This option is configurable only if Init Display First under Advanced BIOS Features is set to PEG and an AMD/ATI graphics card is installed. (Default: Dis- abled) Allows you to determine whether to manually set the VGA Core clock. This item is configurable only if the VGA Core Clock control option is set to Manual. Allows you to set the CPU North Bridge frequency divisor. && CPU NB Clock Divisor (Note) Core Performance Boost (Note) CPB Ratio (Note) Allows you to determine whether to enable the Core Performance Boost (CPB) technology, a CPU performance-boost technology. Auto (default) allows the BIOS to automatically adjust the CPU host frequency. 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. 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. Allows you to determine whether to use the preset memory overclocking profile to achieve optimum overclocking performance. (Default: Disabled) Determines whether to manually set the memory clock. (Default: Auto) This option is configurable only when Set Memory Clock is set to Manual. Options are: X5. 33, X6. 66, X8. 00, and X9. 33. CPU Host Clock Control CPU Host Clock DRAM E. O. C.
