We used AMD Wattman for our manual overclocking. We started off by maximising the power limit (up to 115%), before settling with a maximum frequency of 2400MHz. The card was stable with 2500 or 2600MHz dialled in, but actual frequency diminished slightly as I pushed passed 2400MHz. It was a similar story for the memory overclocking – my card was perfectly stable with memory frequency set to 2150MHz, but I found performance was slightly better with it set to 2100MHz.
This overclock resulted in performance gains of about 5%, so not hugely impressive here.
Power draw, meanwhile, increased by 15%.
