TheFunctionsofthe<F11>and<F12>keys(FortheMainMenuOnly) F11:SaveCMOStoBIOS This function allows you to save the current BIOS settings to a profile. First enter the profile name (to erase the default profile name, use the SPACE key) and then press <Enter> to complete. F12:LoadCMOSfromBIOS If your system becomes unstable and you have loaded the BIOS default settings, you can use this function to load the BIOS settings from a profile created before, without the hassles of reconfiguring the BIOS settings. First select the profile you wish to load, then press <Enter> to complete. - 24 - 2-3 MBIntelligentTweaker(M. I. T. ) IGXConfiguration CPUClockRatio CPU NorthBridge Freq.

Incorrectly doing overclock/overvoltage may result in damage to CPU, chipset, or memory and reduce the useful life of these components. This page is for advanced users only and we recommend you not to alter the default settings to prevent system instability or other unexpected results. (Inadequately altering the settings may result in system's failure to boot. If this occurs, clear the CMOS values and reset the board to default values. ) · When the System Voltage Optimized item blinks in red, it is recommended that you set the System Voltage Control item to Auto to optimize the system voltage settings.

Allows you to alter the frequency of the CPU North Bridge controller. 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.

The BIOS Setup menus described in this section may differ from the exact settings for your motherboard. The actual BIOS Setup menu options you will see shall depend on the motherboard you have and the BIOS version. C. ConfiguringRAIDsetinRAIDBIOS Enter the RAID BIOS setup utility to configure a RAID array. After the POST memory test begins and before the operating system boot begins, look for a message which says "Press <Ctrl-F> to enter RAID Option ROM Utility". [. . . ]
