Use this menu to specify your settings for frequency/voltage control.
Frequency/Voltage Control
Auto Detect PCI Clk
This option allows you to enable/disable the feature of auto detecting the
clock frequency of the installed PCI bus. The settings are: Enabled, Disabled.
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, activate the Spread Spectrum for
EMI reduction. Remember to disable Spread Spectrum if you are overclocking
because even a slight jitter can introduce a temporary boost in clockspeed
which may just cause your overclocked processor to lock up. Options: Disabled,
Enabled.
CPU Clock
This item specifies the clock frequency of CPU host bus (FSB), AGP (3V66)
and PCI bus. It provides a method for end users to overclock the processor.
Setting options: Give a DEC value by entering a number between maximum
233 MHz to minimum 200 MHz.
