The CPU touts an on-board thermal sensor and real-time thermal monitoring. It also supports Dynamic Frequency Shifting (DFS), a technique that lets the CPUu operate at reduced power usage.
The upgrade works with Power Mac G4 AGP Sawtooth, Gigabit Ethernet, Digital Audio, QuickSilver and QuickSilver 2002 models. It’s compatible with Mac OS 9.x and Mac OX v10.3.5 or higher. Thermal monitoring and DFS features require Mac OS X v10.3.9 or later.
