From what I can tell, very little help is offered by Asus on this forum. I have 3 Asus motherboards and Armoury Crate doesn't work on any of them anymore. 2 of them have never worked correctly and the 3rd is my newest AMD build. X570 CH8 and Strix 5700XT worked ok until the lastest round of AC updates. AC doesn't detect anything and when it does, can't change the lighting or patterns. Just stuck on random colors or rainbow. Just like the other 2 systems I have. Disappointing to say the least.
Performance wise, the systems run great so if your having issues, I suggest tech support.
The only way i found to deal with armoury crate is with a fresh window install, to stay away from ai suite ,aura and and any other asus software,they seems to conflict with each other. If any of these was previously installed, armoury wont work and prevent the other one to work properly.
Like other said its only software related ,your hardware is ok, take little to no time to do a fresh install these day .
