BIOS.SysProfileSettings.SysProfile (Read or Write)
Description
Allows optimizing the system for a specific profile, which presets multiple sub-options, or customizing the
individual sub-options. When set to a mode other than Custom, BIOS will set each option accordingly.
When set to Custom, you can change setting of each sub-option. Performance Per Watt (DAPC)
represents an excellent mix of performance balanced with power consumption reduction. Dell Active
Power Control (or DAPC) relies on a BIOS-centric power control mechanism which offers excellent power
efficiency advantages with minimal performance impact in most environments, and is the CPU Power
Management choice for this overall System Profile. Performance-per-watt (OS), otherwise known as 'OS
Control', is similar to the DAPC profile for all sub-options except for the CPU Power Management. The
power management scheme used for this profile is called 'OS DBPM', which allows the Operating System
to manipulate processor frequencies for higher power efficiency. However, the effectiveness of this
profile for reducing overall system power consumption is based on how well the Operating System is able
to effectively control hardware resources, so the impacts are mixed across all supported Operating
Systems Performance profile provides potentially increased performance by maximizing processor
frequency and disabling certain power saving features such as C-states. Although not optimal for all
environments, this is an excellent starting point for performance optimization baseline comparisons.
Dense Configuration enhances reliability features and reduces power consumption at the cost of
considerable performance. This profile is targeted for operating environments where enhanced reliability is
desired and temperatures may exceed the thresholds encountered in less densely-packed data centers.
When set to Dense Configuration mode, Memory Performance is set one speed lower than the Maximum
Frequency to improve reliability. Under Custom mode when C states are enabled, Monitor/Mwait must
also be enabled.
Value-class systems do not support DAPC option.
