Has someone succesfully tried to get 2x vegas 56, 2x vegas 64 working together with 2x rx570 + 2x rx580 on the same rig for mining XMR?

I am able to use the xmr-stak-amd miner and recognize all 8 GPUs. But when I try to use Hellms tweak of double threading the vegas (page 26), the Hash doesnt go up and Im stuck at ~ 750 H/s fo revery card, regardless of vega or rx580/570 and also without any effect on the intensities i put (2016/1600, 1000 or any combination).

I have blockchain drivers and win 10.

Thank you guys!
