Bclk Frequency; Long Duration Power Limit - ASROCK X99 Taich User Manual

CPU Cache Ratio
The CPU Internal Bus Speed Ratio. The maximum should be the same as the CPU
Ratio.
Minimum CPU Cache Ratio
Set the minimum CPU Internal Bus Speed Ratio.

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/PCIE Ratio
Configure PCIE/BCLK Ratio to prevent the PC from crashing when the internal
CPU clock speed and clock speed of other components are too high.
BCLK Spread Spectrum
Enable BCLK Spread Spectrum to reduce electromagnetic interference for passing
EMI tests. Disable to achieve higher clock speeds when overclocking.
SB Spread Spectrum
Enable SB Spread Spectrum to reduce electromagnetic interference for passing EMI
tests. Disable to achieve higher clock speeds when overclocking.
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 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.
Filter PLL Frequency
CPU BCLK Filter Frequency. Choose 1.6 for better overclocking capabilities.

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.
