Processor Settings details
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.
QPI Speed Enables you to control QuickPath Interconnect data rate settings.
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 by 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 by 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.
