Overclocking:
We used latest MSI AfterBurner, GPUz and our benchmarking suite to test the overclocking and stability at the highest possible clock. Fan and voltage settings were left on default during overclocking. Please note that every card overclocks to a different level, our testing should only be considered as a guideline to what you should expect from your card.
Overclocking the Club3D Radeon HD 7970 royalAce was pretty straight forward. I kept on increasing the core clock with increments of 10 MHz and testing the stability until it reached 1170 MHz. With anything higher than that, the graphics card stated to show artifacts. Same procedure was used for memory overclocking and a minimal increment of 40 MHz was achieved. Surprisingly, tweaking the fan speed was not needed even after a 20% overclock on core as the fans were intelligently tweaking themselves according to the heat output.
Let’s see how the Club3D Radeon HD 7970 royalAce performs with core clock set at 1170 MHz and memory set at 1540 MHz.
