Hello everyone.
I have 2* 3090 running on riser, when i want to add the 3d one i have à Black screen when powering and no signal is détected on the screen. I need do a cmos and run 2 only cards.
I use à AMD athlon 3000g as processor ( very low watt consumption)
Any one have an idea of what is going on ? How can you guys run more then 2 gpu on this motherboard ?
