Quite a few enthusiasts use some sort of tool to control their graphics card. There are hundreds of monitoring tools out there, but only a handful provide complete control and interaction with the card. Club3D’s main goal with the royalFlush was to provide users with more overclockability, allowing them to unlock even more performance and tweak the setting to boost efficiency.

The basic features include monitoring or adjusting the core and memory clocks, temperature, fan speed and voltage. Users can save five custom profiles, which can include different values for core voltage, core clock, memory clock and fan speed. The UI is intuitive and simple. The start window consists of the Main Window and Hardware Monitor.

The latest version of royalFlush supports dual-GPU overclocking. When you have two different GPUs, you can select the one you would like to adjust and then tweak the core voltage, core speed, memory speed, and fan speed. From the general page of setting, you can also select the “Synchronization” to synchronize the two different graphic cards settings of core speed, memory speed, and fan speed.

Our HD 7970 XT2 ‘13Series sample was quite overclockable. We upped the GPU base clock from 1050MHz to 1160MHz. Overclocking the core by an additional 110MHz was a pretty nice result, since the card already runs 50MHz faster than the reference 1GHz. After our overclock, the GPU Boost did not come into play. We squeezed out another 100MHz from the memory (400MHz effectively).

We had no need for manual RPM settings, not even after overclocking, because auto-regulation ran just fine and temperature never exceeded 78°C.
