My visible hashrate on D3 screen is much better with fewer hw errors using this firmware. However, my shares/poolside hashrate is better with stock firmware. I've  ran 48 hour tests on the same pool using the same workers.

The only variable is the firmware, I wonder why this is so, because it seems very promising but for us not worth a 20% drop in shares.

This was tested using Blizz firmware previous version I have not had time to test this very latest. Anyone have insight on what could cause this?
