3a. Change CPU Vcore: Raising this helps keeps the system stable at higher CPU frequencies. However, it also increases the amount of heat your CPU produces. We suggest you to keep Vcore from 1.3 to 1.35v when overclocking to around 4GHz. 3b. Adjust the six new voltage settings: VCORE SOC, CPU VDD18, CPU SOC SB Voltage, 1.05V PROM Voltage, 1.8V SB Voltage, 2.5V PROM Voltage These are new settings that only exist on our AORUS X399 Chipset motherboards. For a little extra boost in stability while overclocking we suggest you to change VCORE SOC up to 1.3-1.35 volts when using standard air or liquid cooling. For the rest of the voltages we suggest you to leave them at Auto when using standard air or liquid cooling. If you still want to experiment raise them maximum +0.2V from their initials values. 3c. Adjust CPU Loadline Calibration Setting If you need some extra stability adjust this setting to either “Turbo” or “Extreme”. You may notice that after this adjustment your CPU Vcore is higher. 5
