9.2.1 Power Management Modes

The R210 II uses operating system-based power management.
9.2.1.1 Power Saving BIOS Setting (OS Control)
Intel processors support Demand Based Switching (DBS) which enables the processor to dynamically
change its operating frequency in response to workload changes. The industry standard
implementation of this power management feature is in the Operating System (OS). The OS monitors
process and thread level utilization of the processor and uses processor controls to change the
processor's operating frequency. For heavy workloads, the OS runs the processor at higher
frequencies for additional performance. Lighter workloads do not need high performance, thus the
OS runs the processor at lower frequencies.
