! Spread Spectrum
This setting allows you to reduce EMI by modulating the signals the CPU gener-
ates so that the spikes are reduced to flatter curves. This is achieved by varying
the frequency slightly so that the signal does not use any particular frequency
for more than a moment. The choices are “Disabled” and “Enabled”.
