ParkControl 1.1.3



ParkControl is a lightweight designed to help users disable CPU parking without rebooting the system. Although it is very simple to work with, the tool mainly caters to advanced computer users. The interface is represented by a regular window with a well-structured layout, where you can select the power profile and enable or disable CP parking on AC and battery. The CPU status can be viewed on the right side of the screen, represented by two large meters. In addition, you can ask the tool to show park settings in the "Power Options" area. Committing the new modifications is done with the simple click of a button. However, there is no option to revert settings to default.


ParkControl was developed because core parking settings are hidden in Windows, but can make such a large difference in performance, particularly when there are bursting CPU-bound loads (the most common type).

Core ParkingCore Parking is a sleep state (C6) supported by most newer x86 processors and later editions of Windows. Core Parking dynamically disables CPU cores to conserve power when idle.

Disabled cores are re-enabled as the CPU load increases once again. This technology is very similar to frequency scaling, in that it seeks to throttle the CPU when idle.

The problem is that Window's default power profiles are configured far too aggressively when it comes to core parking, especially on workstations.

Their interest was in conserving energy, even if this meant marginally decreasing performance. Some complex parameters control when a core should be parked, and Microsoft is geared heavily towards power savings.

The core parking settings in Windows are set as parameters of power plans (aka power profiles). That means you can, for example, disable core parking for the High-Performance power plan, but leave it enabled for other plans. And that is exactly the desired tweak for most users: disable parking only for high-performance power-plans.

ParkControl runs on a barely noticeable amount of CPU and RAM, so it does not affect the overall performance of the computer.

It has a good response time and quickly applies new changes. The tool does not hang, crash or pop up error dialogs. All in all, ParkControl serves its purpose and should please all power users.
