MS-7551 ▶ Adjusted HT Link Frequency (MHz) It shows the adjusted HT Link frequency. Read-only. ▶ Adjust PCI-E Frequency (MHz) This field allows you to select the PCIE frequency (in MHz). ▶ Auto Disable DIMM/PCI Frequency When set to [Enabled], the system will remove (turn off) clocks from empty DRAM/ PCI slots to minimize the electromagnetic interference (EMI). ▶ CPU Voltage (V)/ DRAM Voltage (V)/ NB Voltage (V)/ HT Link Voltage (V) These items are used to adjust the voltage of CPU, Memory and chipset. ▶ Spread Spectrum When the mainboard'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. 3-21

Adjusted HT L±nk Frequency (MHz)
It shows the adjusted HT L±nk frequency. Read-only.
Adjust PCI-E Frequency (MHz)
Th±s field allows you to select the PCIE frequency (±n MHz).
Auto D±sable DIMM/PCI Frequency
When set to [Enabled], the system w±ll remove (turn off) clocks from empty DRAM/ PCI
slots to m±n±m±ze the electromagnet±c ±nterference (EMI).
CPU Voltage (V)/ DRAM Voltage (V)/ NB Voltage (V)/ HT L±nk Voltage (V)
These ±tems are used to adjust the voltage of CPU, Memory and ch±pset.
Spread Spectrum
When the ma±nboard’s clock generator pulses, the extreme values (sp±kes) of the pulses
create EMI (Electromagnet±c Interference). The Spread Spectrum funct±on reduces the
EMI generated by modulat±ng the pulses so that the sp±kes of the pulses are reduced
to flatter curves. If you do not have any EMI problem, leave the sett±ng at D±sabled for
opt±mal system stab±l±ty and performance. But ±f you are plagued by EMI, set to Enabled
for EMI reduct±on. Remember to d±sable Spread Spectrum ±f you are overclock±ng
because even a sl±ght j±tter can ±ntroduce a temporary boost ±n clock speed wh±ch may
just cause your overclocked processor to lock up.
Important
If you do not have any EMI problem, leave the sett±ng at [D±sabled] for opt±mal system
stab±l±ty and performance. But ±f you are plagued by EMI, select the value of Spread
Spectrum for EMI reduct±on.
The greater the Spread Spectrum value ±s, the greater the EMI ±s reduced, and the
system w±ll become less stable. For the most su±table Spread Spectrum value, please
consult your local EMI regulat±on.
Remember to d±sable Spread Spectrum ±f you are overclock±ng because even a sl±ght
