CPU Conguration
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
aecting 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 aect the
clock speed of other components.
BCLK Spread Spectrum
Enable Spread Spectrum to reduce electromagnetic interference for passing
EMItests. Disable to achieve higher clock speeds when overclocking.
Boot Performance Mode
Default is Max Non-Turbo performance mode. It will keep cpu Flex-ratio till OS
hando. Max Battery mode will set CPU ratio as x8 till OS hando. is option is
suggested for BCLK overclocking.
FCLK Frequency
Congure the FCLK Frequency.
AVX Ratio Oset
AVX Ratio Oset species a negative oset from the CPU Ratio for AVX workloads.
AVX is a more stressful workload that lower the AVX ratio to ensure maximum
possible ratio for SSE workloads.
