Power Regulator settings change.

Power Regulator modes
Choose from the following modes when you configure the Power Regulator settings:
• Dynamic Power Savings Mode—Automatically varies processor speed and power usage based on
processor utilization. This option allows the reduction of overall power consumption with little or no
impact to performance. It does not require OS support.
• Static Low Power Mode—Reduces processor speed and power usage. This option guarantees a
lower maximum power usage value for the system.
• Static High Performance Mode—Processors will run at maximum power and performance at all
times, regardless of the OS power management policy.
• OS Control Mode—Processors will run at maximum power and performance at all times, unless the
OS enables a power management policy.
