Dependency Not applicable BIOS.SysProfileSettings.ProcPwrPerf (Read or Write) Description Allows selection of CPU power management methodology. System DBPM (Demand-based Power Management) utilizes a BIOS-controlled dynamic frequency manipulation scheme to save power across a variety of utilization levels as part of the Dell Advanced Power Control (DAPC) capability. The power saving features of this option typically are greatest at mid-to-lower processor utilization levels. Maximum Performance is typically selected for performance-centric workloads where it is acceptable to consume additional power to achieve the highest possible performance for the computing environment. This mode drives processor frequency to the maximum across all cores (although idled cores can still be frequency reduced by C-state enforcement through BIOS or OS mechanisms if enabled). This mode also offers the lowest latency of the CPU Power Management Mode options, so is always preferred for latency-sensitive environments. OS DBPM is another performance-per-watt option that relies on the operating system to dynamically control individual core frequency. Both Windows and Linux can take advantage of this mode to reduce frequency of idled or underutilized cores in order to save power. Read-only unless System Profile is set to Custom. Has a dependency on the System Profile. Can only be set if the System Profile is set to Custom. Legal Values ● MaxPerf ● MinPwr ● SysDbpm ● OsDbpm ● HwpDbpm Default Value Not Applicable Write Privilege Server Control License Required iDRAC Express or iDRAC Enterprise Dependency Not applicable BIOS.SysProfileSettings.ProcTurboMode (Read or Write) Description Governs the Intel Turbo Boost Technology. This feature allows the processor cores to be automatically clocked up in frequency beyond the advertised processor speed. The amount of increased frequency (or 'turbo upside') one can expect from a Xeon processor depends on the processor model, thermal limitations of the operating environment, and in some cases power consumption. In general terms, the fewer cores being exercised with work the higher the potential turbo upside. The potential drawbacks for Turbo Boost are mainly centered on increased power consumption and possible frequency jitter than can affect a small minority of latency-sensitive environments. Read-only unless System Profile is set to Custom. Has a dependency on the System Profile. Can only be set if the System Profile is set to Custom. Is set to Enabled if the System Profile is set to Performance Per Watt (DAPC), Performance Per Watt (OS), Performance Per Watt (HWPM), or Performance. Is set to Disabled if the System Profile is set to Dense.
