SM_VCC is the supply voltage used for the SMBus functions and for the VID output signal circuits. The VID signals are programmed by Intel during the manufacturing process so that the VRM output voltage will be set correctly.

PWR_OK will be deasserted when any output of an ATX12V-compliant or SSI-compliant power supply falls below regulation limits. It is important to maintain SM_VCC at any time the output of the VRM is enabled. Driving the VRM’s OUTEN with the PWR_OK signal will ensure correct sequencing at both power up...

If the processor needs to run at a lower core frequency, as must be done when a higher speed processor is added to a system that contains a lower frequency processor, the system BIOS is able to effect the change in the core to system bus ratio.
