Overclocking works really well on the ASUS RX 6800 XT STRIX OC LC. My jaw dropped when I passed the 2700 MHz boost setting in Radeon Settings, and it just kept on going and going. I almost maxed out the GPU frequency slider, which ends at 2800 MHz!
Increasing the power limit has no effect, the card already has enough power headroom at default.
