Note that changing CPU Vcore could result in unstable system; therefore, it is not recommended to change the default setting for long-term purpose. CPU Clock Ratio End users can overclock the processor (only if the processor supports so) by specifying the CPU ratio (clock multiplier) in this field. Auto Detect PCI/DIMM Clk This item is used to auto detect the PCI slots. When set to Enabled, the system will remove (turn off) clocks from empty PCI slots to minimize the electromagnetic interference (EMI). Spread Spectrum When the motherboard'sclock generator pulses, the extreme values (spikes) of the pulses creates EMI (Electromagnetic Interference). The Spread Spectrum function reduces the EMI generated by modulating the pulses so that the spikes of the pulses are reduced to flatter curves. If you do not have any EMI problem, leave the setting at Disabled for optimal system stability and performance. But if you are plagued by EMI, set to Enabled for EMI reduction. Remember to disable Spread Spectrum if you 14

CPU VID
This item specifies the voltage of CPU Vcore. Note that changing CPU Vcore could result in unstable
system; therefore, it is not recommended to change the default setting for long-term purpose.
