Cpu Configuration; Spread Spectrum - ASROCK H97M User Manual

H97M
Load Optimized GPU OC Setting
You can use this option to load optimized GPU overclocking setting. Please note that
overclocking may cause damage to your GPU and motherboard. It should be done at your
own risk and expense. This option appears only when you adopt K-Series CPU.

CPU Configuration

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.
BCLK/PCIE 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.

Spread Spectrum

Enable Spread Spectrum to reduce electromagnetic interference for passing EMI
tests. Disable to achieve higher clock speeds when overclocking.
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.
