Doing a overclock or overvoltage on CPU, chipsets and memory modules may result in damages or shortened life expectancy to these components. Please be aware that the M.I.T. menu items are for power users only. CPU Frequency (MHz) 200 ~ 500 Set CPU Frequency from 200 MHz to 500 MHz. (Default value: Auto) PCIE Clock (MHz) 100Mhz ~ 150Mhz Set PCIE Clock from 100 MHz to 150 MHz. (Default value: Auto) CPU Clock Ratio The adjustable range is dependent on the CPU you install. The option will display "Locked" and read only or will not show up if the CPU ratio is not changeable. DDR2 Voltage Control Please note that by overclocking your system through the increase of the DDR2 voltage, damage to the memory may occur. Normal Supply DDR2 voltage as DDR2 required. (Default value) +0.1V ~ +0.3V Increase DDR2 voltage by 0.1V to 0.3V. SB/PCIE Voltage Set the voltage settings for Southbridge and PCI Express bus. Normal Supply Southbridge and PCI Express bus voltage as Southbridge and PCI +0.1V ~ +0.3V Express required. (Default value) Increase Southbridge and PCI Express bus voltage by 0.1V to 0.3V. - 51 - BIOS Setup
