Did you try to switch between risers and PCI-e slots on the board? Sometimes switching things around fixes it.

If you have only 1 PSU EVGA 850 GOLD you are really lucky that you are mining with 5 cards. Forget about the sixth one because a 850 watt PSU doesn't support 6x RX 580 GPU-s.

Also rather than trying different settings in BIOS, why just you don't update the BIOS to latest version in case you haven't done so. GEN1 and above 4G should be enabled like you have done if you have more than 4-5 GPU-s.

Riser should be changed when mining become stuck, 90% of the time is because of a bad riser, bad driver or overheating not because it is not mining in GPU-0.
