The following screen shows the Frequency and Voltage Control parameters and their default settings:

The following table describes the parameters found in this menu. Settings in boldface are the default and 
suggested settings.

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. 

Enabled

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.
