    This works….MSI Z170a gaming pro carbon motherboard……
    But only thing is…..your windows 10 installation should be in uefi or it should support uefi in bios not legacy……windows hardrive should be in gpt format…..other wise the above 4g setting won’t work and u will get a black screen when u try to boot in to windows 10…….I used 16.9.1 driver for my amd Rx 480 nitro+oc cards

    My setup is
    MSI z170a gaming pro carbon motherboard
    Rx 480 8gb nitro+oc graphics cards
    Usb powered risers 1x to 16x for graphics card
    I5 processor(a cheap one)
    Ram Kingston hyper fx 16 GB 8×2
    Kingston 120 GB SSD
    Thermal take 1200 watt power supply
