CPU BCLK Frequency The CPU speed is determined by the CPU Ratio multiplied with the BCLK. Increasing the BCLK will increase the internal CPU clock speed but also affect the clock speed of other components. BCLK Advanced Setting Press [Enter] to configure BCLK Advanced Setting. 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. Configuration options: [Enabled] [Disabled] Intel SpeedStep Technology Intel SpeedStep technology allows processors to switch between multiple frequencies and voltage points for better power saving and heat dissipation. Intel Speed Shift Technology Allows you to enable or disable the Intel Speed Shift Technology support. Enabling will expose the CPPC v2 interface to allow for hardware controlled P-states. To get the best support for Intel Turbo Boost Max Technology 3.0 (ITBMT 3.0), you have to enable Intel Speed Shift Technology. If your CPU does not support ITMBT 3.0, option will still be grayed out. Configuration options: [Enabled] [Disabled] Intel Turbo Boost Max Technology 3.0 Allows you to enable or disable the Intel Turbo Boost Max Technology 3.0 (ITBMT 3.0) support. Disabling will report the maximum ratio of the slowest core in _CPC object. Processors supporting the ITBMT 3.0 feature contain at least one processor core whose maximum ratio is higher than the others. Configuration options: [Enabled] [Disabled] Boot Performance Mode Default is Max Non-Turbo performance mode. It will keep cpu Flex-ratio till OS handoff. Max Battery mode will set CPU ratio as x8 till OS handoff. This option is suggested for BCLK overclocking. Configuration options: [Max Battery] [Max Non-Turbo Performance] [Turbo Performance] 24
