AUTO DETECT PCI CLK:

This item allows you to enable or disable auto detect PCI Clock.

SPREAD SPECTRUM:

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.
