Title: usb 3.0 pci-e riser no GPU/cards detected Post by: Aureliusy on February 28, 2014, 03:15:22 PM I upgraded from normal 16x16 and 16x1 risers to three usb 3.0 pci-e risers.
The GPU's /graphic cards are not detected at all with the usb risers. Fans are spinning Tried with one two and three usb risers. No effect. Tried in 16 and 1 slot No effect Reinstalled AMD drivers. No effect I did no try the jumpstart thing (because the normal pci 16x1 riser works fine) http://www.gobitgo.com/articles/1001/How-To-Correctly-Use-and-Install-PCI-E-Riser-Cables/ Maybe it is the usb3.0 cable or my motherboard(Asrock z77 pro4 m ) or? Any help is appreciated. Title: Re: usb 3.0 pci-e riser no GPU/cards detected Post by: dealio on February 28, 2014, 05:42:26 PM are molex power cables connected?

I was using regular powered risers and it was working fine. I switched one of the cards to USB Powered Risers and it doesn't work. I've tried 2 different USB powered risers with same result. Card is not detected. I've tried in Asrock 970 Extreme4 and Asrock H61 Pro BTC Asrock 970 doesn't have any Gen1 setting in BIOS as far as I can tell.

Title: Re: usb 3.0 pci-e riser no GPU/cards detected Post by: prelsidente on March 29, 2014, 12:16:32 PM In my case it was the USB cables. 2 out of 3 were faulty. 3rd was just badly connected.
