So I have a 7900XT that will bootloop on my Asus ROG Strix X570-I Gaming. I install the card and I will not get a boot screen or anything to even access the bios. What does work is putting in my 6800XT and switching the pci-express to GEN 3 (The card is directly plugged into the motherboard no riser). Then reinstalling the 7900XT and everything works like normal. Im not bent out of shape having to run GEN 3 but what I am bent out of shape about is if the bios ever needs to be reset or does a reset for whatever reason, I will have a none booting computer until I switch back to the 6800XT and switch back to GEN 3 which is a massive pain being a ITX build. But here is also a wierd issue though, my Gigabyte X570 I AORUS PRO WIFI has zero issues running the card in GEN 4 and booting and working normally. Also i have the latest bios on both motherboards. Also the 6800XT runs gen4 pci-express on the Asus mobo fine.
