Frequency/Voltage Control
DRAM Clock
The chipset supports synchronous and asynchronous mode between host
clock and DRAM clock frequency.
Settings: [By SPD, 200MHz, 266MHz, 333MHz]
DRAM Timing
The value in this field depends on the memory modules installed in your
system. Changing the value from the factory setting is not recommended
unless you install new memory that has a different performance rating
than the original modules.
Settings: [Manual, Auto By SPD]
Auto Detect PCI Clk
Settings: [Enabled, Disabled]
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, Enabled]
