  GPU volts:

  CPU VCORE NB VID Control, this is the main GPU voltage but it only requires a slight bump. Ideally, it should be tested gradually in +0.05 increments. This voltage can be pushed to 1.45v if there is sufficient cooling and if the GPU scales with volts. I've found with this particular A8-3850 CPU that it does not like going past +0.05 hence why I stress the importance of testing in small increments .

  CPU VDDP Voltage Control, helps stabilise GPU, memory and base clock at high frequency. This voltage in most cases can be left at 1.2v (stock) which is what was used in most of our test. We did see some gains when testing big memory clocks and used up to 1.28v to stabilise clocks. Raising higher to 1.3 can negatively affect main GPU voltage control. For max clocks a delicate balance is required between VDDP and core. Every APU will act differently with volts so generally look to increase VDDP only slightly (in +0.02 jumps).

  CPU VCORE Control is the main CPU voltage and as you increase the frequency voltage needs to be adjusted accordingly. We've found that you will gain generally 100Mhz with every 0.05v increase in VCORE but heat and silicone frequency limit may affect max clocks.
