ETX®-CD / Features and Interfaces
4.7 Speedstep Technology
The Intel® processors 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.
