Minimum CPU Cache Ratio Set the minimum CPU Internal Bus Speed Ratio. BCLK Frequency he CPU speed is determined by the CPU Ratio multiplied with the BCLK. Increasing the BCLK will increase the internal CPU clock speed but also afect the clock speed of other components. BCLK/PCIE Ratio Conigure BCLK Ratio to prevent the PC from crashing when the internal CPUclock speed and clock speed of other components are too high. 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 frequencies 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 Conigure Package Power Limit 1 in watts. When the limit is exceeded, the CPU ratio will be lowered ater a period of time. A lower limit can protect the CPU and save power, while a higher limit may improve performance. Long Duration Maintained Conigure the period of time until the CPU ratio is lowered when the Long Duration Power Limit is exceeded. Short Duration Power Limit Conigure Package Power Limit 2 in watts. When the limit is exceeded, the CPU ratio will be lowered immediately. A lower limit can protect the CPU and save power, while a higher limit may improve performance. 60 English
