CPU Configuration
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
The CPU speed is determined by the CPU Ratio multiplied with the BCLK.
Increasing the CPU Ratio will increase the internal CPU clock speed without
affecting the clock speed of other components.
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.
CPU Cache Ratio
The CPU Internal Bus Speed Ratio. The maximum should be the same as the CPU
Ratio.
GT Frequency
Configure the frequency of the integrated GPU.
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 fre-
quency.
Intel SpeedStep Technology
Intel SpeedStep technology allows processors to switch between multiple frequen-
