Table 5. Processor Settings details (continued) Option Hardware Prefetcher DCU Streamer Prefetcher DCU IP Prefetcher Sub NUMA Cluster MADT Core Enumeration UPI Prefetch XPT Prefetch LLC Prefetch Dead Line LLC Alloc Directory AtoS Logical Processor Idling AVX P1 Dynamic SST-Performance Profile SST-Performance Profile Intel SST-BF Description Enables or disables the hardware prefetcher. This option is set to Enabled by default. Enables or disables the Data Cache Unit (DCU) streamer prefetcher. This option is set to Enabled by default. Enables or disables the Data Cache Unit (DCU) IP prefetcher. This option is set to Enabled by default. Enables or disables the Sub NUMA Cluster. This option is set to Disabled by default. Specifies the MADT Core Enumeration. This option is set to default in Round Robin. Enables you to get the memory read started early on DDR bus. The Ultra Path Interconnect (UPI) Rx path will spawn the speculative memory read to Integrated Memory Controller (iMC) directly. This option is set to Enabled by default. This option is set to Enabled by default. Enables or disables the LLC Prefetch on all threads. This option is set to Enabled by default. Enables or disables the Dead Line LLC Alloc. This option is set to Enabled by default. You can enable this option to enter the dead lines in LLC or disable the option to not enter the dead lines in LLC. Enables or disables the Directory AtoS. AtoS optimization reduces remote read latencies for repeat read accesses without intervening writes. This option is set to Disabled by default. Enables you to improve the energy efficiency of a system. It uses the operating system core parking algorithm and parks some of the logical processors in the system, which in turn allows the corresponding processor cores to transition into a lower power idle state. This option can only be enabled if the operating system supports it. It is set to Disabled by default. NOTE: This feature is not supported if CPU Power Management is set to Maximum Performance. Enables you to reconfigure the processor Thermal Design Power (TDP) levels during POST based on the power and thermal delivery capabilities of the system. TDP verifies the maximum heat the cooling system is needed to dissipate. This option is set to Normal by default. NOTE: This option is only available on certain stock keeping units (SKUs) of the processors. Enables you to reconfigure the processor using Dynamic or Static Speed Select Technology. This option is set to Disabled by default. Enables you to reconfigure the processor using Speed Select Technology. Enables Intel SST-BF. This option is displayed if Performance Per Watt (operating system) or Custom (when OSPM is enabled) system profiles are selected. This option is set to Disabled by default. 8 Pre-operating system management applications
