Please list your builds specs with make and model#'s of the various parts, Which slot the Revo drive is in, and which OS you are attempting to run. Thanks.
Motherboard: Rampage IV black edition (bios updated to latest)
CPU: intel core i7 4930K
Ram: corsair vengeance low profile 16gb 2x8GB 1,6GHz
GPU: Nvidia geforce gtx 980, Asus Strix
HDD: WD black 1TB
SSD: Revodrive 350 480gb ssd-pcie
GPU is in first slot
Tried ssd in al remaining slots, not working
Also tried to put gpu in 2de and 3de slot but then i dont get a screen (fearing it is my motherboard that is toasted)+(in every slot the revodrive lights up)
Edit: OS i tried installing Win 8.1 from DVD and Win 10 from usb. none detects the hardware.
Edit2: Revodrive works in another much older system
