This item is configurable only if the VGA Core Clock control option is set to Manual. (Note) This item is present only when you install a CPU that supports this feature. CPU Clock Ratio Allows you to alter the clock ratio for the installed CPU. The adjustable range is dependent on the CPU being installed. CPU NorthBridge Freq. Allows you to alter the frequency of the CPU North Bridge controller. Core Performance Boost (Note) Allows you to determine whether to enable the Core Performance Boost (CPB) technology, a CPU performance-boost technology. (Default: Enabled) CPB Ratio (Note) Allows you alter the ratio for the CPB. The adjustable range is dependent on the CPU being installed. (Default: Auto) CPU Host Clock Control Enables or disables the control of CPU host clock. Auto (default) allows the BIOS to automatically adjust the CPU host frequency. Manual allows the CPU Frequency (MHz) item below to be configurable. Note: If your system fails to boot after overclocking, please wait for 20 seconds to allow for automated system reboot, or clear the CMOS values to reset the board to default values. CPU Frequency(MHz) Allows you to manually set the CPU host frequency.. This option is configurable only when CPU Host Clock Control is set to Manual. Important It is highly recommended that the CPU frequency be set in accordance with the CPU specifications. PCIe Spread Spectrum Enables or disables PCIe Spread Spectrum. (Default: Disabled) Set Memory Clock Determines whether to manually set the memory clock. Auto lets BIOS automatically set the memory clock as required. Manual allows the memory clock control item below to be configurable. (Default: Auto) Memory Clock This option is configurable only when Set Memory Clock is set to Manual. X5.33 Sets Memory Clock to X5.33. X6.66 Sets Memory Clock to X6.66. X8.00 Sets Memory Clock to X8.00. X9.33 Sets Memory Clock to X9.33. (Note) This item is present only when you install a CPU that supports this feature.
