AVX is a more stressful workload that lower the AVX ratio to ensure maximum

possible ratio for SSE workloads.

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.

Ring to Core Ratio Oset

Disable Ring to Core Ratio Oset 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.
