6.24.1 DRAM Clock

This chipset supports synchronous and asynchronous mode between host

clock and DRAM clock frequency.

Settings: [By SPD, 400 MHz, 533 MHz]

6.24.2 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, +/- 0.1%, +/- 0.2%, +/- 0.3%, +/- 0.4%, +/- 0.5%, +/- 0.6%,

+/- 0.7%, +/- 0.8%, +/- 0.9%]
