5) Voltage Regulator Output Setting (4x3 pin VID1 - 4)
This jumpers allow you to manually adjust the CPU core voltage. For each
jumper setting, there are two voltage options, depending on the CPU used.
The factory default sets all jumpers to [2-3], for use with JumperFree™ mode.

6) Voltage Regulator Output Limit (3 pin VID)
This jumpers offers extra security and control over the VID core voltage
settings. The default setting limits the voltage output to the default, and
does not allow any excess voltage emission to occur. Resetting the jumper
to [2-3] does not restrict voltage.
