Processor Settings

Use this window to control the processor settings.

NOTE: The help page may include information about features and values that are not supported on your system. Server Administrator displays only the features and values that are supported on your system.

User Privileges

Table 1. User Privileges
Selection View Manage
Processor Settings Administrator, Elevated Administrator (Linux only) Administrator, Elevated Administrator (Linux only)
NOTE: For more details on user privilege levels, see Privilege levels in the Server Administrator GUI.

Logical Processor

Each processor core supports up to two logical processors.

Enabled (default) The BIOS reports all logical processors.
Disabled The BIOS only reports one logical processor per core.

QPI Speed

Controls QuickPath Interconnect data rate settings.

Alternate RTID (Requestor Transaction ID) setting

Enabled Allocates more RTIDs to the remote socket increasing cache performance between the sockets.
Disabled (default) Normal mode for NUMA.

Virtualization Technology

When enabled, the additional hardware capabilities provided by Virtualization Technology are available for use.

NOTE: Changing this option will result in a system power down of approximately 3 to 5 seconds after exiting the System Setup program.

Adjacent Cache Line Prefetch

When enabled (default), the system is optimized for applications that require high utilization of sequential memory access. Disable this option for applications that require high utilization of random memory access.

Hardware Prefetcher

Enables or disables the hardware prefetcher. This setting can affect performance, depending on the application running on the server and memory bandwidth utilization.

Software Prefetcher

Enables or disables the software prefetcher. When set to Enabled, the processor can prefetch extra cache lines for every memory request. This setting can affect performance, depending on the application running on the server and memory bandwidth utilization.

DCU Streamer Prefetcher

Enables (default) or disables DCU Streamer Prefetcher. This setting can affect performance, depending on the application running on the server. Recommended for High Performance Computing applications.

DCU IP Prefetcher

Enables (default) or disables DCU IP Prefetcher. This setting can affect performance, depending on the application running on the server. Recommended for High Performance Computing applications.

Sub NUMA Cluster

Sub NUMA Clustering (SNC) is a feature breaking up the LLC into disjoint clusters based on address range, with each cluster bound to a subset of the memory controllers in the system. It improves average latency to the LLC.

UPI Prefetch

UPI Prefetch is a mechanism to get the memory read started early on DDR bus, the UPI Rx path spawns a MemSpecRd to iMC directly.

Execute Disable

Specifies whether Execute Disable Memory Protection Technology is enabled.

Enabled (default) The Execute Disable Memory Protection Technology is enabled.
Disabled The Execute Disable Memory Protection Technology is disabled.

Logical Processor Idling

Enables or disables the operating system capability to group logical processors in the idling state in order to reduce power consumption.

x2APIC Mode

Enables or disables x2APIC mode. Compared to the traditional xAPIC architecture, x2APIC extends processor addressability and enhances interrupt delivery performance. Virtualization Technology is set to Enabled to allow enabling and disabling of x2APIC mode. The x2APIC mode is forced to Disabled when Virtualization Technology is disabled.

Number of Cores per Processor

Controls the number of enabled cores in each processor. By default, the maximum number of cores per processor is enabled.

Processor 64-bit Support

Specifies whether the installed processor(s) support 64-bit extensions.

Processor Core Speed

Displays the clock speed of the processor.

Family-Model-Stepping

Displays the processor family, model, and stepping values.

Brand

Displays the brand text provided by the processor manufacturer.

Level 2 Cache

Displays the amount of memory in the corresponding processor cache.

Level 3 Cache

Displays the amount of memory in the corresponding processor cache.

Number of Cores

Displays the number of cores in the processor package.

Dell Controlled Turbo

Displays the state of the Turbo mode. Enable this option only when System Profile is set to Performance. The default option is Disabled.

Dell AVX Scaling Technology

Displays the state of the AVX scaling technology. Enable this option only when System Profile is set to Performance. The default option is set to 0.

Processor n Controlled Turbo

Displays the processor controlled turbo. Enable this option only when System Profile is set to Performance. The default option is Disabled.

Configurable TDP

Displays the configurable Thermal Design Power (TDP).

Maximum Memory Capacity

Displays the maximum amount of system memory supported by this processor.

Microcode

Displays the microcode update signature.
