So, it held nice at 575. Overnight I lost internet, then after net came back it got real bad. One board was only at 25 degrees and hashing was down to like 3.4. I tried setting back to 550 and no luck. Then I did a "reset" within the hardware and it came back, but strangely defaulted to 700m.
It was using 1575w at the wall, and speed was low 4s, with errors like 0.7500. So I turned it down (up from original) to 600m. It hanging at like 4.4-4.9 and errors at 0.0115%.
Anyway, any thoughts on what happened? I thought I burned out a board or something??? Was that a sign not to go above 550?
Sometimes the boards will just stall out like that. A power cycle will bring them back, it is common with the S7. If your factory reset defaults the speed to 700 that means someone has flashed the wrong firmware. They used a newer 45 chip firmware, which always defaults to 700. I would look for the latest 575 firmware and flash it like that because running your miners at 700 will burn them out if they are the old 54 chip models.
