Option

Description

Write Data CRC

Enables or disables the Write Data CRC. This option is set to Disabled by default.

Memory Patrol

Sets the memory patrol scrub frequency. This option is set to Standard by default.

Scrub

Memory Refresh

Sets the memory refresh rate to either 1x or 2x. This option is set to 1x by default.

Rate

Uncore

Enables you to select the Processor Uncore Frequency option.

Frequency

Dynamic mode enables the processor to optimize power resources across the cores and uncore during

runtime. The optimization of the uncore frequency to either save power or optimize performance is

influenced by the setting of the Energy Efficiency Policy option.

Energy Efficient

Enables you to select the Energy Efficient Policy option.

Policy

The CPU uses the setting to manipulate the internal behavior of the processor and determines whether

to target higher performance or better power savings. This option is set to Balanced Performance by

default.

Number of

Turbo Boost

Enabled Cores

for Processor 1

Controls the number of turbo boost enabled cores for Processor 1. The maximum number of cores is All by

default.

Monitor/Mwait

Enables the Monitor/Mwait instructions in the processor. This option is set to Enabled for all system

profiles, except Custom by default.

CPU

Enables or disables the CPU Interconnect Bus Link Power Management. This option is set to Enabled by

recommended for 2-2-2 memory configurations in App-Direct. Recipe 2 is recommended for other

memory configurations in App-Direct. Recipe 3 is recommended for 1 DIMM per channel configurations.

Intel Persistent

Memory

memory. BW Optimized, selected by default, optimizes for RDIMM/LRDIMM and DCPMM bandwidth.

Performance

Latency Optimized offers better RDIMM/LRDIMM latency in the presence of DCPMM. Balanced

Setting

Profile optimizes performance with Memory Mode-configured DCPMM.

System Security

You can use the System Security screen to perform specific functions such as setting the system password, setup password

and disabling the power button.

Viewing System Security

To view the System Security screen, perform the following steps:

Steps

1. Turn on, or restart your system.

Pre-operating system management applications

NOTE:

If there are two processors installed in the system, you will see an entry for Number of

Turbo Boost Enabled Cores for Processor 2.

NOTE:

This option can be disabled only if the C States option in the Custom mode is set to

disabled.

NOTE:

When C States is set to Enabled in the Custom mode, changing the Monitor/Mwait setting

does not impact the system power or performance.
