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.

Important

HT Incoming Link Width

This field specifies the operation width of the incoming link.

HT Outgoing Link Width

This field specifies the operation width of the outgoing link.

HT Link Speed

This item allows you to set the Hyper-Transport Link speed. Setting to [Auto], the

system will detect the HT link speed automatically.

Adjust PCI-E Frequency (MHz)

This field allows you to select the PCIE frequency (in MHz).

Auto Disable DRAM/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)/ CPU-NB Voltage (V)/ CPU VDD Voltage (V)/ CPU-NB VDD

Voltage (V)/ DRAM Voltage (V)/ NB Voltage (V)/ SB Voltage (V)/ HT Link Voltage

(V)

These items are used to asjust the voltage of CPU, Memory and chipset.

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.
