Why is the p-state status MSR on ryzen not changing?
It may not be related, however I have heard that some people have successfully had their Ryzen 7s replaced by AMD, due to p states causing system stability issues in Unix or Unix like systems. Although from commentary on the matter, especially from ASrock forum points towards a driver/firmware issue, I have read elsewhere that AMD may be taking some responsibility with early batches of chips. That said from what I know of P and C states, some states are requested by the operating system, or host vertulisation environment. So a patch could be done from within?
