MS-7033 M-ATX Mainboard
Frequency/Voltage Control
Use this menu to specify your settings for frequency/voltage control.
Current CPU Clock
It shows the current clock frequency of CPU. (Read-only)
Adjust CPU Ratio
End users can overclock the processor (only if the processor supports so) by
specifying the CPU ratio (clock multiplier) in this field. Setting options: Min: [8], Max: [50].
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 interference
(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,
set to [Enabled] for EMI reduction. Remember to disable Spread Spectrum 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. Setting options:
[Enabled], [Disabled].
