I have a GIGABYTE B365M DS3H with 3 PCI slots and I bough a 1 to 4 PCI adapter hoping ti connect more GPUs. When I tried it, Hiveos only saw 3 GPUs. Is there a BIOS setting or anything else that I need to change to be able to connect more GPUs? Any experience with these adapters? I can still return the MB and get another one, if I know that it will work.
