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,
activate the Spread Spectrum for EMI reduction. Remember to disable Spread Spec-
trum 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.
Options: [Disabled], [Enabled].
Adjust CPU Bus Clock (Mhz)
This item allows you to select the CPU Bus clock frequency (in MHz) and overclock
the processor by adjusting the FSB clock to a higher frequency. Settings are:
PSB 400:
100-355MHz.
PSB 533:
133-500MHz
PSB 800:
200-500MHz
DDR Clock (Mhz)
This read-only item allows you to view the current DDR clock.
Adjust AGP/PCI Clock (Mhz)
This item allows you to select the AGP/PCI clock frequency (in MHz) by adjusting the
AGP/PCI clock to a higher frequency.
DDR Power Voltage
Adjusting the DDR voltage can increase the DDR speed. Any changes made to this
setting may cause a stability issue, so
changing the DDR voltage for long-term
purpose is NOT recommended
.
AGP Power Voltage
AGP voltage is adjustable in the field, allowing you to increase the performance of
your AGP display card when overclocking, but the stability may be affected.
MSI Reminds You...
The settings shown in different color in
CPU Voltage (V), DDR Power
Voltage
and
AGP Power Voltage
helps to verify if your setting is
proper for your system.
White: Safe setting.
Yellow: High performance setting.
Red: Not recommended setting and the system may be unstable.
