mfr said parts to seller next week. I love the miner, wish they sent spare parts with batch's. runs a sweet 56-66t on 2hu. normal mode.
Interesting. When one of my hashboards quit, the unit would do about the same ~50th/s but only for about 20 minutes before dying. Temperatures are misread, fans operate at incorrect speeds. Having 1 hashboard out essentially renders the whole unit unoperable.
Did you unplug the faulty hashboard?
