Yeah I try to run conservatively as in not going for max hash but best power efficiency:
TUBE = 1.35 kH/s pool side for 160w at the wall
tube-haven-heavy give 2000+HR on any vega (56 or 64) and use etc 150W per cards
etc: 1 rig 6*vega56hynix = 960W at the wall = 12200kh etc
1 rig 4*vega56 samsung = 720W at the wall 8700kh etc
I dont use a dedicated mining rig.. its in a PC and has to drive a monitor and be able to do productive work in the day time - hence stable clocks. If you can tweak better - kudos but its a ballpark
