Option Description
Adjacent Cache Optimizes the system for applications that need high utilization of sequential memory access. This option
Line Prefetch is set to Enabled by default. You can disable this option for applications that need high utilization of
random memory access.
Hardware Enables or disables the hardware prefetcher. This option is set to Enabled by default.
Prefetcher
Software Enables or disables the software prefetcher. This option is set to Enabled by default.
Prefetcher
DCU Streamer Enables or disables the Data Cache Unit (DCU) streamer prefetcher. This option is set to Enabled by
Prefetcher default.
DCU IP Enables or disables the Data Cache Unit (DCU) IP prefetcher. This option is set to Enabled by default.
Prefetcher
Sub NUMA Sub NUMA Clustering (SNC) is a feature for breaking up the LLC into disjoint clusters based on address
Cluster range, with each cluster bound to a subset of the memory controllers in the system. It improves average
latency to the LLC. Enables or disables the Sub NUMA Cluster. This option is set to Disabled by default.
UPI Prefetch Enables you to get the memory that is read started early on DDR bus. The Ultra Path Interconnect (UPI)
Rx path will spawn the speculative memory that is read to Integrated Memory Controller (iMC) directly.
This option is set to Enabled by default.
LLC Prefetch Enables or disables the LLC Prefetch on all threads. This option is set to Disabled by default.
Dead Line LLC Enables or disables the Dead Line LLC Alloc. This option is set to Enabled by default. You can enable this
Alloc option to enter the dead lines in LLC or disable the option to not enter the dead lines in LLC.
Directory AtoS 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.
Logical Enables you to improve the energy efficiency of a system. It uses the operating system core parking
Processor Idling 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.
Configurable TDP Enables you to configure the TDP level. The available options are Nominal, Level 1, and Level 2. This
option is set to Nominal by default.
SST- Enables you to reconfigure the processor using Speed Select Technology.
