ParkControl 1.3

Tweak CPU core parking and frequency scaling in real-time
3.7  (12 votes) (See all)

Core Parking is a technology rather similar to frequency scaling, as it attempts to throttle the CPU when idle. The major difference is that this sleep state will dynamically disable CPU cores in order to conserve power when idle, and re-enable the disabled cores when the CPU load increases once again. Core parking is supported by most newer x86 processors and newer editions of Windows. As handy as it can also be, disabling core parking is proven to make a real difference in system performance, and this is especially important for those who care more about the system performance than the power saving. ParkControl is a small utility that enables you to change the core parking settings in a quick and easy manner. Using this tool you will no longer have to worry that the OS-managed CPU core parking can cause performance deficiencies.

ParkControl lets you tweak the CPU core parking status in real-time, using 4 convenient power profiles. These profiles include the one called “Bitsum Highest Performance” which lets you create a power plan that auto-optimizes your hardware for maximum performance far beyond the system default ‘High Performance’ power plan. Anyway, ParkControl Pro, the paid version of ParkControl, can automatically switch the power profiles when your PC goes active or idle.

ParkControl is also really easy-to-use. It's a great tool for anyone wanting to squeeze the most out of their computers.
