The HW errors don't look like a problem but that reported hashrate sure does.  You might try swapping where the hash board is connected on the controller board.  My B3 has 4 connectors on the control board so there is an extra and I have seen another post where someone else said theirs did too.  Looking down at the unit from the top with the intake fan pointing towards you (what I would call the front) I believe that bottom chain in the GUI should be the right hand board.
