if it starts automatically at startup:
Clocks are all the same. CPU Core Clock 1130, GPU Memory Clock 2150, cpu and mem voltages are 850mv on all cards (GPU-Z) | 780W from wall
GPU0 29.990 Mh/s, GPU1 27.928 Mh/s, GPU2 27.911 Mh/s, GPU3 27.916 Mh/s, GPU4 27.930 Mh/s, GPU5 27.975 Mh/s

if i start the bat file manually via remote:
clocks are the same: 1130 core, 2150 mem but voltage now differ GPU0 830mv, GPU1 850mv, GPU2 970mv, GPU3 930mv, GPU4 930mv, GPU5 970mv | 900W from wall and cant adjust the voltage via afterburner (i can choose -70mv but GPU-Z show me no change)
GPU0 29.979 Mh/s, GPU1 30.067 Mh/s, GPU2 30.007 Mh/s, GPU3 30.055 Mh/s, GPU4 30.004 Mh/s, GPU5 30.021 Mh/s

I have a problem. I have a 6x rig with Sapphire Pulse RX580 8GB, using Win10 and the mining driver. GPU0 have 30,5 MH/s and the other 5 cards run at 28 MH/s. I using a start.bat, wich executed (with the highest privileges) by the task planer from win10. It works with 780W from the wall. Why does GPU0 run faster than the others?
I tried to start the start.bat manually via remote desktop and run as an administrator and get all cards at 30,5 MH/s. Clocks are always the same, but the power consumption raise up to 980W from the wall (-cvddc and -mvddc doesnt work).

What can i do?
