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
Interconnect Bus default.
Link Power
Management
PCI ASPM L1 Enables or disables the PCI ASPM L1 Link Power Management. This option is set to Enabled by default.
Link Power
Management
Intel Persistent Controls the tuning function for Quality of Service (QoS) knobs. Disabled by default. Recipe 1 is
Memory CR QoS 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 Controls the thresholds that trigger switching between near (RDIMM/LRDIMM) and far (DCPMM)
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.

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.
