CPU Configuration
CPU Ratio
The CPU speed is determined by the CPU Ratio multiplied with the BCLK. Increasing the CPU Ratio will increase the internal CPU clock speed without affecting the clock speed of other components.
CPU Cache Ratio
The CPU Internal Bus Speed Ratio. The maximum should be the same as the CPU Ratio.
BCLK/PCIE 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.
Spread Spectrum
Enable 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.
