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.
DRAM Clock: Set the clock frequency of the DRAMs. The default is HOST CLOCK . You can select HCLK+33M
if your DRAM modules are faster than CPU (eg. a 66Mhz FSB CPU with a PC100 SDRAM or a 100Mhz FSB CPU
with PC-133 SDRAM) or select
HCLK-33M for a faster CPU with slower SDRAMs. This selection is indeed
important if you're thinking of overclocking a Pentium III to run beyond 133Mhz but only have PC-100 SDRAM
