Performance

Table 1. PerformancePerformance
Attribute Name Description
AdaptiveCStates Adaptive C-States allow the system to dynamically detect high usage of a discrete graphics and adjust system parameters for higher performance during that time period. This feature requires an AC adapter due to higher energy consumption and dynamically it is not possible to activate higher performance without an appropriate AC adapter. Other settings that conserve power may block the utilization of this feature. The following are the possible values:
  • Enabled
  • Disabled
AdjCachePrefetch Enables or disables the AdjacentCacheLinePrefetch feature. The following are the possible values:
  • Enabled—CPU fetches the adjacent cache line in the other half of the sector.
  • Disabled—CPU only fetches the cache line that contains the data currently required by the CPU.
CPUCore This field specifies whether the processor has one or more cores enabled. The performance of some applications improve with additional cores. The following are the possible values:
  • CoresAll—All cores are enabled.
  • Cores1—Only one core is enabled.

  • Cores3—Three cores are enabled.
  • Cores4—Four cores are enabled.

  • Cores20—Twenty cores are enabled.
  • Cores21—Twenty one cores are enabled.
  • Cores22—Twenty two cores are enabled.
  • Cores23—Twenty three cores are enabled.
  • Cores24—Twenty four cores are enabled.
  • Cores25—Twenty five cores are enabled.
  • Cores26—Twenty six cores are enabled.
  • Cores27—Twenty seven cores are enabled.
  • Cores28—Twenty eight cores are enabled.
CpuSnoopMode Configures the CPU snoop mode. The following are the possible values:
  • Early—Enables early snoop mode. Use this mode for latency-sensitive applications that do not require high remote bandwidth.
  • Home—Enables home snoop mode. Use this mode for applications that require high memory bandwidth.
  • ClusterOnDie—Enables cluster on die mode. Dell recommends this mode for NUMA-optimized applications to achieve lowest local memory latency, and highest local memory bandwidth.
  • OppSnoop—Enables opportunistic snoop mode. Directory with Opportunistic Snoop Broadcast (OSB) offers a good balance of latency and bandwidth.
  • NoSnoop—Enables no snoop mode.
CStatesCtrl Enables or disables additional processor sleep states. The operating system may optionally use these states for additional power savings when idle. The following are the possible values:
  • Enabled
  • Disabled
DRmt The Dell Reliable Memory Technology (RMT) feature identifies and filters out defective regions of the memory modules before they are consumed by the BIOS or OS. When enabled, the system automatically identifies errors, record their locations, and exclude bad location on reboot. The following are the possible values:
  • Enabled
  • Disabled
DynTunML Enables operating system capability to enhance dynamic power tuning capabilities based on detected workloads. Protections for exposure: The –Admin password restricts editing the command –Removed in case when you are using command line interface. The following are the possible values:
  • Enabled
  • Disabled
EnableMultiCoreSupport Enables or disables multiple CPU cores. The following are the possible values:
  • Enabled—The operating system is allowed to access additional cores present on a single CPU package.
  • Disabled—The operating system is prevented to access additional cores present on a single CPU package.
HwPrefetcher Enables or disables the CPU's hardware prefetcher. If enabled, the processor's Hardware Prefetcher will automatically prefetch data and code for the processor. The following are the possible values:
  • Enabled
  • Disabled
IntelRapidStart Enables or disables the Intel Rapid Start feature. The Intel Rapid Start feature reduces power consumption by putting the system into a low-power state during sleep mode after the specified amount of time (minutes). The resume time may be slightly more than resuming the system from a sleep mode, but less than resuming from a hibernate mode. Intel Rapid Start Technology is automatically be disabled due to configuration changes, such as:
  • Hard disk configuration or partition changes
  • Memory capacity over 8GB is installed.
  • System or HDD password is enabled.
  • A Dell Encryption Accelerator card is installed.
  • The BlockSleep setting is enabled.
IntelRapidStartInstantOnDisplay Enables or disables displaying the system logo from cache during system resume using Intel Rapid Start Technology. The following are the possible values:
  • Enabled—Displays the system logo from cache during system resume using Intel Rapid Start Technology.
  • Disabled—Does not display the system logo from cache during system resume using Intel Rapid Start Technology.
IntelSpdSelTech Intel Speed Select Technology allows you to choose up to two additional base frequency conditions. Cfg 1: TDP Level 3 Cfg 2: TDP Level 4. The following are the possible values:
  • Configuration 1
  • Configuration 2
IrstTimer Sets the Intel Rapid Start Timer. The value can be specified in minutes ranging from 0 to 999. Specify the Rapid Start timer value as 0 to put the system into a low-power state immediately after the system transition to a sleep mode. The following are the possible values: Integer ranging from 0 to 999.
LimitCpuidValue Restricts the maximum CPUID functions supported by the processor. Some operating system does not complete the installation when more than three CPUID functions are supported. The following are the possible values:
  • Enabled
  • Disabled
LogicProc Enables or disables HyperThreading in the processor. The following are the possible values:
  • Enabled
  • Disabled
