Setting the Power Regulator modeSetting the Power Regulator mode
Use Power Regulator settings to help increase server efficiency and manage power consumption.
NOTE:NOTE:
Certain processors only support one power state and operate at their initialized frequency, regardless of the selected
power regulator mode.
PrerequisitePrerequisite
Workload Profile is set to Custom.
ProcedureProcedure
1. From the System Utilities screen, select System Configuration > BIOS/Platform Configuration (RBSU) > Power and Performance
Options > Power Regulator.
2. Select a setting.
Dynamic Power Savings Mode —Automatically varies processor speed and power usage based on processor utilization. This
mode uses an ROM-based algorithm to monitor processor activity. It can reduce overall power consumption with little or no
impact to performance, and does not require OS support.
Static Low Power Mode —Reduces processor speed and power usage. Guarantees a lower maximum power usage for the system.
This mode is useful in environments where power availability is constrained and it is critical to lower the maximum power use of
the system.
Static High Performance Mode—Processors run in the maximum power and performance state, regardless of the OS power
management policy. This mode is useful in environments where performance is critical and power consumption is less
important.
OS Control Mode —Processors run in their maximum power and performance state at all times, unless the OS enables a power
management policy.
3. Save your setting.
