Auto Detect DIMM/PCI CLK

This item allows you to enable/disable auto detect DIMM/PCI

clock. The choices: Enable/Disable

Spread Spectrum

This allows you to enable/disable the spread spectrum modulate. When the system clock generator pulses, the extreme values of the pulse generate excess EMI. Enabling pulse spectrum spread modulation changes the extreme pulse spikes to flat curves thus reducing EMI.

The choices: Enable, Disable

Clock By Slight Adjust

This item allows you to select the CPU clock from 166 MHz to 100 MHz or 99 MHz to 66 MHz depending on the CPU host

clock.

CPU Clock Ratio

This item allows you to select the CPU ratio.
