I am using a Ryzen 3700x, 3rd gen.I might not have made what I was saying clear. Which CPU are you running? The list on their site says that any 1st/2nd/3rd gen Ryzen without graphics should work. i.e. a Ryzen 5 2500X does not have graphics and should work with 2 NVME drives, while a Ryzen 5 2400G does and will only accept 1 NVME drive per slot.
It sounds like I don’t need to pull the graphics card. I am not sure why it isn’t working then.
