MSI Reminds You...
Dynamic OverClocking is an advanced overclocking function.
Any damage or risk resulted from impropriety or overclocking
is not guaranteed.
Spread Spectrum
When the motherboard 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 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. Available settings: Enabled, Disabled.
CPU Ratio Selection
This setting controls the multiplier that is used to determine the internal clock
speed of the processor relative to the external or motherboard clock speed.
CPU FSB Clock (Mhz)
This item allows you to select the CPU Front Side Bus clock frequency. The
field also allows you to overclock the processor by adjusting the FSB clock
to a higher frequency.
AGP/PCI Clock (MHz)
This item allows you to select the AGP/PCI clock frequency.
CPU Vcore Adjust
This setting is used to enable or disable the ability to adjust CPU Vcore for
overclocking purpose. Setting options: Yes, No.
CPU Vcore
Users can specify preferred CPU core voltage (Vcore) in this field if
CPU Vcore Adjust is preset to Yes.
