Z490 Extreme4 CPU Cache Ratio The CPU Internal Bus Speed Ratio. The maximum should be the same as the CPU 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. BCLK PEG/DMI Frequency The CPU speed is determined by the CPU Ratio multiplied with the BCLK PEG/ DMI. Increasing the BCLK PEG/DMI will increase the internal CPU clock speed but also affect the clock speed of other components. CPU PLL Spread Spectrum Enable Spread Spectrum to reduce electromagnetic interference for passing EMI tests. Disable to achieve higher clock speeds when overclocking. SRC PLL Spread Spectrum Enable Spread Spectrum to reduce electromagnetic interference for passing EMI tests. Disable to achieve higher clock speeds when overclocking. BCLK Advanced Setting Configure BCLK advanced settings. BCLK Aware Adaptive Voltage BCLK Aware Adaptive Voltage enable/disable. When enabled, pcode will be aware of the BCLK frequency when calculating the CPU V/F curves. This is ideal for BCLK OC to avoid high voltage overrides. Boot Performance Mode Select the performance state that the BIOS will set before OS handoff. FCLK Frequency Configure the FCLK Frequency. Ring to Core Ratio Offset Disable Ring to Core Ratio Offset so the ring and core can run at the same frequency. 59 English

Z490 Extreme4
CPU Cache Ratio
°e CPU Internal Bus Speed Ratio. °e maximum should be the same as the CPU
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 PEG/DMI Frequency
°e CPU speed is determined by the CPU Ratio multiplied with the BCLK PEG/
DMI. Increasing the BCLK PEG/DMI will increase the internal CPU clock speed
but also affect the clock speed of other components.
CPU PLL Spread Spectrum
Enable Spread Spectrum to reduce electromagnetic interference for passing EMI
tests. Disable to achieve higher clock speeds when overclocking.
SRC PLL Spread Spectrum
Enable Spread Spectrum to reduce electromagnetic interference for passing EMI
tests. Disable to achieve higher clock speeds when overclocking.
BCLK Advanced Setting
Configure BCLK advanced settings.
BCLK Aware Adaptive Voltage
BCLK Aware Adaptive Voltage enable/disable. When enabled, pcode will be aware
of the BCLK frequency when calculating the CPU V/F curves. °is is ideal for
BCLK OC to avoid high voltage overrides.
Boot Performance Mode
Select the performance state that the BIOS will set before OS handoff.
FCLK Frequency
Configure the FCLK Frequency.
Ring to Core Ratio Offset
Disable Ring to Core Ratio Offset so the ring and core can run at the same fre-
quency.
