Hi
Why minimum CPU clock speed for my processor (i5-3570K) is 1.6GHz, I know the system control the clock automatically but Why the system is idle the minimum speed is not nearest to 1Hz and keep on 1.6GHz?
I know exist limitation to increase the processors clock, also exist limitation to decrease it?
