I am having trouble posting. I have a b450F motherboard with a 2600X R5 and 8 GB of 2666 ram. I have duplicates of this as one is my testing board. I cannot get my 5700 Xt to work properly with this setup. My motherboard shows a white led light indicating vga. I have tried multiple slots and different ram amounts on both motherboards. Nothing seems to work and am getting same issue on both.
