For our manual overclocking tests, we used MSI Afterburner. Our best results are as below.
The Gaming OC sports a maximum power limit of 400W, so we increased the power limit to 125% and were able to add 220MHz to the GPU and 1700MHz to the memory.
This brought average clock speeds up beyond 3GHz, remaining rock solid at 3030MHz over our 30-minute stress test in Cyberpunk 2077.
The gains from this overclock are decent enough, but nothing too extraordinary – we're again looking in the 6-9% performance range.
Power draw did increase by 40W or so when overclocked, which works out as an extra 13%, reducing efficiency slightly, but nothing too concerning.
