I've been trying to assemble a mining rig using this B450 Tomahawk Max II motherboard, this MOBO has five pcie slots and the problem is only four slots works no matter what I try, driver always crashes when miner is starting with 5th graphic card onboard, I've tried all risers and GPUs in a separate mobo they all work flawlessly, help.
What cards, which miner, OS? Above 4G is activated in bios
You have and old motherboard with H81 chipset - here you can´t find this option i think
