Feature Options Description
Auto Detect DIMM/PCI Clk
Enabled
Disabled
To reduce the occurrence of electromagnetic interference
(EMI), the BIOS detects the presence or absence of
components in the ISA and PCI slots and turns off system clock
generator pulses to empty slots.
Spread Spectrum
Enabled
Disabled
When the system clock generator pulses, the extreme values of
the pulses generates 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 and is therefore not
recommended.
