System Profile
|
Sets the system profile. If you set the System Profile option to a mode other than
Performance Per Watt (DAPC), 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),
Workstation Performance and
Custom.
NOTE:All the parameters on the system profile setting screen are available only when the
System Profile option is set to
Custom.
|
Optimized Power Mode
|
When set to
Enabled, processor is tuned for lower power consumption. Also sets C1E to
Enabled, sets CPU Power Management to System DBPM mode, sets Energy-Efficient Policy to Performance, sets Uncore Frequency to Dynamic, and sets Dynamic Load Line Switch to
Enabled.
|
CPU Power Management
|
Sets the CPU power management. This option is set to
System DBPM (DAPC) by default. Other options include
Maximum Performance, OS DBPM.
|
Memory Frequency
|
Sets the speed of the system memory. 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.
|
Enery Efficient Turbo
|
Energy Efficient Turbo (EET) is a mode of operation where a processor's 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 (OS 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. 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, this option is set to
1x by default.
|
Uncore Frequency
|
Enables you to select the
Uncore Frequency option.
Dynamic 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.
|
Dynamic Load Line Switch
|
Dynamic Load Line Switch control. Dynamic Load Line (DLL) is a Power Management feature, which dynamically switches to the performance mode during periods of high CPU utilization. Read-only unless System Profile is set to
Custom.
|
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 only if the C States option in the Custom mode is set to disabled.
NOTE: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. Below is the list of available profiles:
- Not Configured
- HPC Profile
- Low Latency Optimized Profile
- Virtualization Optimized Performance Profile
- Virtualization Optimized Performance Per Watt Profile
- Database Optimized Performance Profile
- Database Optimized Performance Per Watt Profile
- SDS Optimized Performance Profile
- SDS Optimized Performance Per Watt Profile
- Telco Optimized Profile
- NFVI FP Optimized Turbo Profile
- NFVI FP Energy-Balance Turbo Profile
|
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.
|
Workload Configuration
|
This field controls the Energy Performance Bias settings to allow BIOS to choose a configuration that improves performance on certain workload. The two options for selection are
Balance and
IO Sensitive. This option is set to
Balance by default.
