W480D2I / Z490D2I
BCLK Frequency
The CPU speed is determined by the CPU Ratio multiplied with the BCLK. Increas-
ing the BCLK will increase the internal CPU clock speed but also affect the clock
speed of other components.
BCLK PCIE/DMI Frequency
The CPU speed is determined by the CPU Ratio multiplied with the BCLK. Increas-
ing the BCLK will increase the internal CPU clock speed but also affect the clock
speed of other components.
CPU PLL Spread Spectrum
Select CPU PLL Spread Spectrum.
PCIE/DMI PLL Spread Spectrum
Select PCIE/DMI PLL Spread Spectrum.
BCLK Advanced Setting
Configure BCLK Advanced Setting.
When you enter this item, you see the followings:
CPU BCLK Amplitude
Select BCLK Amplitude for CPU.
PCIE/DMI BCLK Amplitude
Select BCLK Amplitude for PCIE/DMI.
100MHz BCLK Amplitude
Select BCLK Amplitude for SATA.
CPU1 Slew Rate
Adjust the BCLK signal by defining the maximum change rate of the output voltage.
Higher values will result ina shorter signal rising time.
PCIE/DMI Slew Rate
Adjust the BCLK signal by defining the maximum change rate of the output voltage.
Higher values will result ina shorter signal rising time.
