Table 37. Processor Settings details (continued)

Option

Description

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.

Intel SST-BF

Enables Intel SST-BF. This option is displayed if Performance Per

Watt (operating system) or Custom (when OSPM is enabled)

system profiles are selected. This option is set to

Disabled

default.

Intel SST-CP

Enables Intel SST-CP. This option is displayed if Performance

Per Watt (operating system) or Custom (when OSPM is

enabled) system profiles are selected. This option is displayed

and selectable for each system profile mode. 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 cores configuration, x2APIC

mode is not switchable if 256 threads are enabled (BIOS

settings: All CCD, cores, and logical processors enabled).

AVX ICCP Pre-Grant License

Enables or disables AVX ICCP Pre-Grant License. This option is

set to

Disabled

by default.

Dell Controlled Turbo

Dell Controlled Turbo Settings

Controls the turbo engagement. Enable this option only when

System Profile is set to

Performance

Custom

, and CPU

Power Management is set to

Performance

. This item can be

selected for each system profile mode. This option is set to

Disabled

by default.

NOTE:

Depending on the number of installed processors,

there might be up to two processor listings.

Dell AVX Scaling Technology

Enables you to configure the Dell AVX scaling technology. This

option is set to

by default. Enter the value from 0 to 12

bins. The value that is entered decreases the Dell AVX Scaling

Technology frequency when the Dell-controlled Turbo feature is

enabled.

Optimizer Mode

Enables or disables the CPU performance. When this option

is set to

Auto

, set the CPU Power Management to Max

Performance. When set to

Enabled

, enables the CPU Power

Management settings. When set to

Disabled

, the CPU Power

Management option is disabled. This option is set to

Auto

default.

Number of Cores per Processor

Controls the number of enabled cores in each processor. This

option is set to

All

by default.

CPU Physical Address Limit

Limit CPU physical address to 46 bits to support older Hyper-V.

If enabled, automatically disables TME-MT. This option is set to

Enabled

by default.

AMP Prefetch

This option enables one of the Mid-Level Cache (MLC) AMP

hardware Prefetcher. This option is set to

Disabled

by default.

Homeless Prefetch

This option allows L1 Data Cache Unit (DCU) to prefetch, when

the Fill Buffers (FB) is full. Auto maps to hardware default

setting. This option is set to

Auto

by default.

Uncore Frequency RAPL

This setting controls whether the Running Average Power Limit

(RAPL) balancer is enabled or not. If enabled, it activates the

Pre-operating system management applications
