I got what I think is a batch 2, Z9 mini 5 days ago. However it has the Sat May 26 20:42:30 CST 2018 firmware and has the over clocking values instead of "Balance". It will overclock to 675, but is unstable after that. Averaging 14.9 KSols. I have only one Z9 on a bitmain psu, running 240 volt and it is drawing 364 watts with the fan on 100%, at the wall. Average temps 57-58c. The room it is in is not cooled and yesterday it was 95 degrees F in there.

The question is that it is getting 1000's of discards per hour, is this normal? On Suprnova at the moment. Good or bad?
