Introduction16English3-4 POWER BIOS FeaturesThis page lets you adjust various parameters to obtain improved performance for overclocking.Warning:Overclocking requires expert knowledge and risks permanent damage to system components.We recommend you leave these parameters at their default values for proper operation.CPU Overclock FrequencyEnables you to increment the CPU’s clock generator at 1 MHz step. This works together with CPU Clock Ratio (below)to set the CPU operating frequency.CPU Clock Generator x CPU Clock Ratio = CPU FrequencyFor example, if you have a processor that is rated at 2.4GHz and the clock generator is 200MHz, then 200MHz x 12= 2.4GHzOptions: 0 to 250 in 1MHz increments. Overclocking failure will cause no display on the monitor. To overcome this switch off the power supplyand switch on again. Restart the system, press and hold <Insert> key. This will revert the BIOS todefault or initial setting.PCIE ClockEnables you to subtle tune the PCI-E frequency at increments of 1MHz step.Options: 100 to 145 in 1MHz increments.CPU Clock RatioUse this item to select a multiplier to set the CPU frequency. See CPU Overclock Frequency item above for explanation.If your CPU multiplier is locked this option will be unavailable.AMD K8 Cool’n’QuietReduce the noise and heat from your PC when AMD’s Cool’n’QuietTM technology is Auto.Options: Auto, Disabled.CPU VoltageThis item allows you to adjust the CPU Vcore voltage.Options: Off, Auto, -0.200V to +0.500V in 0.025V increments. We recommend that you leave this at the defaultvalue.Chipset VoltageThis item allows you to adjust the Chipset voltage.Options: +1.2V to +1.5V in 0.1V increments. We recommend that you leave this at the default value.
