Dual-Core Intel® Xeon® Processor 3000 Series Datasheet
The following are key features of Enhanced Intel SpeedStep
®
Technology:
• Multiple voltage/frequency operating points provide optimal performance at
reduced power consumption.
• Voltage/frequency selection is software controlled by writing to processor MSRs
(Model Specific Registers), thus eliminating chipset dependency.
— If the target frequency is higher than the current frequency, V
CC
is incremented
in steps (+12.5 mV) by placing a new value on the VID signals and the
processor shifts to the new frequency. Note that the top frequency for the
processor can not be exceeded.
— If the target frequency is lower than the current frequency, the processor shifts
to the new frequency and V
CC
is then decremented in steps (-12.5 mV) by
changing the target VID through the VID signals.
