Hello,

I have this motherboard and is working ok with 6 cards, but I have extra 5 cards and the prices of the motherboards that support 12/13 gpus are pretty high right now, so I bought an PCIE extension. The issue is that when I plug the risers in the multiplier, the cards are not detected, but if I plug an usb stick, it works fine. Is because of the motherboard?

The riser interface is not USB3.0 it uses the connectors and cables but is not usb.. so you want a card more like this...

This will work with risers to gpus. Note that your cpu pcie lanes, chipset, other intefaces turned on in bios can all affect how many gpus you can actually get to recognize. If your bios has above 4g decoding then chances are good you can run more.... Its a try and see thing most of the time.

But usb3.0 plugged into a riser would present problems as the usb 3.0 is not compatible and carries voltage where risrs using usb connector/cables pass no voltages only data. Its just usb connectors and cables are cheap and reliable so used for this application also.

Thanks, it has 4g decoding, and it detects 6 gpus. Would the below work, as on amazon they are all available from april at soonest here in UK ?

Yeah thats same multiplexer. And they are inexpensive. Recently ive had to use several on rig where gpu0 had to be in slot but the other gpu slots where blocked. i just toss it into an unobstructed slot and plug in the gpus on risers. Ive had a cou0le boards that wouldnt go beyond 6 gpus but others do...depends on chipset / cpu pcie lanes / m.2 utilized ports etc.

Good luck and let us know if it works for ya.
