Option
Description
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 (OS) by default. Other options include
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.
CPU Power Management
Sets the CPU power management. The options includes
Maximum Performance and
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.
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 Refresh Rate
Sets the memory refresh rate to either 1x or 2x. This option is set to
2x 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.
Maximum mode enables the maximum uncore frequency.
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. This setting is read-only and set to
Enabled when Optimized Power Mode is Enabled.
Read - Only unless System Profile is set to Custom.
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 C States is set to Enabled in the Custom mode, changing the Monitor/Mwait setting does not impact the system power or performance.
PCI ASPM L1 Link Power Management
