2.10.1 Auto Detect PCI Clk
This allows you to enable or disable auto detect PCI clock. The choices are “Enabled” and
“Disabled”.
2.10.2 Spread 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 frequency slightly
so that the signal does not use any particular frequency for more than a moment. The
choices are “Disabled” and “Enabled”.
