I have an ASUS Z270-AR with Celeron 3980, 8GB DDR4, 1200 watt PSU, and 6 VisionTek RX570 GPU.
When I connect the 6th card in Win10, I go into a continuous boot loop and have to remove it to get anywhere. I have done all BIOS settings from the previously linked YouTube video for this board, but I cannot get more than 5 to boot and function. I also tried going to Gen1 for the aforementioned BIOS Settings with no luck. I am getting 130 Mh/s from the 5 cards, and would love to pop over 150 with the sixth.  Any advise would be welcome!!

I have VisionTek RX 570s with Elpida memory and I can't figure out how to get over 25 mh/s with BIOS Mods. Any suggestions very welcome.
