ASUS Maximus IV Extreme-Z not detecting 3 GPUS!!
Based on the manual for this board, 3 GPUs only work if you use slot1, slot 2 and slot 4 (2 and 4 use NF200 Nvidia chip). Currently I had a 1080 Ti in slot 1 and 2 RX 480s in slot 2 and 4 and all slot physical switches are in the on position on the motherboard. The power supply is a thermaltake 80+ Gold 850W unit, CPU is i7 2700k. However, the GPU DIMM Post screen in bios only detects the 1080 Ti in slot 1 and not the other cards. In windows, 2 cards are detected but one of the RX 480s has an error in windows and no drivers can be installed. Swapped out the 1080 Ti with another RX 480 for a total of 3 RX 480s in slot 1, 2 and 4. Again same problem!!
I also tried plugging 1 molex power in the board, no luck. The board is supposed to support 3 gpus simultaneously. So far only 2 GPUs work together in slot 1 and 3. Any help would be greatly appreciated.
