Owners Manual
Option Description
NOTE: All the parameters on the system prole setting screen are available only
when the System Prole option is set to Custom.
CPU Power Management Sets the CPU power management. This option is set to System DBPM (DAPC) by
default. DBPM is Demand-Based Power Management. Other options include OS DBPM,
Maximum Performance, and Hardware P States.
Memory Frequency Sets the speed of the system memory. You can select Maximum Performance, Maximum
Reliability, or a specic speed.
Turbo Boost Enables or disables the processor to operate in the turbo boost mode. This option is set to
Enabled by default.
Energy Ecient Turbo
Enables or disables the Energy Ecient Turbo option.
Energy Ecient Turbo (EET) is a mode of operation where a processor’s core frequency is
adjusted to be within the turbo range based on workload.
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. This option is set
to Enabled by default.
Write Data CRC Enables or disables the Write Data CRC. This option is set to Enabled by default.
Collaborative CPU Performance Control Enables or disables the CPU power management option. When set to Enabled, the CPU
power management is controlled by the OS DBPM and the System DBPM (DAPC). This
option is set to Disabled by default.
Memory Patrol Scrub Sets the memory patrol scrub frequency. This option is set to Standard by default.
Memory Refresh Rate Sets the memory refresh rate to either 1x or 2x. This option is set to 1x by default.
Uncore Frequency
Enables you to select the Processor Uncore Frequency option.
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 inuenced by the setting of the Energy Eciency Policy option.
Energy Ecient Polic
Enables you to select the Energy Ecient 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.
Number of Turbo Boot Enabled Cores for
Processor 1
NOTE: If there are two processors installed in the system, you see an entry for
Number of Turbo Boost Enabled Cores for Processor 2.
Controls the number of turbo boost enabled cores for processor 1. The maximum number
of cores is enabled by default.
Monitor/Mwait Enables the Monitor/Mwait instructions in the processor. This option is set to Enabled for
all system proles, 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.
