2.2.7Frequency/Voltage Control

2.2.7.1CPU Clock Ratio Unlock The choices: Disabled, Enabled.

2.2.7.2CPU Clock Ratio

The choice: 7X

2.2.7.3 Auto Detect PCI Clk

This allows you to enable or disable auto detect PCI clock. The choices are “Enabled” and “Disabled”.

2.2.7.4 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”.
