S3(STR) S3/Suspend To RAM (STR) is a power-down state. In this

state, power is supplied only to essential components
such as main memory and wakeup-capable devices. The
system context is saved to main memory, and context is
restored from the memory when a "wakeup" event
occurs.

S1 & S3 Depends on the OS to select S1 or S3.

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
