While fast, some users may want to run the mobile device to run faster, and apparently there is room for speed improvement in HTC Evo 4G.

coolbho3000 from the xda-developers forum has manage to overclock the HTC Evo 4G to run at higher frequency of 1.267 GHz instead of 1 GHz, which is more than 25% boost in CPU power. While overclocking is nice, the device will run overvolt on higher frequencies, directly draining the battery life faster, and the device is hotter too.

The to overclock HTC Evo 4G to 1.267 GHz has been released, and it requires a root HTC Evo 4G in order to apply the in recovery mode. The packages a special overclocked kernel.

The also includes an undervolt, which makes the HTC Evo 4G to run at whole 0.1V lower when idle, and can help to conserve battery life.
