Table 1. Processor Settings detailsThis table provides the details of the options available on the Processor Settings screen.
Option	Description
Logical Processor	Each processor core supports up to two 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.
Virtualization Technology	Enables or disables the virtualization technology for the processor. This option is set to Enabled by default.
Kernel DMA Protection	This option is set to Disabled by default. When the option is set to Enabled, BIOS and Operating System will enable direct memory access protection for DMA capable peripheral devices using virtualization technology.
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.
LLC Prefetch	Enables or disables the LLC Prefetch on all threads. This option is set to Disabled by default.
Dead Line LLC Alloc	Enables or disables the Dead Line LLC Alloc. This option is set to Enabled by default. You can enable this 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.
x2APIC Mode	Enables or disables x2APIC mode. This option is set to Enabled by default. NOTE:For two processors 64 core configuration, x2APIC mode is not switchable if 256 threads are enabled (BIOS settings: All CCD, cores, and logical processors enabled). NOTE:x2APIC Mode has a dependency on Virtualization Technology. x2APIC Mode will take the setting assigned to Virtualization Technology and cannot be manually changed.
Number of Cores per Processor	This option is set to All by default.
Processor Core Speed	Specifies the maximum core frequency of the processor.

Table 2. Processor detailsThis table describes the settings available for each processor.
Option	Description

Brand	Specifies the brand name.
Level 2 Cache	Specifies the total L2 cache.
Level 3 Cache	Specifies the total L3 cache.
Number of Cores	Specifies the number of cores per processor.
Microcode	Specifies the processor microcode version.
