I found this software called ParkControl free to download at

Does adjusting the setting of core parking improve performance? Does it damage the processor?
No it does not improve performance. If you were using those parked cores, they would not be parked to begin with. And when you do use them, they unpark without delay.
Second, can it damage the processor? Unlikely but possible. A parked core is sleeping, using very little energy and generating little heat. An unparked core will use more energy and create more heat.
Nothing more then snake oil. Fiddling around with core parking will do nothing concerning performance.
