Pre-operating system management applications

Description

applications that need high utilization of random memory

access.

Enables or disables the hardware prefetcher. This option is set

to Enabled by default.

Enables or disables the Data Cache Unit (DCU) streamer

prefetcher. This option is set to Enabled by default.

Enables or disables the Data Cache Unit (DCU) IP prefetcher.

This option is set to Enabled by default.

Enables or disables the Sub NUMA Cluster. This option is set

to Disabled by default.

Specifies the MADT Core Enumeration. This option is set

to default in Round Robin. Linear option supports industry

core enumeration whereas, Round Robin option supports Dell

optimized core enumeration.

Enables you to get the memory read started early on DDR

bus. The Ultra Path Interconnect (UPI) Rx path spawns

the speculative memory that is read to Integrated Memory

Controller (iMC) directly. This option is set to Enabled by

default.

This option is set to Enabled by default.

Enables or disables the LLC Prefetch on all threads. This

option is set to Enabled by default.

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.

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.

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.

NOTE:

This feature is not supported if CPU Power

Management is set to Maximum Performance.

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 must dissipate. This

option is set to Normal by default.

NOTE:

This option is only available on certain stock

keeping units (SKUs) of the processors.

Enables you to reconfigure the processor using Dynamic

or Static Speed Select Technology. This option is set to

Disabled by default.

Enables you to reconfigure the processor using Speed Select

Technology.
