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:

Standard disclaimer: If you are not sure what you are doing don't do it. If you mess it up and brick your miner don't yell at me. You are doing this at your own risk.

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.
