Auto Detect DIMM/PCI CLK
This item allows you to enable/disable auto detect DIMM/PCI
clock.
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.
Clock By Slight Adjust
This item allows you to select the CPU clock from 133 MHz to 166
MHz or 100 MHz to 133 MHz depending on the CPU host clock.
CPU Clock Ratio
This item allows you to select the CPU ratio.
