Description
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.
Sets the CPU power management. This option is set to OS DBPM by default. Other option
includes Maximum Performance.
Sets the speed of the system memory. You can select Maximum Performance or a specific
speed. This option is set to Maximum Performance by default.
Enables or disables the processor to operate in the turbo boost mode. This option is set to
Enabled by default.
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.
When set to Enabled, DDR4 data bus issues are detected and corrected during 'write'
operations. Two extra cycles are required for CRC bit generation which impacts the
performance. Read-only unless System Profile is set to Custom. This option is set to
Disabled by default.
Sets the memory patrol scrub mode. This option is set to Standard by default.
Sets the memory refresh rate to either 1x or 2x. This option is set to 1x by default.
Allows optimization of performance based on the workload type. The Workload Profile
setting is not a state. Setting a workload profile is a one-time action that in turns modifies
various BIOS settings to be optimized for the requested workload type. This option is set to
Not Configured by default.
Enables or disables the PCI ASPM L1 Link Power Management. This option is set to Enabled
by default.
Set the system determinism by Power Determinism or Performance Determinism. This
option is set to Power Determinism by default.
Efficiency Optimized Mode maximizes Performance-per-Watt by opportunistically reducing
frequency/power. Enables or disables the Efficiency Optimized Mode.
Enables or disables the Algorithm Performance Boost Disable (ApbDis). This option is set to
Disabled by default.
