SATA Spread Spectrum feature.
The settings shown in different color in Adjust chipset Voltage item helps
to verify if your setting is proper for your system.
Gray: Default setting.
Yellow:High performance setting.
Red: Not recommended setting and the system may be unstable.
Changing any Voltage item may result in the instability of the system;
therefore, it is NOT recommended to change the default setting for long-term
usage.
Important
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.
