CPU Speed Auto detect the CPU speed from your system

Auto Detect DIMM/PCI Clk This option allows you to enable/disable the

feature of auto detecting the clock frequency of

the installed PCI bus.

Spread Spectrum When the motherboard’s 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 Enabled for EMI reduction. Remember

to disable Spread Spectrum if you are

overlocking because even a slight jitter can

introduce a temporary boost in clockspeed which

may just cause your overlock ed processor to

lock up.
