Description

Power/Performance Bias

  • Platform Controlled

  • OS Controlled

Power/Performance bias determines how aggressively the CPU will be power managed and placed into turbo. With [Platform Controlled], the system controls the setting. Selecting [OS Controlled] allows the operating system to control it. Not all OSes support this feature. When a preset mode is selected, the low-level settings are not changeable and will be grayed out. If user would like to change the settings, choose [Custom Mode] in “Operating Mode” located under “System Setting” submenu.

Platform Controlled is the default setting.

Platform Controlled Type

  • Maximum Performance

  • Efficiency - Favor Performance

  • 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. If user would like to change the settings, please choose [Custom Mode] in “Operating Mode” located under “System Setting” submenu.

Efficiency - Favor Performance is the default setting.

Workload Configuration

  • Balanced

  • I/O sensitive

I/O sensitive should be used with expansion cards that require high I/O bandwidth when the CPU cores are idle to allow enough frequency for the workload.

Balanced is the default setting.

ACPI Fixed Power Button

  • Enable

  • Disable

Enable/Disable ACPI Fixed Power Button. When setting as disabled, physically pressing the power button on front of the system won't execute the Operating System's Power Button Policy such as shutdown, turn off monitor, etc. Also, when disabled the 'Shut down OS and ..." options under the iMM Server Power Actions feature will be disabled.

Enable is the default setting.

Zero Output

  • Disable

  • Advance Mode

When zero output is enabled and multiple power supplies are installed in the server, some of the PSUs will be automatically placed into a low power state under light load conditions. This helps to save power.

Disable is the default setting.
