System Profile
|
Sets the system profile. Setting the
System Profile option to a mode other than
Performance Per Watt (DAPC), has the BIOS automatically set 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
Custom,
Performance,
Performance Per Watt (OS), and
Workstation Performnce.
NOTE: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. Other option includes
Maximum Performance,
OS DBPM.
|
Memory Frequency
|
Sets the speed of the system memory. You can select
Maximum Performance,
Maximum Reliability, or a specific speed. This option is set to
Maximum Performance by default.
|
Turbo Boost
|
Enables or disables the processor to operate in the turbo boost mode. This option is set to
Enabled by default.
|
Energy Efficient Turbo
|
Energy Efficient Turbo (EET) is a mode of operation where the processor core frequency is adjusted within the turbo range based on workload. This option is set to
Enabled by default.
|
C1E
|
Enables or disables the processor to switch to a minimum performance state when it is idle. This option is set to
Enabled by default.
|
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 (operating system controlled), or
Autonomous (if hardware controlled is supported), the processor operates in all available Power States to save power. The
Enabled and
Autonomous settings may increase memory latency and frequency jitter. This option is set to
Enabled by default.
|
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 to either 1x or 2x. 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
Energy Efficiency Policy option influences the optimization of the uncore frequency to either save power, or to optimize the performance.
|
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.
NOTE:This option can be disabled when System Profile is set to
Custom.
NOTE:When the C States option 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 and allows performance optimization that is based on the workload type. This option is set to
Not Configured by default.
|
CPU Interconnect Bus Link Power Management
|
Enables or disables the CPU Interconnect Bus Link Power Management. This option is set to
Enabled by default.
|
PCI ASPM L1 Link Power Management
|
Enables or disables the PCI
ASPM L1 Link Power Management. This option is set to
Enabled by default.
