Looking at this DTS file as well, "cluster1" labeled in the first file can be determined to be the A72 "big" cores. The A53 "little" cores seem to be running up to the factory specified 1.5Ghz.

I don't consider that an overclock. The diminishing returns part must've refered to the big ones, unless the little cores can't work in tandem with the big ones? I doubt that 2 cores beats 4, or that overclocking the smaller ones is pointless.

So the small ones overclock?

This sets an operating power point of 2.0 GHz @ 1.3V.
I wouldn't go higher than this, it's already at the point of diminishing returns.

Official RK3399 documentation states that the Cortex-A72 ("big") cores can go "over 1.8 GHz", which is rather vague.  Having that in mind, what should actually be considered an overclock?

May 2021 update: Manjaro ARM no longer overclocks the PineBook Pro's RK3399 SoC.
