MSI X570-A PRO [48/160] Important

BIOS Setup

⚠

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.
