BIOS Setup

▶ GT OverClocking

This item allows you to enable/ disable the overclocking of integrated graphics.

▶ GT Ratio

This setting controls the ratio of integrated graphics frequency to enable the integrated graphics to run at different frequency combinations.

▶ Adjusted GT Frequency

It shows the adjusted integrated graphics frequency. Read-only.

▶ 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.

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 over- clocked processor to lock up.
