run the 1200 reg mod

started CAST miner and my 6 Vega 64 incl mobo and screen are pulling 2000W from 1300W for an added 100H on total
obviously not a winner, as suggested by OP each to his own sweet spot, i must fiddle a little with the values
or
i just settle with 10% less at 1989h/s/vega64 which is what im mining ETN with at the mo.
then again
Total 12 x VEGA64 @23987 (@2600W) +10%(with above hex table)= +2400H/s = +1.1Vega64
hmmmmmmmm
