System Profile
Sets the System Profile to Performance Optimized, Power Optimized (DAPC), Power Optimized (OS), Dense Configuration Optimized, or Custom mode. When set to a mode other than Custom, BIOS sets each option accordingly. When set to Custom, you can change setting of each option.
CPU Power Management
Sets the CPU Power Management to Maximum Performance, OS DBPM, or System DBPM (DAAPC) mode.
Memory Frequency
Sets the speed of system memory frequency as Maximum Performance, 2133MHz, 1866MHz, 1600Mhz, 1333MHz, 1067MHz, 800MHz, or Maximum Reliability.
Turbo Boost
When set to Enabled, the processor can operate in Turbo Boost Mode.
Number of Turbo Boost Enabled Cores for Processor N
Sets the number of Turbo Boost enabled cores for the processor. By default, the maximum number of cores per processor is enabled.
C1E
Enabled | The processor is allowed to switch to minimum performance state when idle. |
---|---|
Disabled | The system disables the turbo mode capability of the processor. |
C States
When set to Enabled, the processor can operate in all available Power States.
Monitor/Mwait
Specifies if the Monitor/Mwait instructions are enabled. Monitor/Mwait can be disabled only when C State is disabled in custom mode. When C State is enabled in Custom mode, changing the Monitor/Mwait settings does not affect the system power/performance.
Workload Profile
Allows you to optimize the performance based on the workload.
Power Saver
Enables or Disables the Power Saver DAPC algorithm.
Memory Patrol Scrub
Sets the Memory Patrol Scrub frequency as Standard Mode, or Extended Mode.
Memory Refresh Rate
Sets the Memory Refresh Rate as 1x or 2x.
Memory Operating Voltage
Sets the DIMM voltage selection.
Auto (default) | The system automatically sets the system Voltage to the optimal setting based on the DIMM capability and the installed DIMM population. |
---|---|
1.5 V | Enables setting the system DIMM voltage to a higher (1.5 V) setting if the DIMMs support multiple voltages and have been Auto set to a lower voltage. |
Collaborative CPU Performance Control
When set to Enabled, the CPU power management controls the OS DBPM and the System DBPM (DAPC). This feature can be enabled only when CPU Power Management is set to System DBPM (DAPC) in Custom mode. Else, changing this setting does not affect the system power or performance.
Energy Efficient Turbo
Sets the Energy Efficient Turbo as enabled or disabled.
Energy Efficient Policy
Sets the Energy Efficient Policy as Performance, Balanced Performance, Balanced Energy, and Energy Efficient.
Uncore Frequency
Sets the Processor Uncore Frequency as Dynamic or Maximum.
