Good that it worked, but it is not exactly a new behavior for antminers.
In fact, S1 and S3 on many machines also had errors with PSU hard reset and had to be rebooted into a "better state" by a software reboot and sometimes multiple of those (especially on S3).
I am interested in some other parameter-what is the optimal board operating temperature that miner is reporting in gui.
Somehow it looks like it throttles back by itself as soon as it reaches 56C or so, at least on my machine.
i don't see much difference in hashing at 51C vs 55C with ambient around 28C. I wonder what others had observed.
well I can test it right now. I will lower fan speed which will raise temps.
you want to see 58c do well:
So here is fan 55% freq 600 temps at 53 all good after system reboot.
I will drop fan to 45% which should get the gear over 58C

and after 1 minute I am running at temps of 53 54 54 and my errors are 0.0401
after 3 minutes I am running at temps of 55 56 56 and my errors are 0.0286 and hash rate is 4553
I will let it run for 15 minutes I may need to slow the fans more since I seem to be at temps of 55 56 56
It has settled in at 4712 gh
temps of 54 ,55, 56
errors of 0.0240%
fan speed is 45%
so I will drop the fan speed to 40%.
https://i.imgur.com/eN3QQ3g.pngwith fan speed at 40% freq at 600 temps are now 58 58 59
I am hanging in with 4717 errors are 0.0201
so far testing seems to show keep your temps at 52-54c or lower. I will run this at fan 40% to see If it gets better or worse then below.
Fan 55% gave me cool numbers and good hash rate.
