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 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 adjustments 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 4.6GHz on Prime95 you can try setting AVX offset to 3. If using a newer version of Prime95 you can also set AVX 512 to 5. This will lower your CPU multiplier by 3x when running AVX and 5x when running AVX512 instruction sets. For instance if your CPU is set go 4.6GHz it will run at 4.4GHz when running AVX and 4.1GHz when running AVX512 programs. Step 3D (If System Shuts Down): AVX workloads such as Prime95 v27.9+ are some of the most demanding workloads to put on a processor. As a failsafe your system will shutdown if the CPU is drawing too much power. You can override this in the BIOS under Advanced Power Settings by setting CPU Vcore Current Protection to Extreme. This setting should only be used during carefully monitored benchmarking sessions. It should not be needed for normal daily workloads or gaming. 17
