Step 3a (If Prime95 Fails): Close Prime95 by right clicking the Prime95 icon on the tray bar in the lower right side of your screen and selecting “Exit”. This closes Prime95. Step 3b (If Prime95 Fails): Now it’s time adjust your frequency or voltage settings. You can do this either through the BIOS or using EasyTune which is available through the GIGA- BYTE App Center. You have two options: Either increase CPU Vcore or decrease CPU Clock Ratio. We recommend you to keep CPU Vcore below 1.4 volts if possible. After making an adjustment go back to Step 1. If it continues to fail dial down your CPU Clock Ratio until you pass stability testing. Step 3C (If Prime95 Fails): If you aren’t stable at 5.3GHz on Prime95 you can try setting AVX offset to “2”. This will lower your CPU multiplier by 2x when running AVX instruc- tion sets. For instance if your CPU is set go 5.3GHz it will run at 5.1GHz during Prime95. Step 4 (Success): Congratulations, your current overclock is stable. You may want to try for a higher frequency. To do so, experiment with raising your CPU Clock Ratio and CPU Vcore settings either in BIOS or EasyTune and go back to Step 1 to ensure that it’s stable.
