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 Demand- |
| Based Power Management. |
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. |

| 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. |
