BIOS Setup
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.
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. Setting
options: For CPU FSB200: [200]~[500]
Adjust PCI Express Frequency
This item allows you to select the PCI Express frequency (in MHz). Select the number
between [100]~[133] for needed frequency.
CPU Dynamic OverClocking
Dynamic Overclocking Technology is the automatic overclocking function, included in
the MSI
TM ’s newly developed CoreCell TM Technology. It is designed to detect the load
balance of CPU while running programs, and to adjust the best CPU frequency
automatically. W hen the motherboard detects CPU is running programs, it will speed
up CPU automatically to make the program run smoothly and faster. W hen the CPU is
temporarily suspending or staying in the low load balance, it will restore the default
settings instead. Usually the Dynamic Overclocking Technology will be powered only
when users' PC need to run huge amount of data like 3D games or the video process,
and the CPU frequency need to be boosted up to enhance the overall performance.
Setting options:
The settings shown in different color in CPU Voltage, DDR Voltage and
NB Voltage help to verify if your setting is proper for your system.
[G r ay] Default setting.
[White] Safe setting.
[Yellow] High performance setting.
[Red] Not recommended setting and the system may be
unstable.
Changing CPU Voltage, DDR Voltage and NB Voltage may result in the
instability of the system; therefore, it is NOT recommended to change
the default setting for long-term usage.
