Processor Settings details

About this task

The

Processor Settings

screen details are explained as follows:

Option

Description

Logical

Processor

Enables or disables the logical processors and displays the number of logical processors. If this option is

set to

Enabled

, the BIOS displays all the logical processors. If this option is set to

Disabled

, the BIOS

displays only one logical processor per core. This option is set to

Enabled

by default.

Alternate RTID

(Requestor

Transaction ID)

Setting

Modifies Requestor Transaction IDs, which are QPI resources. This option is set to

Disabled

by default.

NOTE:

Enabling this option may negatively impact the overall system performance.

Virtualization

Technology

Enables or disables the additional hardware capabilities provided for virtualization. This option is set to

Enabled

by default.

Address

Translation

Service (ATS)

Defines the Address Translation Cache (ATC) for devices to cache the DMA transactions. This option

provides an interface between CPU and DMA Memory Management to a chipset's Address Translation

and Protection Table to translate DMA addresses to host addresses. This option is set to

Enabled

default.

Adjacent Cache

Line Prefetch

Optimizes the system for applications that need high utilization of sequential memory access. This option

is set to

Enabled

by default. You can disable this option for applications that need high utilization of

random memory access.

Hardware

Prefetcher

Enables or disables the hardware prefetcher. This option is set to

Enabled

by default.

DCU Streamer

Prefetcher

Enables or disables the Data Cache Unit (DCU) streamer prefetcher. This option is set to

Enabled

default.

DCU IP

Prefetcher

Enables or disables the Data Cache Unit (DCU) IP prefetcher. This option is set to

Enabled

by default.

Logical

Processor Idling

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.

Configurable TDP

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

Nominal

by default.

NOTE:

This option is only available on certain stock keeping units (SKUs) of the processors.

X2Apic Mode

Enables or disables the X2Apic mode.

Number of Cores

per Processor

Controls the number of enabled cores in each processor. This option is set to

All

by default.

Processor 64-bit

Support

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

Processor Core

Speed

Specifies the maximum core frequency of the processor.

Process Bus

Speed

Displays the bus speed of the processor.

NOTE:

The processor bus speed option displays only when both processors are installed.

Processor 1

NOTE:

Depending on the number of CPUs, there may be up to four processors listed.

The following settings are displayed for each processor installed in the system:
