Had a friend with a Q9550 and gamer Asus mobo, he was always saying something about it doing the turbo boost without any adjustments from him, it was automatic. The Q9450 is identical basically except for being a little slower. I have a new sealed QX9650 that I haven't touched as was hoping it would sell.
Any way, I got curious, and tried out an old program I used a few years ago called WPCUID, it has two functions, to id the the processor if I recall, and the WCPUCLK portion was for displaying the actual cpu clock speed in real time. Only the WCPUCLK portion was working in W7 64 and that's all I needed. It displayed 2.666~ ghz no matter what FSX flew over. The task manager would say 25% of the quad processor was being used, in other words the first core was close to maxed out while the other three would have regular spikes to max activity. Forgot, have to do Don's fix to have all three other cores working harder.
I was expecting the processor speed to routinely increase/decrease depending on the back breaking processor load I put on it. What is missing to get that turbo boost feature or was I misunderstanding the hardware required for that feature? My mobo is plain vanilla, not adjustable or overclockable, however I was told the turbo boost feature is a built in feature of the processor and doesn't need any outside adjustment. Is this speed stepping? Where am I going wrong?
