while this card supports software voltage regulation - current tools don’t feature support for that.
