in reality, modern processors are able to reduce frequencies much lower, it just happens at such a speed that no sensors or programs can monitor this, and don’t forget that the operating system also consumes something, and from this frequency constantly float, in fact, as I already said, there is no need to set the Gauge to the processor frequency; to effectively understand its operation, it is enough to set the processor load, and simply leave the frequency as a frequency number.. the panel is not an oscilloscope and not an accurate instrument for measuring vibrations the earth's crust, this is just a way to visualize processes..
