Monday, 20 June 2005 ThrottleWatch is a utility for detecting and reporting the CPU throttling activity in Pentium 4, Xeon, and Pentium M processors. ThrottleWatch monitors and graphically displays both the CPU load and any throttling that occurs. When ThrottleWatch is minimized, an icon is added to the system tray area of the Taskbar. The color of the icon changes when throttling is detected.
