For me I used to setup the rig with one card, then move it to my mining shelf and hook up the other 3 GPUs. I used to have your problem all the time. Sometimes I'd get 4 cards, sometimes 3, sometimes 2. Now I just hook them all 4 GPUs from the beginning and install the OS. Never had a missing GPU in device manager this way. |
