– Platform Controlled Type
Select this choice to determine how to balance between performance and power consumption.
Choosing Maximum Performance will disable power management functions and allow the most
aggressive use of turbo. Choosing Minimal Power will maximizes the use of power management
features for least power consumption and disable turbo.
Note: It is available only when System Settings → Power → Power/Performance Bias → Platform
Controlled is enabled.
– Workload Configuration
Select this choice to determine how to balance between I/O bandwidth and balanced workload.
Choosing I/O sensitive will get higher I/O bandwidth while expansion cards are used. Choosing
Balanced will allow enough frequency for workload while the microprocessor cores are idle.
– Operating Modes
Select this choice to view or change the operating profile (performance and power utilization). This
choice specify a preset operating mode to configure the server for maximum power savings, maximum
efficiency, and maximum performance.
– Choose Operating Mode
Select the operating mode based on your preference. Power savings and performance are also
highly dependent on hardware and software running on the system. When a present mode is
selected, the low-level settings are not changeable and will be grayed out.
– Memory Speed
Select the desired memory speed. Maximum performance mode maximizes performance. Balanced
mode offers a balance between performance and power. Minimal power mode maximizes power
savings.
– Memory Power Management
Select this choice to enable or disable power management on memory. If you choose Disabled, it
will provide maximum performance but minimum power savings. If you choose Automatic, it is
suitable for most applications.
– Proc Performance States
Select this choice to enable or disable processor performance states. Enabling processor
performance states (Intel Speedstep Technology) saves power by reducing speed and voltage as
the microprocessor utilized is reduced.
Note: Some operating systems must have the correct power profile selected to take advantage of
this feature.
– C1 Enhance Mode
Select this choice to enable or disable C1E (C1 Enhanced) state. Enabling C1E (C1 Enhanced) state
can save power by halting CPU cores that are idle.
Note: An operating system that supports C1E state must be installed to take advantage of this
feature. Changing this setting will be effective after the next system reboot.
– QPI Link Frequency
Select this choice to determine the desired microprocessor QPI link frequency. Maximum
performance mode maximizes performance. Balanced mode offers a balance between performance
and power. Minimal power maximizes power savings.
– Turbo Mode
