For overclocking, we used Gigabyte's Aorus Master utility. We managed an extra +135MHz to the GPU core and +1000MHz (2000MHz effective) to the memory.
3DMark and games testing
This overclock brought impressive performance gains for the Gigabyte card. Not only did our Fire Strike score increase by 9.5%, but we also gained an extra 8FPS playing Shadow of the Tomb Raider.
Average clock speed under load
This is thanks to our real-world clock speed increasing from 1857MHz all the way to 2027MHz – an increase of 170MHz. We only managed to get MSI's Gaming X up to 2003MHz, which goes to show you don't necessarily need one of the top-end cards to achieve the best overclocks – though of course this very much card-dependent.
