3.10.1Spread Spectrum

This setting allows you to reduce EMI by modulating the signals the CPU generates so that the spikes are reduced to flatter curves. This is achieved by varying the fre- quency slightly so that the signal does not use any particular frequency for more than a moment. The choices are "Disabled" and "Enabled".
