PCIE Riser does not work

Hello Guys,

I’ve finished building my mining rig with 6x MSI Gtx 1070, a Z170A SLI Plus Motherboard, Win 10 Pro Uefi.

But for some undefining reason my Elegant PCIE USB Risers does not work. When I one card directly to the MB everything is fine but however not a single card is beeing recognized when I use the risers…

Getting kinda desperate at the moment.

Any tips?

Bios settings have been made but maybe you got some intel.

Found out that the Risers Vers 888 are bullshit and do not cooperate with my MB. So switching to some VERS 006c.
