5.3 Speedstep Technology
The Intel® Atom Processor offers the Intel® Enhanced SpeedStep™ technology that automatically switches between
maximum performance mode and battery-optimized mode, depending on the needs of the application being run. It
let you customize high performance computing on your applications. When powered by a battery or running in idle
mode, the processor drops to lower frequencies (by changing the CPU ratios) and voltage, conserving battery life
while maintaining a high level of performance. The frequency is set back automatically to the high frequency,
allowing you to customize performance.
In order to use the Intel® Enhanced SpeedStep™ technology the operating system must support SpeedStep™
technology.
By disabling the SpeedStep feature in the BIOS, manual control/modification of CPU performance is possible. Setup
the CPU Performance State in the BIOS Setup or use 3rd party software to control CPU Performance States.
