    Is something wrong with my CPU?

    I have a Intel Core 2 Duo T7500 but when i use CPU-Z, I get a core speed of 798 MHZ (fluctuating sometimes to 2100ish) and a rated FSB of only 400Mhz. How do I make it stay at the maximum core speed when its plugged in and how do I get the FSB speed to 800Mhz, the santa rosa standard?

    To make it stay at the maximum core speed you'll need to adjust your power settings. As far as FSB is concerned, I don't know. I don't know why you'd want to have it ramped up to the maximum multiplier all the time; that just wastes energy and creates heat. The computer is smart enough to know when it needs full power.

    Your CPU is acting normally. The Intel chips use a feature called "Speedstep" which reduces the clock speed of the CPU when it is idle and scales the speed as needed. If you run something CPU intensive, then your CPU will go up to its maximum speed.

    If you want your CPU to always run at max speed, then you need to go into the power options in the vista control panel and select "Max Performance" as the power scheme.

    The Core 2 Duo has the ability to dynamically adjust both the FSB and multiplier (as well as voltage) to reduce power consumption and heat while under low loads. Because it automatically clocks back up to full speed under significant load, there's no need to manually set it to full speed. That just wastes power and generates extra heat for zero actual performance gain.
