3a ( Fail ): Close Prime95 by right clicking the Prime95 icon “ Exit ” on the tray bar in the lower right side of your screen and selecting “ Exit ” . This closes Prime95 .
3b ( Fail ): 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 GIGABYTE 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 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 .
