H81M-DGS R2.0

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.
CPU Cache Ratio
The CPU Internal Bus Speed Ratio. The maximum should be the same as the CPU
Ratio.
CPU OC Fixed Mode
CPU OC fix mode allows you to keep the max CPU ratio as your setting without
throttling. Please note that overclocking may cause damage to your CPU and
motherboard. It should be done at your own risk and expense.
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.
Filter PLL Frequency
CPU BCLK Filter Frequency. Choose 1.6 for better overclocking capabilities.

Internal PLL Overvoltage

Enable for better stability when overclocking.
PCIE PLL Selection
Select SB PLL when overclocking.

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.
