Frequency/Voltage Control - MSI K8MM-ILSR User Manual

Frequency/Voltage Control

Use this menu to specify your settings for frequency/voltage control.
Unused PCI Slot/DIMM Clk
This setting enables you to stop or activate the unused PCI slot & DIMM clock. Setting
options: Stop, Action.
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 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. Available options:
Enabled, Disabled.
CPU FSB Clock
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. Select the
number between 200~280 for needed frequency.
MSI Reminds You...
Changing CPU FSB clock could result in the instability of the system;
therefore, it is NOT recommended to change the default setting for
long-term usage.
