Hi,

I am stuck in the RIG construction.
When I plus the GPU directly on motherboard, the system boot perfectly.
When I use a riser, the system does not boot (i can't even access to the bios). The fans of the GPU are correctly working.

I spend time checking every seting in the bios but do not find anything obvious.

MB : MPG Z390
riser : https://images-na.ssl-images-amazon.com/images/I/81A0nbQZyuL._AC_SL1200_.jpg
GPU : RTX 3070

I try to change the GPU and change the riser (all the components) without any change.

If you have any idea on how I can use the 4 PCIe slots on the MB, I am stuck :-/

I just command other Riser (another type) but 3 weeks delivery.

Ben
