Where are you getting the readings from. In the bios it will never go in the boost. In windows it will never get into the boost unless you force it too. The other thing do you have the turbo boost enabled in the bios?
Like I said that unless you do benchmark or force into the boost that is what you will get. Because the boost is enabled it doesn't mean that it is going to run that way.
There are programs that you can use that will help. Here is a video on one. Like I said it doesn't run turbo boost all the time only when you need it. Other then that I don't know what else to tell you.https://www.youtube.com/watch?v=ZEj8miRM8po
