Hello

I have 5 gpu rx480 with motherboard asrock btc.
I plugged 4 card on pci-1 with riser xsource (powered)
It works very well.
Waiting to receive my 5th riser, I wanted to connect my 5th gpu directly on the pci-16 of the motherboard.
But that if is not recognized by wattman or claymore.

You have an idea why my gpu is not detected?
thank you in advance
