Hi my cpu frequency keeps changing from the lowest it will go like 0.8 to the highest 4.1 and sometimes random frequencies in between when im idle . It also does this when I have a game open and I am in alt tabbed too. I cant check while I have game in full screen (if it is different) because I have one monitor. Is this normal, if not how can I fix it. I have a i5-8600k and asus z370-p. I gots these numbers from core temp
