I will try...
Now I'm running back at perf-. It's ok with 2 hashboards, its showing and running good.
I've tried on factory mod (I was running for a week on this mod) but no signal of chain1 now.
Other modes the hashboard does not work. I've tested with only this hashboard connected, and the miner do not start mining. Just to remember, the others two works well.
