The Red Team 3D Mark Scores latest Thread has dissapeared in this new Forum and I still cannot get hold of a Big Navi GPU to test. Here is a video showing overclocking an RX6800 GPU. Just in case you all have forgotten how to do it or cannot even get hold of RX6800/XT GPUs yourselves.
Power slider on RX6800/XT only increases up to +15% which means they maust be opwerating very close to thermal limit already. RX Vega 64 Liquid / RX5700XT allow up to +50% Power Limit, for example. Still no idea how much Rage Mode increases the Power Slider by. Turbo on RX Vega 64 Liquid sets +25% Power Limit.
