Bclk Frequency; Spread Spectrum; Long Duration Power Limit - ASROCK Rack C226M WS User Manual

BCLK Frequency

he CPU speed is determined by the CPU Ratio multiplied with the BCLK.
Increasing the BCLK will increase the internal CPU clock speed but also afect 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 ix 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 is Intel's new power saving technology. Processors can switch
between multiple frequencies and voltage points to enable power saving. he default value
is [Enabled]. Configuration options: [Enabled] and [Disabled]. If you install Windows®
TM
Vista / 7 / 8 and want to enable this function, please set this item to [Enabled]. his item
will be hidden if the current CPU does not support Intel(R) SpeedStep technology.
Please note that enabling this function may reduce CPU voltage and lead to system stability
or compatibility issues with some power supplies. Please set this item to [Disabled] if above
issues occur.
Intel Turbo Boost Technology
Use this item to enable or disable Intel Turbo Boost Mode Technology. Turbo Boost Mode
allows processor cores to run faster than marked frequency in specific conditions. The
default value is [Enabled].
Filter PLL Frequency
CPU BCLK Filter Frequency. Choose 1.6 for better overclocking capabilities.

Long Duration Power Limit

Conigure Package Power Limit 1 in watts. When the limit is exceeded, the CPU
ratio will be lowered ater a period of time. A lower limit can protect the CPU and
save power, while a higher limit may improve performance.
