Thermal Voltage Boost (TVB)
TVB Ratio Clipping
This feature enables CPU core frequency reduction for processors that implement Intel
Thermal Velocity Boost (TVB). For overclocking, this feature must be
Disabled
.
TVB Voltage Optimizations
This feature enables thermal base voltage optimizations for processors that implement Intel
Thermal Velocity Boost (TVB). The options are Disabled and
Enabled
.

and Turbo Performance.
Intel(R) SpeedStep(tm)
Intel SpeedStep Technology allows the system to automatically adjust processor volt-
age 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 Disabled and
Enabled
.
Race To Halt (RTH)
This feature enables Race To Halt, which dynamically increases CPU frequency in order
to enter package C-State faster. This will reduce overall power consumption. The options
are Disabled and
Enable
d.
Intel(R) Speed Shift Technology
This feature enables Intel Speed Shift, which allows the operating system to hand control
of CPU frequency and voltage to the processor. This increases P-state change speed
and improves power efficiency. The options are Disabled and
Enabled
.
