• When set to Standard mode, the entire
memory array will be scrubbed once in a
24-hour period.
• When set to Extended mode, the entire
memory array will be scrubbed every
hour to further increase system
reliability.
Memory Refresh Rate
• 1x
• 2x
The memory controller will periodically
refresh the data in memory. The frequency at
which memory is normally refreshed is
referred to as 1x refresh rate. When memory
modules are operating at a higher-than-
normal temperature or to further increase
system reliability, the refresh rate can be set
to 2x.
Uncore Frequency
• Dynamic
• Maximum
Selects the Processor Uncore Frequency.
Dynamic mode allows 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 Efficient Policy.
Note: This option is only available on systems
with Intel processors.
Energy Efficient Policy
• Performance
• Balanced Performance
• Balanced Energy
• Energy Efficient
Selects the Energy Efficient Policy.
The CPU uses the setting to manipulate the
internal behavior of the processor and
determines whether to target higher
performance or better power savings.
Note: This option is only available on systems
with Intel processors.
Number of Turbo Boost
Enabled Cores for
Processor 1(2,3,4)
All
Enables you to control the number of Turbo
Boost enabled cores for processor 1(2, 3, and
4). By default, the maximum number of cores
is enabled.
Monitor/Mwait
• Enabled
• Disabled
Enables you to enable/disable the
Monitor/Mwait instructions of the processor.
When set to disabled, these two instructions
are not supported by the processor.
Note: Monitor/Mwait can be disabled only
when C state is disabled in Custom mode.
When C state is enabled in Custom mode,
changing this setting does not impact system
power or performance.
Note: This option is only available on systems
with Intel processors.
