8. Voltage Regulator Output Selection (VID0, VID1, VID2, VID3)
These jumpers set the VCORE voltage supplied to the CPU. Switching regulators
allow some jumper settings to be the same for two voltages of different power planes.
WARNING! Because CPU designs change rapidly, the table below is only intended as a simple
guideline and thus may not be true for your CPU. Always refer to the CPU documentation for
your CPU's voltage and then set the appropriate VID jumpers according to the illustration below.
