ventured into the NTool as pointed out by dragonmike above

WHAT A GREAT TOOL!!!

the best function of all is being able to save the settings under different labels so as to adjust all or each vega

45.5Mh on all is unstable, although great momentarily as there is a jump of 1,8Mh/s on every card for a total of 14,4Mh!!!

i tried tweeking this card or that card but the result was not reliable albeit due to shortage of time i didnt spend too much time on trial and error

it seems these multi PCIe mobos although advertised as able to run under such heavy busing stress, can only deliver on less powerful cards and cant take more than 4 boosted VEGAs STABILY, still waiting for driver update on mine

the Asrock again seems to preform better with multi gpu's, Thamez is more accomplished than i with electro-electronics

----------------------------
my SOLUTION was to restart, open WATTMAN, apply the old settings on all cards (1100mem, 1000cpu,-24%) which give a stable 43.7

then open NTool and mod the 1st 4 cards in the NTool selection tab,
these seems to make a difference for me as its the last 4 that were having issues when i was testing 45.5 on all

this way i get a steady and stable 4 cards on 45.5 and 4 on 43.7 for a tot of 357Mh/s or 2% boost on previous speeds
wattage seems unaffected around 1800

thnx for the tip dm
