That's what I followed when I got it runing, but I was more focused on recognising and getting the 6 GPUs to work. I still couldn't get it to use integrated VGA instead. If I enable integrated graphics in bios and choose IGFX as primary display output, I lose both integrated and gpu and have to reset bios after that to get video signal. Have the same issue on 2nd rig with same config as I said. Doesn't seem like a deffective product.

Other than that, I use GPU0 for display, rig is working fine, mining is going well, it just bothers me that it's not right.
