How to stability test
Step 1:
Open up CPU-Z, CoreTemp, and Prime95. Make sure Prime95 is configured. Click Custom, change“ Min FFT size( in K):” to 1344, and change“ Max FFT size( in K):” to 1344, then check“ Run FFTs in-place” and then press OK to start.
Step 2:
Start Prime95 and look at“ CPU Load” in the CoreTemp app. If one of your cores is not at 100 %, your system gets the blue screen of death or just freezes, that means your settings were too aggressive and your CPU has failed the stability test. We normally test for 1 hour. You can keep it running overnight for increased assurance. testing.
In the picture of the right Core # 1 is at 55 % which means this CPU has failed our stability testing.
