This one can sweat even the most powerful CPUs.Ĭheck out the best CPU stress test you can use below. The large FFTs test should be followed with a “Small FFTs” test, which is the most demanding CPU torture test found in Prime95. Next, when overclocking, first use the “Large FFTs” test to test your XMP memory profile.

If the app, or any of the threads, doesn’t crash or stop running, you’re fine. Important since most RAM modules nowadays use some sort of XMP. It combines all other tests and is great for new systems because this way you can test both the CPU and memory. When testing a new build, you can just select the “Blend” option. Now, when you open Prime95 you’re greeted with lots of different settings, so let us explain which settings to use depending on your use case. For instance, Mos sensors show you VRM temperature, which could throttle your CPU if it goes too high (over 90 degrees Celsius or higher). When it comes to the monitoring software, focus on CPU thermals but also thermal data from motherboard sensors.
