CPU Configuration
AVX Ratio Offset
AVX Ratio Offset specifies a negative offset 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.
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.
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.
Intel SpeedStep Technology
Intel SpeedStep technology allows processors to switch between multiple frequen-
cies and voltage points for better power saving and heat dissipation.
Intel Turbo Boost Technology
Intel Turbo Boost Technology enables the processor to run above its base operating
frequency
when the operating system requests the highest performance state.
