I installed Asus’ CPU/fan monitor on my new AMD64 system, and I discovered that the system frequently changed speeds from 3.3 GHz down to 2.2 GHz. Very frequently. In fact, it spent most of its time running at 2.2 GHz. I decided to investigate, and found the setting was in Windows 7’s power management settings.
If you have a newer AMD or Intel CPU and Windows 7, you may find its power management settings aren’t quite as aggressive as they could be.
