Manual overclocking has once more become more complicated with this generation. Since the cards are always running in the power limiter, you can no longer just dial-in stable clocks for the highest boost state to find the maximum overclock. The biggest issue is that you can't just reach that state reliably, so your testing is limited to whatever frequency your test load is running at.
With manual overclocking, maximum overclock of our sample is 2020 MHz on the memory (15% overclock) and +130 MHz to the GPU's base clock, which increases maximum Boost from 1980 MHz to 2040 MHz (3% overclock).
