So after pissing about for 3 days I've gone back to stock Vega 56 bioses.

The Vega 64 bios on my cards did increase the hash but at the cost of way more power and hash drops 20khs and 1.2kw from the wall

Fine tuned the my cards on 56bios to 19khs without timing, And 20khs with timing pulling 950 w from the wall. Pool hash rock solid now aswell
