Auto Detect DIMM/PCI Clk

This item is used to auto detect the DIMM/PCI slots. When set to Enabled,

the system will remove (turn off) clocks from empty DIMM/PCI slots to

minimize the electromagnetic interference (EMI). Settings: Enabled and

Disabled.

Spread Spectrum

When the motherboard clock 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, setting to En-

abled for EMI reduction. Remember to disable Spread Spectrum if you are

overclocking because even a 0.25% jitter can introduce a temporary boost in

clock speed of 25MHz (with a 1GHz CPU) which may just cause your

overclocked processor to lock up.
