Intel SpeedStep technology allows processors to switch between multiple frequen-
cies and voltage points for better power saving and heat dissipation.
Intel Turbo Boost Technology
Intel Turbo Boost Technology enables the processor to run above its base operating
frequency when the operating system requests the highest performance state.
Intel Speed Shift Technology
Enable/Disable Intel Speed Shift Technology support. Enabling will expose the
CPPC v2 interface to allow for hardware controlled P-sates.
Intel Turbo Boost Max Technology 3.0
Intel Turbo Boost Technology enables the processor to run above its base operating
frequency when the operating system requests the highest performance state.
Intel Thermal Velocity Boost Voltage Optimizations
This service controls thermal based voltage optimizations for processors that
implment the Intel Thermal Velocity Boost (TVB) feature.
Dual Tau Boost
Enable Dual Tau Boost feature. This is only applicable for CMLS 35W/65W/125W
skus. This item is only supported with processors with Config TDP support.
Long Duration Power Limit
Configure Package Power Limit 1 in watts. When the limit is exceeded, the CPU
ratio will be lowered after a period of time. A lower limit can protect the CPU and
save power, while a higher limit may improve performance.
Long Duration Maintained
Configure the period of time until the CPU ratio is lowered when the Long
Duration Power Limit is exceeded.
PSU Select Guide
Adjust CPU Power Limit and ICCMAX settings to avoid system reboot when using
low wattage power supplies.
