Welcome to the forums, newcomer!

You forgot to mention the make and model of your PSU. What version of Windows 10 are you working with? Can you get into BIOS and remain there indefinitely? While there, check and see what BIOS version you're on at the time of writing.

Hey there - I hope you got this fixed since it's from a while ago. Risers haven't worked well with this MOBO since it's PCIE 4.0 compatible and risers are not. You have to go into the BIOS and customize selections if you are going to use the riser and want it to communicate with the older protocol.

To my knowledge, this works: https://www.amazon.com/LINKUP-RX6900XT-High-Speed-Gen4┃Universal-Compatible/dp/B08XN26DRZ?th=1

Also, the fault code it's getting stuck on is the "Post-Memory system agent initialization" so it seems like it's not a huge fan of your RAM. What's the speed? Brand? And do you have them in the proper configuration according to the manual?
