TVB Voltage Optimizations
This feature enables thermal base voltage optimizations for processors
that implement Intel Thermal Velocity Boost (TVB). The options are
Disabled or Enabled.
CPU feature
Hyper-Threading
This feature enables hyper-threading, which is a software method to
control logical processor threads. The options are Disabled or Enabled.
Boot Performance Mode
This feature controls the performance state that the BIOS will set intially.
The options are Max Non-Turbo Performance or Turbo Performance.
Intel(R) SpeedStep(tm)
Intel SpeedStep Technology 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 Disabled or 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 or Enabled.
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 or Enabled.
C states
C-state architecture, a processor power management platform devel-
oped by Intel, can further reduce power consumption from the basic
C1 (Halt State) state that blocks clock cycles to the CPU. Select En-
abled for CPU C-State support. The options are Disabled or Enabled.
Thermal Monitor
This feature enables the CPU thermal monitor. The options are Dis-
abled or Enabled.
