System profile screen settings
The System Profile Settings screen details are explained as follows:
Table 20. System profile settings
Menu Item | 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. By default, the System Profile |
| option is set to Performance Per Watt Optimized (DAPC). DAPC is Dell Active |
| Power Controller. |
| NOTE: The following parameters are available only when the System Profile is |
| set to Custom. |
| • CPU Power Management: Sets the CPU power management. By default, the |
| CPU Power Management option is set to System DBPM (DAPC). DBPM is |
| |
| • Memory Frequency: Sets the speed of the system memory. You can select |
| Maximum Performance, Maximum Reliability, or a specific speed. |
| • Turbo Boost: Enables or disables the processor to operate in turbo boost |
| mode. By default, the Turbo Boost option is set to Enabled. |
| • Energy Efficient Turbo: Enables or disables the Energy 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. |
| • C1E: Enables or disables the processor to switch to a minimum performance |
| state when it is idle. By default, the C1E option is set to Enabled. |
| • C States: Enables or disables the processor to operate in all available power |
| states. By default, the C States option is set to Enabled. |
| • Collaborative CPU Performance Control: Enables or disables the CPU power |
| management. When set to Enabled, the CPU power management is controlled |
| by the OS DBPM and the System DBPM (DAPC). By default, the option is set to |
| Disabled. |
| • Memory Patrol Scrub: Sets the memory patrol scrub frequency. By default, the |
| Memory Patrol Scrub option is set to Standard. |
| • Memory Refresh Rate: Sets the memory refresh rate to either 1x or 2x. By |
| default, the Memory Refresh Rate option is set to 1x. |
| • Uncore Frequency: Selects the Processor Uncore Frequency. |
| Dynamic mode allows the processor to optimize power resources across the |
| cores and uncore 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. |
| • Energy Efficient Policy: Enables you to selects the Energy Efficient Policy. |
| The CPU uses the setting to manipulate the internal behavior of the processor |
| and determines whether to target higher performance or better power savings. |
| • Number of Turbo Boot Enabled Cores for Processor 1: |
| NOTE: If there are two processors installed in the system, you see an entry |
| for Number of Turbo Boost Enabled Cores for Processor 2. |
Controls the number of turbo boost enabled cores for processor 1. By default, the maximum number of cores is enabled.
•Monitor/Mwait: Enables the Monitor/Mwait instructions in the processor. By default, the Monitor/Mwait option is set to Enabled for all system profiles, except Custom.
