Cpu Coniguration; Spread Spectrum - ASROCK Fatal1ty Z97X Killer Series User Manual

Fatal1ty Z97X Killer Series

CPU Coniguration

CPU Ratio
he CPU speed is determined by the CPU Ratio multiplied with the BCLK.
Increasing the CPU Ratio will increase the internal CPU clock speed without
afecting the clock speed of other components.
CPU Cache Ratio
he CPU Internal Bus Speed Ratio. he maximum should be the same as the CPU
Ratio.
BCLK/PCIE 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.

Spread Spectrum

Enable Spread Spectrum to reduce electromagnetic interference for passing EMI
tests. Disable to achieve higher clock speeds when overclocking.
CPU OC Fixed Mode
CPU OC ix mode allows you to keep the max CPU ratio as your setting without
throttling. Please note that overclocking may cause damage to your CPU and
motherboard. It should be done at your own risk and expense.
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.
