@Ellife - CPU-Z is misreporting the voltage, not sure why. If you look at my slightly slower submission: http://hwbot.org/submission/3562776_ ... you will see that I maxed the voltage in Ryzen Master. Could be Ryzen Master vs. BIOS voltage actually - CPU-Z was accurate on all the BIOS ones.
By the way, where are you based? Always good to see other Aussies on here.
