Table 47. System Profile Settings details
Option Description
System Profile Sets the system profile. If you set the System Profile option to a mode other than Custom,
the BIOS automatically sets the rest of the options. You can only change the rest of the
options if the mode is set to Custom.This option is set to Performance Per Watt (OS) by
default. Other options include Performance and Custom.
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. The options includes Maximum Performance and OS
DBPM.
Memory Frequency Sets the speed of the system memory. You can select Maximum Performance, Maximum
Reliability or a specific speed. 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.
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 Refresh Rate Sets the memory refresh rate to either 1x or 2x. This option is set to 2x 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. Maximum mode enables the maximum
uncore frequency.
Dynamic Load Line Switch Dynamic Load Line Switch control. Dynamic Load Line (DLL) is a Power Management
feature, which dynamically switches to the performance mode during periods of high CPU
utilization. This setting is read-only and set to Enabled when Optimized Power Mode is
Enabled. Read - Only unless System Profile is set to Custom.
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 when System Profile is set to Custom.
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.
PCI ASPM L1 Link Power
Management
Enables or disables the PCI ASPM L1 Link Power Management. This option is set to
Enabled by default.
Workoad Configuration This feature allows you to select a preconfigured workload profile. This option is set to
Balance by default.
