[. . . ] 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. IGXConfiguration CMOS Setup Utility-Copyright (C) 1984-2011 Award Software IGX Configuration UMA Frame Buffer Size VGA Core Clock control x VGA Core Clock(MHz) [Auto] [Auto] 600 Item Help Menu Level Enter: Select : Move F5: Previous Values +/-/PU/PD: Value F6: Fail-Safe Defaults F10: Save ESC: Exit F1: General Help F7: Optimized Defaults UMAFrameBufferSize VGA Core Clock control VGACoreClock(MHz) Frame buffer size is the total amount of system memory allocated solely for the onboard graphics controller. This item is configurable only if the VGA Core Clock control option is set to Manual. This item is present only when you install a CPU that supports this feature. - 24 - (Note) CPU Clock Ratio CPUNorthBridgeFreq. Allows you to alter the clock ratio for the installed CPU. 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. (Default: Disabled) CPU Host Clock Control CPUFrequency(MHz) PCIe Spread Spectrum Set Memory Clock Memory Clock Determines whether to manually set the memory clock. (Default: Auto) This option is configurable only when Set Memory Clock is set to Manual. X9. 33 Sets Memory Clock to X9. 33.

(Default) 2. 100V ~ 2. 900V The adjustable range is from 2. 100V to 2. 900V. Note: Increasing CPU voltage may result in damage to your CPU or reduce the useful life of the CPU. (Default) 1. 025V ~ 2. 135V The adjustable range is from 1. 025V to 2. 135V. [. . . ] 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". To create a new array, press <2> to enter the LDView/LDDefineMenu window. In the LDDefineMenu, use the up or down arrow key to move to an item for further configuration. [. . . ]
