I have an issue where my Avalon 741 is only hashing at around 3.6TH for some reason.

It is running off a Bitmain 1600W PSU so that is not the problem.

From what i can see from the log, 2/4 of the MW pieces are all 0, which i assume means that they are not hashing, which would explain the 50% speed.

I've updated the firmware, left it running with and without the controller plugged in, attempting to reset it somehow but it the issue still persists.

This is the log:
