I just did my AM5/7800X3D upgrade yesterday and am using this board, I also have the same issue. I think it's with the type of "RGB lighting" Asus is using on this board. I can't remember exactly what it's called in Armory Crate, but you can control it separately in Armory Crate outside of iCue. You just need to uncheck the board from Aura Sync (if you're running more than just an Asus board), and then select the board from devices. There you'll see the RGB control for the board. Which is pretty limited if you ask me. I think I counted four different images it displays but you can't pick a static image out of those, when you pick a static color, it just defaults to a certain "ASUS" image. I also tried using just pure white as a static color, since it will go with every color but the white on this board looks purplish. Really disappointing. On the other hand, my Strix 4080 works perfectly in iCue. So did my Asus ROG X570 Crosshair 8 Hero.
