FSB/Memory Ratio
This setting control the ratio of CPU FSB / DRAM Clock Ratio to enable the CPU &
DRAM to run at different frequency combinations. Please note that the setting options
vary according to the CPU FSB Clock preset.
Adjusted DDR M emory Frequency
It shows the adjusted DDR memory frequency. Read only.
Auto Disable PCI Frequency
W hen set to [Enabled], the system will remove (turn off) clocks from any empty PCI
slots to minimize the electromagnetic interference (EMI).
Processor/ M emory Voltage (V)
These items allow you to adjust the processor/ memory voltage. Adjusting the voltage
can increase the speed. Any changes made to this setting may cause a stability
issue, so changing the voltage for long-term purpose is NOT recommended.
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 issue, 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 processore to lock up.
Important
1. 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 value of Spread Spectrum for EMI reduction.
2. The greater the Spread Spectrum value is, the greater the EMI is reduced,
and the system will become less stable. For the most suitable Spread
Spectrum value, please consult your local EMI regulation.
3. 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.
