1) Normal. Ryzen processors are much more efficient than previous models and can operate at higher speeds and lower voltages. Also with Windows 10 the states of the processor can adjust very rapidly.
2) Normal to have a load temperature in the 50s, the thermal max is 90*C.
3) Without knowing what "auxiliary" is, we can't tell you if it's normal or not.
Thanks for the reply.
1)So I can not go below 2055? on fx in idle I went down to 800mhz I think, I would prefer it for the daily activity not very intensive.
3) I don't understand that component or part of the mobo refer.
