Hello, we have 4 rx480 cards and one rx470 cards connected to the mainboard with 5 rissers.The two of them are connected to the x16 slots,and the other 3 to the x1 slots.System boots,BUT it doesn't recognize the 470 card,only the others.Secondly the monitor blinks by time to time to black, and then opens again.Once we start minning the the system after some hours crashes and shuts down.What do we need to do to make it stable?We have installed all drivers, catalyst 17.4.3 from AMD and the drivers for Motherboard. We run the pc on its onboard gpu.Do you think we should run it from the gpu one?what can we do?what is the possible problem for the system to crash?

You missed to mention the most important part and the mostly causing this problem the power supply , it could be an insufficient power issue.
