2. Press F2 immediately after you see the following message:
F2 = System Setup
NOTE:
If your operating system begins to load before you press F2, wait for the system to finish booting, and then
restart your system and try again.
3. On the System Setup Main Menu screen, click System BIOS.
4. On the System BIOS screen, click Processor Settings.
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.
Virtualization
Enables or disables the virtualization technology for the processor. This option is set to Enabled by
Technology
default.
Adjacent Cache
Optimizes the system for applications that need high utilization of sequential memory access. This option
Line Prefetch
is set to 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
Software
Enables or disables the software 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
Prefetcher
default.
DCU IP
Enables or disables the Data Cache Unit (DCU) IP prefetcher. This option is set to Enabled by default.
Prefetcher
Sub NUMA
Sub NUMA Clustering (SNC) is a feature for breaking up the LLC into disjoint clusters based on address
Cluster
range, with each cluster bound to a subset of the memory controllers in the system. It improves average
latency to the LLC. Enables or disables the Sub NUMA Cluster. This option is set to Disabled by default.
UPI Prefetch
Enables you to get the memory that is read started early on DDR bus. The Ultra Path Interconnect (UPI)
Rx path will spawn the speculative memory that is read to Integrated Memory Controller (iMC) directly.
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
Enables or disables the Dead Line LLC Alloc. This option is set to Enabled by default. You can enable this
Alloc
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.
Logical Processor
Enables you to improve the energy efficiency of a system. It uses the operating system core parking
Idling
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 configure the TDP level. The available options are Nominal, Level 1, and Level 2. This
option is set to Nominal by default.
x2APIC Mode
Enables or disables the x2APIC mode. This option is set to Enabled by default.
NOTE:
This option is only available on certain stock keeping units (SKUs) of the processors.
