For our manual overclocking tests, we used MSI Afterburner. Our best results are as below.
When overclocking, we were able to add 220MHz to the GPU and 1580MHz to the memory, with the power draw slider at its maximum of 110%.
This overclock did see performance improve by a handful of frames, but it didn't do quite as well as the Aero OC – but once more, we're only talking about a difference of 1-2FPS, so it's really not noticeable in the real world.
Finally, power draw did increase as a result of the overclock, hitting 242.2W, a 10% increase over stock.
