Auto Dect DIMM/PCI Clk : This item allows you to enable / disable auto detect DIMM / PCI
Clock. The settings are "Enabled" and "Disabled".
Spread Spectrum Modulated: When the system clock generator pulses, the extreme values of
the pulse generate excess EMI. Enabling pulse spectrum spread modulation changes the extreme
values from spikes to flat curves, thus reducing EMI. This benefit may in some cases be
outweighed by problems with timing-critical devices, such as a clock-sensitive SCSI device.
CPU Host Clock/PCI Clock/ PC133 : This item allows you to select the CPU Host / PCI Clock.
The item you can select including 100/33MHz, 103/34MHz, 110/34MHZ, 115/38MHz and Default.
CPU Clock Ratio: This item allows you to set up the CPU clock ratio. This function depends on
your CPU specification and the change might not take affect due to the CPU specification
limitation.
