Step 2: Start Prime95 After starting the Prime95 torture test highlight the Prime95 tray icon—all cores should say “self-test”, if it shows “not working” that means that specific core has failed to pass the test. Another form of failing the stability test is that your system may simply just reboot or freeze, which means your settings were too aggressive and your CPU has failed the stability test. We normally test Prime95 for 1 hour. This duration can be increased for more assurance. Step 3a (Fail): Close Prime95 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 (Fail): Adjust Frequency or Voltage Now it’s time to 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 Control”. We recommend you to stay under 95° C on your CPU along with a CPU Vcore below 1.35 volts if possible. After making adjustments go back to Step 1. If it continues to fail dial down your “CPU Clock Control” until you pass stability testing. 9
