It must be the power requirements within the motherboard bios, rx 480 was an 8 pin maximum, some rx 580 has 1 8 pin and 1 6 pin so in turn. mb bios is not accepting that cause mb power running amperage is way higher. The issue relies on motherboard bios, need to mod the motherboard bios for it to accept 6 cards or more. If you think about, it makes no sense why is not working. It should work. I advise you to try 7x rx 570.

No it is not MB BIOS. At same system (12xrig) I had 6x RX470, working like a charm, but now with 6x 570 it is not working. You will have all 6 RX 570 vga, you will install driver, and after that system will not boot in to Windows 10.
