Z170A-X1/3.1
CPU Configuration
Multi Core Enhancement
Improve the system's performance by forcing the CPU to perform the highest
frequency on all CPU cores simultaneously. Disable to reduce power consumption .
CPU Ratio
°e 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
°e CPU Internal Bus Speed Ratio. °e maximum should be the same as the CPU
Ratio.
Minimum CPU Cache Ratio
Set the minimum CPU Internal Bus Speed Ratio.
BCLK Frequency
°e 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 Spread Spectrum
Enable BCLK Spread Spectrum to reduce electromagnetic interference for passing
EMI tests. Disable to achieve higher clock speeds when overclocking.
Boot Performance Mode
Select the performance state that the BIOS will set before OS handoff.
Reliability Stress Restrictor
Disable or Enable Reliability Stress Restrictor feature.
FCLK Frequency
Configure the FCLK Frequency.
Intel SpeedStep Technology
Intel SpeedStep technology allows processors to switch between multiple frequen-
cies and voltage points for better power saving and heat dissipation.
