Published documentation and sales pages have stated that clock speed can be raised from 400Mhz to 500Mhz using on board power supply options. Other sales pages have mentioned 600, 700Mhz, the indigogo listing states: " overclock to 800MHz, it offers 0.5TOPS"
I have not found any guidelines from kendryte on the subject.
Is overclocking practical?
Is overheating the limiting factor?, would added heat sinks help?
(I don’t find any info on internal temperate sensors)
Has Sipeed done substantial testing at 800Mhz?
