Intel SpeedStep Technology
Intel SpeedStep technology allows the system to operate in multiple performance states. Intel SpeedStep
technology offers two CPU/system operational modes:
Maximum Performance Mode: Maximum CPU Core Frequency.
Battery Optimized Mode: Reduced CPU core frequency to extend battery life.
Intel SpeedStep technology transitions states only when AC power is connected or disconnected. It
transitions by changing the CPU PLL multiplier, which can only be done in the Deep Sleep CPU state
(clock going to the CPU is stopped), which is the C3 CPU power state.
Most of the control for Intel SpeedStep technology is done in the ICH3-M. However, the MCH-M must
cooperate on certain functions.

MCH-M Clocking
The CK408 compliant clock synthesizer supports the Intel 845MP/845MZ Chipset. For details refer to
the Intel Pentium 4 Processor in the 478 Pin Package and Intel845MP/845MZ Chipset Platform
Design Guide.
