core2-duo

My laptop has an Intel Core 2 Duo T9300 which should be running at 2.5GHz, however CPU-Z consistently reports my Core speed at right under 1.6Ghz (8x multiplier and ~200MHz Bus Speed). Even when I'm doing heavy development work and the processor is running at 100% for extended periods of time the core speed reported by CPU-Z never goes up to 2.5GHz. My understanding is that this reduction in speed is to save power, but this happens even when I'm plugged into the outlet.

Does anyone know why this is happening or how to fix it?
