For manual overclocking, we used AMD Wattman. Our best result came with the power slider maximised, the memory frequency slider maximised at 2150MHz, and a GPU frequency set to 2400MHz minimum and 2700MHz maximum. In practice, this resulted in the GPU running around 2450MHz.

This overclock resulted in performance gains of between 5-6% in the games we re-tested at 4K. It's not huge, but we found the same with the reference 6800 XT, and custom cards like the PowerColor Red Devil and Sapphire Nitro+ did significantly better, so it's likely going to be the same for the 6900 XT.

Power draw, meanwhile, increased to 343W with this overclock, an increase of 15% over stock.
