That is how it works, in theory. But it doesn't seem to properly recognize when it should run at full speed. Another user found that turning C&Q off dramatically increased his benchmarks, because the processor was not properly detecting a full load condition. If you're happy with the performance, than don't worry about it. Personally, I don't see the need for power saving features on a desktop. By turning that feature off, you are in no danger of overheating the processor.
Also, the multiplier should be 12-> 200x12=2400MHz
