I have the same issue trying to run a 4x 1080ti rig stock, except mine just keeps running at 0 (maybe I killed it before it crashed though), no errors, just goes from 20k sols/card to 0.
Once and a while it will run for a bit but will crash if it looses connection (not sure why it lost connection, all the other rigs on that switch are still hashing away with no problems).
