Step 5. CPU Core Voltage Adjust (JP15, JP16)

In case your CPU is running on a frequency higher then it is specified for, increasing its core voltage can enhance its stability. Over-clocking your CPU does however force your system to operate outside of its specifications, and therefore SOYO can not guarantee system stability.
