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. DBPM is
Demand-Based Power Management.
Memory Frequency
Sets the speed of the system memory. You can select
Maximum Performance
,
Maximum Reliability
, or a
specific speed.
Turbo Boost
Enables or disables the processor to operate in the turbo boost mode. This option is set to
Enabled
by
default.
Energy Efficient
Turbo
Enables or disables the
Energy Efficient Turbo
option.
Energy Efficient 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.
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
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.
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 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.
