3.10.1 CPU Clock Ratio
Key in a DEC number to set up the CPU Clock Ratio (Min=14; Max=17).
This item only shows up in special situations.
3.10.2 Spread Spectrum
This setting allows you to reduce the EMI by modulating the signals the
CPU generates so that the spikes are reduced to flatter curves. It achieves
this by varying the frequency slightly so that the signal does not use any
particular frequency for more than a moment. The choices are: "Dis-
abled," and “Enabled.”
