Hello Wink


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. Roll Eyes Huh

You have an idea why my gpu is not detected?

thank you in advance

Your question is the same as this post - https://bitcointalk.org/index.php?topic=1703685.0 - You might want to follow this post rather than making a new one.

At some Asrock MBs pci-e x16 must be connected with pci-e x16 raser, not with pci-e x1
it can be powered or not - no diff, a cheap one will be ok

edit:
you can check even without a riser - just put a GPU in PCI-E x16 directly
if problem will be solved, so - use x16 to x16 riser to connect
