Overclocking is not a stranger to me. I overclocked my old Intel Core2 Extreme quad-core processor QX9650 to 3.6 GHz. And I can overclock my HTC HD2 with SetCPU’s help too. SetCPU is CPU speed tweaking application for Android. In details, it allows control of certain aspects of the Linux cpufreq driver by allowing for overclocking, underclocking and tweaking speeds. It works on most rooted Android 1.5, 1.6, 2.0, 2.1, 2.2 builds.
