The other day I literally burned my fingers when trying to figure out why my mostly idle bpi-m2+ did not respond.
Unfortunately I forgot to throttle the CPU/RAM with the h3consumption tool.

Which settings would you recommended for a M2+ in order to avoid overheating? To my surprise the overheating also happened without high loads.

h3consumption -m 240 -D 132 -c1

The 'engineers' of this Banana forgot to enable voltage switching so on this poor guy the CPU will be fed all the time with 1.3V. Simply downclock DRAM (helps the memory controller inside H3) and use only a single CPU core at 240 MHz max.

Thanks for your reply @tkaiser

Afterall it took me several month to realize that the M2+ is a useless piece of hardware. Guess you realized this ways faster ;-)
I won't buy any new M2+ board and most likely shred my existing ones.
