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 Interna l 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.

English

47

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 EMI

tests. 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.

Reliability Stress Restrictor

Disable or Enable Reliability Stress Restrictor feature.

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.

English

48

BCLK Aware Adaptive Voltage

Enable or disable BCLK Aware Adaptive Voltage. When enabled, pcode will be

aware of the BCLK frequency when calculating the CPU V/F curves. is is idea l 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

frequenc y.

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.

Intel Speed Shift Technology

Enable/Disable Intel Speed Shi Technology support. Enabling will expose the

CPPC v2 interface to allow for hardware controlled P-sates.

Long Duration Power Limit

Congure Package Power Limit 1 in watts. When the limit is exceeded, the CPU

ratio will be lowered aer a period of time. A lower limit can protect the CPU and

save power, while a higher limit may improve performance.

Long Duration Maintained

Congure the period of time until the CPU ratio is lowered when the Long

Duration Power Limit is exceeded.

Short Duration Power Limit

Congure Package Power Limit 2 in watts. When the limit is exceeded, the CPU

ratio will be lowered immediately. A lower limit can protect the CPU and save

power, while a higher limit may improve performance.

CPU Core Current Limit

Congure the current limit of the CPU core. A lower limit can protect the CPU and

save power, while a higher limit may improve performance.
