Table 66. System Profile Settings details(continued)
Option Description
NOTE: All the parameters on the system profile setting screen are available only when
the System Profile option is set to Custom.
CPU Power Management Sets the CPU power management. This option is set to System DBPM (DAPC) by default.
Other option includes Maximum Performance, OS DBPM.
Memory Frequency Sets the speed of the system memory. This option is set to Maximum Performance by
default.
Turbo Boost Enables or disables the processor to operate in the turbo boost mode. This option is set to
Enabled by default.
Enery Efficient Turbo Energy Efficient Turbo (EET) is a mode of operation where a processor's core frequency is
adjusted within the turbo range based on workload. This option is set to Enabled by default.
C1E Enables or disables the processor to switch to a minimum performance state when it is idle.
This option is set to Enabled by default.
C States Enables or disables the processor to operate in all available power states. C States allow the
processor to enter lower power states when idle. When set to Enabled (OS controlled) or
when set to Autonomous (if hardware controlled is supported), the processor can operate
in all available Power States to save power, but may increase memory latency and frequency
jitter. This option is set to Enabled by default.
Memory Patrol Scrub Sets the memory patrol scrub mode. This option is set to Standard by default.
Memory Refresh Rate Sets the memory refresh rate, this option is set to 1x by default.
Uncore Frequency Enables you to select the Uncore Frequency option. Dynamic mode enables the processor
to optimize power resources across cores and uncores 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 Policy Enables you to select the Energy Efficient Policy option. 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.
Monitor/Mwait Enables the Monitor/Mwait instructions in the processor. This option is set to Enabled for all
system profiles, except Custom by default.
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.
Workload Profile This option allows the user to specify the targeted workload of a server. It allows
optimization of performance based on the workload type. This option is set to Not
Configured by default. Below is the list of available profiles:
● Not Configured
● HPC Profile
● Low Latency Optimized Profile
● Virtualization Optimized Performance Profile
● Virtualization Optimized Performance Per Watt Profile
● DataBase Optimized Performance Profile
● Database Optimized Performance Per Watt Profile
●
SDS Optimized Performance Profile
● SDS Optimized Performance Per Watt Profile
● Telco Optimized Profile
● NFVIFP Optimized Turbo Profile
● NFVIFP Energy-Balance Turbo Profile
