New miner here, two weeks in. Running SMOS, we've been running 12 x rx580's for a week now at about 30 MH/s on all 12 cards with ZERO restarts. I'm using a 2400W server PSU running on 240V. When I try to plug in the 13th rx580 into the PCI-e x16 slot, I get a black screen and nothing else. I thought I could just plug the PCI-e x1 riser into the end, but apparently not. I've tried at least 6 different riser combos and nothing. I tried plugging only ONE GPU into the PCI-e x16 slot and same back screen. Any ideas would be GREATLY appreciated!

is your main display set o IGPU or maybe set to auto or PCIE x16 slot?
