BTW, the control board has 3 ports for hashboards. Try swapping the cable of the the flaky hashboard to the unused port.
Should have read this thread before buying an R4. But I couldn't help myself.
So I have one from batch 5. 7.5 TH/s. It actually runs about 7 Th/s.
The first board tends to go dead about every 12 hours. But to look at the Miner Status screen it's hard to tell. See below. Everything looks fine. But Board 1 is not actually hashing. The only giveaway is the temps. But everything else about it is bogus! We re-flashed the firmware to see if that will help. Anyone else see anything similar?
