FSB/DRAM Ratio
This item allows you to set the FSB/DRAM ratio.
Adjusted DRAM Frequency (MHz)
It shows the adjusted DDR memory frequency. Read-only.
Adjust PCI-E Frequency (MHz)
This item allows you to set the PCI-E frequency (in MHz).
Auto Disable DRAM/PCI Frequency
This item is used to auto detect the DIMM/PCI slots. When set to [Enabled], the system will
remove (turn off) clocks from empty DIMM/PCI slots to minimize the electromagnetic
interference (EMI).
DRAM Voltage (V)
This item will allow you to adjust the Memory voltage.
Spread Spectrum
When the motherboard's clock generator pulses, the extreme values (spikes) of the pulses
create 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, 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
processor to lock up.
Important:
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.
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.
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.
