Advanced Power Management Configuration

Advanced Power Management Configuration

This topic describes how to configure the power supply for a CPU on the Advanced Power Management Configuration screen.

You can configure the power supply for a CPU on the Advanced Power Management Configuration screen. Table 5-14 describes the parameters on this screen. Figure 5-17 shows the Advanced Power Management Configuration screen.

Figure 5-17 Advanced Power Management Configuration screen

Table 5-14 Parameters on the Advanced Power Management Configuration screen

Parameter

Description

Default Value

Power Policy Select

Power supply policy. The options are as follows:

  • Efficiency: indicates the low-performance low-consumption mode, in which efficiency has a higher priority and the power consumption can be reduced.

    If this option is selected, the following parameters will be automatically set as follows:

    • EIST: Enable
    • Turbo Mode: Enable
    • CPU C3 report: Enable
    • CPU C6 report: Enable
    • Enhanced Halt State (C1E): Enable
    • ACPI T-States: Enable
    • Monitor/Mwait: Enable
  • Performance: indicates the high-performance high-consumption mode, in which performance has a higher priority.

    If this option is selected, the following parameters will be automatically set as follows:

    • EIST: Enable
    • Turbo Mode: Enable
    • CPU C3 report: Disable
    • CPU C6 report: Disable
    • Enhanced Halt State (C1E): Disable
    • ACPI T-States: Enable
    • Monitor/Mwait: Disable
  • Custom: indicates the user-defined policy that considers performance, delay, and energy consumption. The standard CPU operating frequency is recommended.

    If this option is selected, the following parameters will be automatically set as follows:

    • CPU Power Save Mode: Disable
    • EIST: Disable
    • Turbo Mode: Disable
    • CPU C3 report: Disable
    • CPU C6 report: Disable
    • Enhanced Halt State (C1E): Disable
    • ACPI T-States: Enable
    • Monitor/Mwait: Disable

Custom

CPU Power Save Mode

Indicates whether to enable the energy saving function for processors. This function automatically adjusts the speed and power consumption of processors based on the processor usage. The overall power consumption can be reduced with little or no impact on performance. The function can be enabled in the BIOS even when the OS does not support the function. The options are as follows:

  • Enable
  • Disable

Disable

Memory Turbo (not for the E9000)

Indicates whether to enable the Turbo Boost function for the memory. The options are as follows:

  • Enable
  • Disable

Disable

CPU P State Control

CPU P-state control menu, which specifies whether to enable the Turbo mode and Enhanced Intel SpeedStep Technology (EIST).

-

CPU C State Control

CPU C-state control menu, which controls the power consumption of CPUs in idle state.

-

CPU T State Control

CPU T-state control menu, which is used to adjust the CPU frequency.

-

Table 5-15 describes the parameters on the Haswell CPU P State Control screen. Figure 5-18 shows the CPU P State Control screen.

NOTE:

If the EIST and Turbo Mode parameters are unavailable, set the default value of the Power Policy Select parameter on the Advanced Power Management Configuration screen to Custom.

Parameter

Description

Default Value

EIST (P-states)

Indicates the intelligent frequency control. In the Energy Efficient Turbo (EET) mode, the core frequency of the processor can be adjusted within the workload turbo range. The options are as follows:

  • Enable
  • Disable

Disable

Turbo Mode

Indicates the dynamic acceleration control. If the processor has an available power supply and the temperature is normal, the Turbo Boost technology enables its frequency higher than the rated power. Disabling this option reduces the power consumption and the maximum system performance in certain workloads. The options are as follows:

  • Enable
  • Disable

If the processor does not support the Turbo mode, the value of Turbo Mode is displayed as Disable and is not changeable.

Disable

Table 5-16 describes the parameters on the CPU C State Control screen. Figure 5-19 shows the screen.

Figure 5-19 CPU C State Control screen

Table 5-16 Parameters on the CPU C State Control screen

Parameter

Description

Default Value

Package C State limit

C state limit. This parameter allows you to set the processor to the idle state (C-state) with the least power consumption. The state of the processor automatically changes to the package C-state based on the core C-state, and the state of cores changes. The power consumption by the package in the idle state reduces as the package C-state level increases (In the package C6 (Retention) state, the power consumption is minimum). The options are as follows:

  • C0/C1 state
  • C2 state
  • C6 (non Retention) state
  • C6 (Retention) state

C0/C1 state

CPU C3 report

Indicates whether to enable the function for reporting the C3 state to the operating system (OS). The options are as follows:

  • Enable
  • Disable

Disable

CPU C6 report

Indicates whether to enable the function for reporting the C6 state to the OS. The options are as follows:

  • Enable
  • Disable

Disable

Enhanced Halt State (C1E)

Indicates whether to enable the C1E function. After this function is enabled, the OS can adjust the C-state. If this option is enabled, the processor is allowed to change to the lowest frequency in the idle state. The options are as follows:

  • Enable
  • Disable

Disable

Table 5-17 describes parameters on the CPU T State Control screen. Figure 5-20 shows the screen.

Description

Default Value

ACPI T-States

Indicates whether to enable the function for adjusting the CPU frequency. The options are as follows:

  • Enable
  • Disable

Disable
