Serial Communication

The Serial Communication screen details are explained as follows:

Option
Description
Serial Communication
Selects serial communication devices (Serial Device 1 and Serial Device 2) in BIOS. BIOS console redirection can also be enabled and the port address can be specified. This option is set to Auto by default.
Serial Port Address
Enables you to set the port address for serial devices. This option is set to Serial Device 1=COM2, Serial Device 2=COM1 by default.
* 
NOTE: You can use only Serial Device 2 for the Serial Over LAN (SOL) feature. To use console redirection by SOL, configure the same port address for console redirection and the serial device.
* 
NOTE: Every time the system boots, the BIOS syncs the serial MUX setting saved in iDRAC. The serial MUX setting can independently be changed in iDRAC. Loading the BIOS default settings from within the BIOS setup utility may not always revert the serial MUX setting to the default setting of Serial Device 1.
External Serial Connector
Enables you to associate the External Serial Connector to Serial Device 1, Serial Device 2, or the Remote Access Device by using this option.
* 
NOTE: Only Serial Device 2 can be used for Serial Over LAN (SOL). To use console redirection by SOL, configure the same port address for console redirection and the serial device.
* 
NOTE: Every time the system boots, the BIOS syncs the serial MUX setting saved in iDRAC. The serial MUX setting can independently be changed in iDRAC. Loading the BIOS default settings from within the BIOS setup utility may not always revert this setting to the default setting of Serial Device 1.
Failsafe Baud Rate
Specifies the failsafe baud rate for console redirection. The BIOS attempts to determine the baud rate automatically. This failsafe baud rate is used only if the attempt fails, and the value must not be changed. This option is set to 115200 by default.
Remote Terminal Type
Sets the remote console terminal type. This option is set to VT 100/VT 220 by default.
Redirection After Boot
Enables or disables the BIOS console redirection when the operating system is loaded. This option is set to Enabled by default.

System Profile Settings details

The System Profile Settings screen details are explained as follows:

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 Optimized (DAPC) by default. DAPC is Dell Active Power Controller.
* 
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. This option is set to System DBPM (DAPC) by default. 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 the turbo boost mode. This option is set to Enabled by default.
Energy Efficient Turbo
Enables or disables the Energy Efficient Turbo option.
Energy Efficient Turbo (EET) is a mode of operation where a processor’s core frequency is adjusted to be within the turbo range based on workload.
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. This option is set to Enabled by default.
Collaborative CPU Performance Control
Enables or disables the CPU power management option. When set to Enabled, the CPU power management is controlled by the OS DBPM and the System DBPM (DAPC). This option is set to Disabled by default.
Memory Patrol Scrub
Sets the memory patrol scrub frequency. This option is set to Standard by default.
Memory Refresh Rate
Sets the memory refresh rate to either 1x or 2x. This option is set to 1x by default.
Uncore Frequency
Enables you to select the Processor Uncore Frequency option.
Dynamic mode enables 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 option.
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.
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. The maximum number of cores is enabled 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.
