Bclk Frequency; Spread Spectrum - ASROCK Z270 SUPERCARRIER User Manual

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
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.
Minimum CPU Cache Ratio
Set the minimum CPU Internal Bus Speed Ratio.

BCLK 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.
CPU Amplitude
Configure the CPU Amplitude.
CPU Slew Rate
Adjust the BCLK signal by defining the maximum change rate of the output voltage.
Higher values will result in a shorter signal rising time.
CPU PLL ORT
Configure the CPU PLL ORT.
Divider
The default is set to 4 where the max BCLK is 300 MHz, while divider 12 lowers the
max BCLK to 170 MHz, and divider 2 turns it into 300+ MHz.
