MSI Z87-MPOWER-MAX manual Electromagnetic Interference problem

Chapter 3

▶Spread Spectrum

This function reduces the EMI (Electromagnetic Interference) generated by modulating clock generator pulses.

[Enabled]	Enables the spread spectrum function to reduce the EMI
	(Electromagnetic Interference) problem.
[Disabled]	Enhances the overclocking ability of CPU Base clock.

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.
