Current CPU Clock
This item shows the current CPU Clock. Read only.
CPU Clock Ratio
This item allows you to adjust the CPU ratio. Setting range is from [8X] to [50X].
Auto Detect PCI Clk
This item is used to auto detect 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). Setting options: [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,
select Enabled for EMI reduction. Remember to disable Spread Spectrum function if
you are overclocking, because even a slight jitter can introduce a temporary boost in
clock speed which may just cause your overclocked processor to lock up key. Setting
options: [Enabled], [Disabled].
The items here includes some important settings of frequnecy, voltage and
overclocking functions.
