So i already did this, only two of my three hashboards show status? Am i effd? I am also running 2 bitmain 1600W psus to run my antminer and it is on low power enhanced. It seems like its the only setting it works on. Somebody help!
2 x 1600 is a lot of overkill. Did you have 2 of them plugged into 1 board or did you have 1 running 2 boards and the other doing 1?
The danger of running on 2 psu's is 2 fold.
1) If the one running the controller goes offline the fans stop spinning. The hash board that still has power now has no cooling.
2) If you plug 2 separate psu's into one board you are now feeding in 12V from 2 separate 12V rails
With that being said. You can always try to revert to an older firmware:

Now that the lawyer talk is done.
I have not installed the new firmware but I have had it with some of the older ones where 1 board would drop out and going from firmware to firmware would fix it eventually.
