Chapter 4: UEFI BIOS
Configure SST-BF (Available when your CPU supports the Intel Speed Select
function and when "Activate SST-BF" is set to Enable)
When this feature is set to Enable, the system BIOS will configure SST-BF High Priority
Core settings so that system software does not have to configure these settings. The
options are Disable and Enable.
SpeedStep (P-States)
Enhanced Intel SpeedStep Technology (EIST) allows the system to automatically adjust
processor voltage and core frequency in an effort to reduce power consumption and
heat dissipation. Please refer to Intel's website for detailed information. The options are
Disable and Enable.
EIST PSD Function (Available when "SpeedStep (P-States)" is set to Enable)
This feature reduces the latency that occurs when one P-state changes to another, thus
allowing the transitions to occur more frequently. This will allow for more demand-based
P-state switching to occur based on the real-time energy needs of applications so that
the power-to-performance balance can be optimized for energy efficiency. The options
are HW_ALL and SW_ALL.
Turbo Mode (Available when "SpeedStep (P-States)" is set to Enable)
Select Enable to allow the CPU to operate at the manufacturer-defined turbo speed by
increasing CPU clock frequency. This feature is available when it is supported by the
processors used in the system. The options are Disable and Enable.
CPU Flex Ratio Override (Available when "SpeedStep (P-States)" is set to
Enable and when your CPU supports this feature)
Select Enable to override the CPU Flex-Ratio setting, which is the minimum multiplier
that allows the computer to clock. The options are Disable and Enable.
CPU Core Flex Ratio (Available when "CPU Flex Ratio Override" is set to Enable
and when your CPU supports this feature)
Use this feature to configure the Core Ratio Multiplier settings for non-Turbo mode pro-
cessors. The default setting is 23.
