oh okay, thank youNo there is nothing wrong with your cpu. The cpu uses the cores and speed it needs to get the job done. So in this instance 2.48ghz is all it calls for and it is only at 14% usage. If you play a heavy graphics laden game you may see it go too its max speed then. Or you could turn on max performance in windows power settings to keep it at it's maximum potential, or to see it work at that speed to see it working to your satisfaction. And you can always return it to balanced power setting after that.
