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
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.
Primary Plane Current Limit
Conigure the current limit of the CPU under Turbo Mode in ampere. A lower
limit can protect the CPU and save power, while a higher limit may improve
performance.
GT Frequency
Conigure the frequency of the integrated GPU.
GT Voltage Mode
Auto: For optimized settings.
Adaptive: Add voltage to the integrated GPU when the system is under heavy load.
