& CPU EIST Function
(Note)
Enables or disables Enhanced Intel
®
Speed Step Technology (EIST). Depending on CPU loading, Intel
®
EIST technology can dynamically and effectively lower the CPU voltage and core frequency to decrease
average power consumption and heat production. AutoletstheBIOSautomaticallycongurethissetting.
(Default: Auto)
& Race To Halt (RTH)
(Note)
/EnergyEfcientTurbo
(Note)
Enables or disables the CPU power saving related settings.
& Voltage Optimization
Allows you to determine whether to enable voltage optimization to reduce power consumption. (Default:
Auto)
& Intel(R) Turbo Boost Technology
(Note)
Allows you to determine whether to enable the Intel
®
CPU Turbo Boost technology. Auto lets the BIOS
automaticallycongurethissetting.(Default:Auto)
& CPU Flex Ratio Override
Enables or disables the CPU Flex Ratio. The maximum CPU clock ratio will be based on the CPU Flex
Ratio Settings value if CPU Clock Ratio is set to Auto. (Default: Disabled)
& CPU Flex Ratio Settings
Allows you to set the CPU Flex Ratio. The adjustable range may vary by CPU.
& Frequency Clipping TVB
(Note)
Allows you to enable or disable automatic CPU frequency reduction initiated by Thermal Velocity Boost.

& Voltage reduction initiated TVB
(Note)
Allows you to enable or disable automatic CPU voltage reduction initiated by Thermal Velocity Boost. Auto
letstheBIOSautomaticallycongurethissetting.(Default:Auto)
d Active Turbo Ratios
& Turbo Ratio (1-Core Active~10-Core Active)
Allows you to set the CPU Turbo ratios for different number of active cores. Auto sets the CPU Turbo ratios
accordingtotheCPUspecications.ThisitemiscongurableonlywhenActive Turbo Ratios is set to
Enabled. (Default: Auto)
d C-States Control
& CPU Enhanced Halt (C1E)
Enables or disables Intel
®
CPU Enhanced Halt (C1E) function, a CPU power-saving function in system halt state.
When enabled, the CPU core frequency and voltage will be reduced during system halt state to decrease
power consumption. AutoletstheBIOSautomaticallycongurethissetting.Thisitemiscongurableonly
when C-States Control is set to Enabled. (Default: Auto)
& C3 State Support
(Note)
Allows you to determine whether to let the CPU enter C3 mode in system halt state. When enabled, the
CPU core frequency and voltage will be reduced during system halt state to decrease power consumption.
The C3 state is a more enhanced power-saving state than C1. AutoletstheBIOSautomaticallycongure
thissetting.ThisitemiscongurableonlywhenC-States Control is set to Enabled. (Default: Auto)
