HT Incoming/Outgoing Link Width

This item determines the width of the incoming/outgoing HT link. When set to [Auto], the system automatically determines the width of the HT link.

HT Link Speed

This item allows you to set the transfer speed over the HyperTransport link. When set to [Auto], the system automatically determines the speed of the HT link.

Adjusted HT Link Frequency (MHz)

This item displays the current frequency of the HT link. For reference only.

Auto Disable DRAM/PCI Frequency

When set to [Enabled], the system will disable unused PCI memory slots, which reduces electromagnetic interference (EMI).

DRAM Voltage (V)

This item allows you to adjust the memory voltage.

Spread Spectrum

Since the clock generator produces system clock pulses, its operation generates electromagnetic interference (EMI). The Spread Spectrum function reduces this interference by generating smoother pulses. If you do not have interference problems, leave this value at [Disabled] for better stability and performance. However,

if you encounter electromagnetic interference, enable this function by setting it to [Enabled]. Remember to disable the Spread Spectrum function if you are overclocking the system. This is necessary because even a slight jitter in the clock generator pulses can cause the overclocked processor to fail.

CAUTION

• If you do not have interference problems, leave this value at [Disabled] for better stability and performance. However, if you encounter electromagnetic interference, select Spread Spectrum for reduction. * The higher the Spread Spectrum value, the lower the level of electromagnetic interference, but the system will become less stable. Choose the appropriate value according to the EMI level set by legislation. * Remember to disable the Spread Spectrum function if you are overclocking the system. This is necessary because even a slight jitter in the clock generator pulses can cause the overclocked processor to fail.

Installation of values for mounting

The frequency settings for the system board can be adjusted by the user according to the installation instructions provided by the system manufacturer.
