Windows with the latest updates removed cards limitation you can run 12 Amd cards and 8 Nvidia cards. Also both AMD and Nvidia released latest drivers to support this after Windows did. The problem is from the ASUS side, they need to bring a Bios update (and I hope it happens soon) as this motherboard is a big power saver, rather than buying 3 times CPU,SSD and Motherboard, you buy them only one time. Meanwhile be happy with 13 cards max until Asus release the bios update.
