Power

This menu allows you to configure power scheme options.

Table 1. Power

Item	Options	Description
Power/Performance Bias	Platform Controlled (Default) OS Controlled	Power/Performance Bias determines how the power management of the processor is controlled. [Platform Controlled]: The system controls the setting. [OS Controlled]: The operating system controls the setting. Not all operating systems support this feature. When a preset mode is selected, the low-level settings are not changeable and will be grayed out. To change the settings, choose System Settings > Operating Modes > Choose Operating Mode > Custom Mode.
Platform Controlled Type	Maximum Performance Efficiency - Favor Performance (Default) Efficiency - Favor Power Minimal Power	[Maximum Performance] allows the most aggressive use of turbo and power management functions are disabled, thereby increasing power consumption. [Minimal Power] disables turbo and maximizes the use of power management features. When a preset mode is selected, the low-level settings are not changeable and will be grayed out. To change the settings, choose System Settings > Operating Modes > Choose Operating Mode > Custom Mode.
Workload Configuration	Balanced (Default) I/O sensitive	[I/O sensitive] is recommended for expansion cards that require the high bandwidth I/O when the processor cores are idle to allow enough frequency for the workload.
ACPI Fixed Power Button	Enabled (Default) Disabled	Enables or disables ACPI Fixed Power Button. When [Disabled] is selected, pressing the power button on front of the system does not execute the power button policy in operating system, such as shutdown and turn off monitor. In addition, the "Shut down OS and ..." options under the iMM Server Power Actions feature will be disabled.
PCIe Power Brake	Reactive Proactive (Default) Disabled	PCIe Power Brake quickly reduces the power consumption and performance of high-power PCIe devices. Performances of low-power PCIe devices are not impacted by this setting. A high-power PCIe device refers to the one with a rated power of 75 W TDP or greater. Note This feature is platform dependent.
ASPM	Auto (Default) Disabled	[Auto] enables ASPM on PCIe endpoint adapters that support it. [Disabled] disables ASPM for all PCIe endpoints. Note This feature is platform dependent.
