I CANNOT get this thing to boot with 4 GPUs on risers installed. It works fine without the risers. I first was using x16 to x16 risers, am now using x1 to x16 powered risers. It passes BIOS but windows does not load "your pc ran into a problem and needs to restart"
I've gone one by one with the risers and can't get past 2 cards, and even that seems finicky.
I have tried every BIOS setting I know of, booting full UEFI with above 4G encoding enabled. Any suggestions?
