Alright actual question here.  Might be worth another thread.

I restarted my rig.  4/6 Vega 64's are hashing at 1900+ still.  2 are not.  No matter what I do with the HBCC slider for those cards, enable, disable, I cannot get the hash rate back.  The card is otherwise clocked correctly, I get the same ETH hash rate as I would expect. 

Any tips?  Full clean re-install of AMD drivers?  What I wouldn't do for some non-flashy software that would let you control these settings.
