Auto Disable PCI Clk
This item is used to auto disable the PCI slots. When set to [Enabled], the system will
remove (turn off) clocks from empty PCI slots to minimize the electromagnetic inter-
ference (EMI).
Spread Spectrum
W hen 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,
select the desired range for EMI reduction. Remember to disable Spread Spectrum
function if you are overclocking, because even a slight jitter can introduce a tempo-
rary boost in clock speed which may just cause your overclocked processor to lock
up.
M emory Voltage
Adjusting the memory voltage can increase the memory speed. Any changes made
to this setting may cause a stability issue, so changing the memory voltage for
long-term purpose is NOT recommended.
PCI Express Voltage
Adjusting the PCI Express voltage can increase the PCI-E speed. Any changes made
to this setting may cause a stability issue, so changing the PCI-E voltage for
long-term purpose is NOT recommended.
Adjust DDR Memory Frequency
This item allows you to select the DDR memory frequency (in MHz) and overclock the
processor by adjusting to a higher frequency.
Adjust CPU FSB Frequency
This item allows you to select the CPU Front Side Bus clock frequency (in MHz) and
overclock the processor by adjusting the FSB clock to a higher frequency.
