One of your boards is shutting off. It is probably on the edge of failure.

Look at #8.  0 GH's.

reflow some chip? like a notebook?
or just send it back to Bitmain and they repair the bad board?
I guess I can just unplug one board at the time and see which one is dying and let it unplugged meanwhile otherwise it will consume more electricity

thanks for your quick answer

Again #8 is the one that is failing.  Unplug one of the outside boards and see if it is still hashing at the same amount.  If it is, the unplugged board is the bad one...if not, the one that is plugged in is the bad one.

I'm debating fixing S9's, getting good with S7's. Does it run if you slow the clock down to 200mhz or so?
