put together a skylake system but the 1 x pci-e slots not seeing the Ageia physx card. however if I put the phsyx card in the pci-e x16 3.0 slot and use onboard 530 graphics physx works perfectly..... don't want to do that with a 1070 waiting to go in. I tried an old usb 3.0 pc1x card and it worked fine so slots are working. Maybe physx old 1x card not compatible with newer 3.0 1x slots? Yes I know it's old tech just trying it out,,, Sometime you got to chuck the old....... Anyone know about this?
