Long Duration Maintained - ASROCK Z170 PRO4/D3 User Manual

Z170 Pro4/D3
Minimum CPU Cache Ratio
Set the minimum CPU Internal Bus Speed Ratio.
BCLK Frequency
The 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 Spread Spectrum to reduce electromagnetic interference for passing EMI
tests. Disable to achieve higher clock speeds when overclocking.
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.
Long Duration Power Limit
Configure Package Power Limit 1 in watts. When the limit is exceeded, the CPU
ratio will be lowered after a period of time. A lower limit can protect the CPU and
save power, while a higher limit may improve performance.

Long Duration Maintained

Configure the period of time until the CPU ratio is lowered when the Long
Duration Power Limit is exceeded.
Short Duration Power Limit
Configure 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.
System Agent Current Limit
Configure the current limit of the system agent. A lower limit can protect the CPU
and save power, while a higher limit may improve performance.
CPU Core Current Limit
Configure the current limit of the CPU core. A lower limit can protect the CPU and
