These jumpers set the VCORE voltage supplied to the CPU. Switching regula-
tors allow some settings to be the same for two voltages of different power
planes.

CPU. Always refer to the CPU documentation for your CPU’s voltage and then
set the appropriate VID jumpers according to the CPU Vcore Voltage Selection
illustration.
