Phoenix - AwardBIOS CMOS Setup Utility
DRAM Clock
The chipset supports synchronous and asynchronous mode between host
clock and DRAM clock frequency.
Settings: [By SPD, 100 MHz, 133 MHz, 166 MHz, 200MHz, 266MHz]
Auto Detect PCI Clk
Settings: [Disabled, Enabled]
Spread Spectrum
When the mainboard's clock generator pulses, the extreme values (spikes) of
the pulses create EMI (Electromagnetic Interference).
The Spread Spectrum
function reduces the EMI generated by modulating the pulses so that the
spikes of the pulses are reduced to flatter curves.
Settings: [Disabled, 0.20%, 0.25%, 0.35%]
