Option Description
However, if power saving considerations outweigh performance, you might want to reduce the frequency of the
CPU communication links. If you do this, you should localize memory and I/O accesses to the nearest NUMA node
to minimize the impact to system performance.
Virtualization Enables or disables the virtualization technology for the processor. This option is set to Enabled by default.
Technology
Adjacent Cache Optimizes the system for applications that need high utilization of sequential memory access. This option is set to
Line Prefetch 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
DCU Streamer Enables or disables the Data Cache Unit (DCU) streamer prefetcher. This option is set to Enabled by default.
Prefetcher
DCU IP Prefetcher Enables or disables the Data Cache Unit (DCU) IP prefetcher. This option is set to Enabled by default.
Sub NUMA Cluster Enables or disables the Sub NUMA Cluster. This option is set to Disabled by default.
Logical Processor Enables you to improve the energy efficiency of a system. It uses the operating system core parking algorithm and
Idling 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.
X2APIC Mode Enables or disables the X2APIC mode. This option is set to Disabled by default.
Dell Controlled Controls the turbo engagement. Enable this option only when System Profile is set to Disabled.
Turbo
Number of Cores Controls the number of enabled cores in each processor. This option is set to All by default.
