1. Enhanced Intel SpeedStep® technology enables real-time dynamic switching of the voltage and frequency between two performance modes based on processor demand. This occurs by switching the system bus ratios, core operating voltage, and core processor speeds without resetting the system. The Mobile Pentium® III Processor – M is available at the following frequencies and voltages (Maximum Performance mode/Battery Optimized mode): 1133/733 MHz, 1066/733 MHz, 1000/733 MHz, 933/733 MHz and 866/667 MHz at 1.40V/1.15V.
