Auto Detect DIMM/PCI CLK
This item allows you to enable/disable auto detect DIMM/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 pulse 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.
