5.Voltage Regulator Output Selection (JP16-JP20)

These jumpers set the voltage supplied to the CPU. Determine whether your CPU has a single power plane or dual power planes and then the voltage that it uses. Current Intel CPU's marked "Pentium" has only a single power plane and uses the standard 3.38 volts (STD) or 3.5 volts (VRE). When a single power plane CPU is installed, the dual power plane selections will be automatically disabled. When a dual power plane CPU is installed, the single power plane selections will be automatically disabled. You may have one jumper on the Single Power Plane and another on the Dual Power Planes at the same time.
