Hey guys just bought this motherboard and currently have 3 gpus on her. it has 2 pci-e 16x and 3 pci-e 1x. does it support more than 3 gpus? in bios, it doesnt have pci option for 1gen, which most motherboards do have, but this one was like 60€ and affordable, so if anyone can give me a tip about it :) thanks!

    A normal motherboard(not old 775 mobos) can support up to 4 graphics cards with no problem with x1 to x16 pci-e risers. But if you want to put more than 4 graphics cards on it you have to enable "4g+ decoding" in the bios.If it doesn't have that option...You can't put more than 4 gpus on it. but i think your mobo has that option.

    What worked for me, was enabling IOMMU in the BIOS
