Cpu Configuration; Boot Performance Mode - ASROCK X299 Extreme4 User Manual

CPU Configuration

All Core Ratio
The maximum core ratio value that CPU core works on.
Per Core Mode
Per core mode is disabled by default.
CPU Mesh Max Ratio
Sets the maximum OC Ratio for the CPU Mesh Domain.
CPU Mesh Min Ratio
Sets the minimum OC Ratio for the CPU Mesh Domain.
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 Spread Spectrum
Enable BCLK Spread Spectrum to reduce electromagnetic interference for passing
EMI tests. Disable to achieve higher clock speeds when overclocking.

Boot Performance Mode

Select the performance state that the BIOS will set before OS handoff.
FCLK Frequency
Configure the FCLK Frequency.
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 SpeedStep Technology
Intel SpeedStep technology allows processors to switch between multiple frequen-
cies and voltage points for better power saving and heat dissipation.
Intel Speed Shift Technology
Enable/Disable Intel Speed Shift Technology support. Enabling will expose the
CPPC v2 interface to allow for hardware controlled P-states.
