For our manual overclocking tests, we used AMD's built-in tuning tool. Our best results are as below.
As with all RDNA 3 GPUs, you can effectively push clock speed as high as the slider allows, and how much extra frequency you get comes down to how far you can undervolt the GPU. In our case, this was with 1060mV and the memory at 2400MHz.
This saw our real-world GPU clock speed hit 2864MHz on average over our thirty minute stress test, so about a 250MHz boost over stock.
The actual real-world gains weren't overly significant however, as we saw around 6% increases to the framerate in both Cyberpunk 2077 and Resident Evil 4.
Power did shoot up however, coming in at just over 300W, so that's a 19% increase over stock.
