I received my 8th card yesterday and popped it in, turned on the computer and everything is all good. Bios version 0810, 006c risers, generic M.2 pcie converters and ssd running Windows 10 Pro. I did install the latest drivers from Asus for LAN, VGA, and I think chipset. I left audio alone as it's disabled. I am not sure if the driver updates are a must or not but I figured it couldn't hurt.
