I know it is in development. and only for testing. I have build armbian 5.51 ubuntu 18.04, kernel  4.14 . I have question. max cpu H3 speed is set up on 1100 mhz. All orange pi boards with the same cpu have 1296 mhz. I set up cpu governor on performance all the time 1100mhz. I achieved temperatures on cpu between 53-62 celsius degrees.  Could be the max cpu speed bring up to the 1296 MHZ? I have radiator 3.5 cm x 3.5 cm on board tritium H3. And it is not very hot.  thanks for reply.

Libre Computer chose to not implement any voltage regulation on these boards so no DVFS is working, the SoC is fed with a low voltage so no higher clockspeeds possible without crashing/freezing.
