These include a slight overclock and undervolt, they are intended for the OP1 CPU found in many chromebooks but have worked fine in all recorded cases on regular RK3399s in other devices.

Specific to the Pinebook Pro DTS in tsys' kernels is an extra clock speed entry for the big cores in <code>arch/arm64/boot/dts/rockchip/rk3399-pinebook-pro.dts</code><br>
It overrides the <code>opp08</code> entry for the big core cluster with one that runs 2GHz at 1.3V.<br>
It is up to you how to deal with this, either by just skipping opp08 in the main dtsi to keep using that entry or by removing that entry from the Pinebook Pro dts and adding your own to the regular dtsi.

TuxThePenguin has found that the RK3399 in his Pinebook Pro can reach 950MHz on the GPU while being stable.
Segfault has found that the RK3399 in his Pinebook Pro can reach 950MHz on the GPU while being stable.


The stock speed for the GPU is 800Mhz

The highest safe voltage for the little cores is 1.2V and for the big cores is 1.25V.
The highest safe voltage for the little cores is 1.2V and for the big cores is 1.25V.


TuxThePenguin has found that the little cores on his RK3399 can run at 1.6GHz, and 2.08GHz on the big cores.
Segfault has found that the RK3399 in his Pinebook Pro can reach 1.6GHz on the little cores and 2.08GHz on the big ones.
 
The stock speed for the little cores is 1.4GHz and on the big cores it is 1.8GHz, however the OP1 speeds default to 1.5GHz and 2.0GHz instead.
