I have encountered the same problem.
I suggest you save the data. And reapply them after "restore default"
Restoring default settings usually occurs after a system power outage / Windows update / drive hang or other problem
I tried to solve it... I have not found a solution at the moment. According to my observations, I think this has nothing to do with "power limitation."
But I still recommend that you report this to AMD.
