On specific detail about the frequency scaling is that even if you set an index to 100% it'll increase (and keep) the frequency up to the CPU base frequency level, and still use dynamic scaling for any extra performance You can see an example in the image below where frequency scaling is set to 100% and the OS is keeping CPU frequency as close to its base (2.6 GHz in this specific example) as possible at all times. The index for this control works similar to Core parking. Similar to Core Parking OS is trying to scale CPU frequency dynamically based on the system load.

CPU frequency scaling is a feature that enables the operating system to scale CPU frequency up or down to try and match supply to demand, delivering CPU performance when necessary or saving energy when possible. Below you can find information about the way this application works and how to interpret application data and settings as well as modify and monitor other critical system parameters. Quick CPU is a program that was designed to fine-tune and monitor important CPU and System parameters such as CPU Temperature (Package and Core Temp), CPU Performance, Power, Voltage, Current, Core Parking, Frequency Scaling, System Memory, Turbo Boost, C-States, Speed Shift FIVR Control as well as making other adjustments.
