System Profile
|
Sets the system profile. If you set the System Profile option to a mode other than
Custom, the BIOS automatically sets the rest of the options. You can only change the rest of the options if the mode is set to
Custom. This option is set to
Performance Per Watt (DAPC) by default. Other options include
Performance,
Performance Per Watt (OS) and
Custom. This option is set to
Performance Per Watt (OS) by default. Other options include
Performance and
Custom.
All the parameters on the system profile setting screen are available only when the
System Profile option is set to
Custom.
|
CPU Power Management
|
Sets the CPU power management. This option is set to
System DBPM (DAPC) by default.
|
Memory Frequency
|
Sets the speed of the system memory. This option is set to
Maximum Performance by default.
|
Turbo Boost
|
Enables (default) or disables the processor to operate in the turbo boost mode.
|
C1E
|
Enables (default) or disables the processor to switch to a minimum performance state when it is idle.
|
C States
|
Enables or disables the processor to operate in all available power states. C States allow the processor to enter lower power states when idle. When set to
Enabled (default), which is operating system controlled, or when set to
Autonomous, if hardware controlled is supported, the processor can operate in all available Power States to save power, but may increase memory latency and frequency jitter.
|
Memory Patrol Scrub
|
Sets the memory patrol scrub mode. This option is set to
Standard by default.
|
Memory Refresh Rate
|
Sets the memory refresh rate, this option is set to
1x by default.
|
Uncore Frequency
|
Enables you to select the
Uncore Frequency option.
Dynamic mode enables the processor to optimize power resources across cores and uncores during runtime. The optimization of the uncore frequency to either save power or optimize performance is influenced by the setting of the
Energy Efficiency Policy option.
|
Energy Efficient Policy
|
Enables you to select the
Energy Efficient Policy option. The CPU uses the setting to manipulate the internal behavior of the processor and determines whether to target higher performance or better power savings. This option is set to
Balanced Performance by default.
|
Monitor/Mwait
|
Enables the Monitor/Mwait instructions in the processor. This option is set to
Enabled for all system profiles, except
Custom by default.
This option can be disabled only if the C States option in the Custom mode is set to disabled.
When C States is set to Enabled in the Custom mode, changing the Monitor/Mwait setting does not impact the system power or performance.
|
Workload Profile
|
This option allows the user to specify the targeted workload of a server. It allows optimization of performance based on the workload type. This option is set to
Not Configured by default.
|
CPU Interconnect Bus Link Power Management
|
Enables (default) or disables the CPU Interconnect Bus Link Power Management.
|
PCI ASPM L1 Link Power Management
|
Enables (default) or disables the PCI
ASPM L1 Link Power Management.
