If you finish one or a couple of gaming sessions without crashes, freezes, or force restarts, you’re good to go. Just remember to disable V-Sync and any framerate limit, then play a game for an hour or so. Titles such as Shadow of the Tomb Raider, GTA V, even CS: GO (the game isn’t too demanding, but it’s built-in a way to maximize CPU performance), or Rainbow Six Siege. The final step of CPU stress testing is playing CPU-intensive games. Finally, you can use Realbench for stress testing your GPU, but there are better tools for that. You also have access to the benchmark tool.
#Whats the point ogf a cpu stress test Pc
Once you run Realbench, the app will torture your PC with image editing in GIMP, x.264 image compression in Handbrake, and a heavy multitasking scenario as its final testing step. Great for triggering errors that other tools cannot detect. Realbench is a great stress test tool because it combines all kinds of CPU loads into one test. This should be the next-to-last step when stress testing your CPU after it passes synthetic and rendering stress test tools and manages to pass the Pi-calculator (Y-Cruncher), run Realbench. It’s a great way to test for stability, and you should let it run for a while after stress testing your CPU with other tools. It’s another synthetic benchmark, but we recommend it combined with Prime95/OCCT and Blender/Cinebench because it can find errors even when you successfully run other stress testing tools on this list. Y-Cruncher is a multithreaded Pi-compute simulator. As long as you have the option to set a custom render test duration, it doesn’t matter. You’ll notice we’ve put the R23 version in the list, but it doesn’t matter which version you’re using. We recommend just putting the multithreaded CPU test on loop (File->Preferences->Custom Minimum Test Duration) and running it overnight or for about an hour or so. Instead, it uses the Cinema 4D rendering engine, thus putting the CPU under real multithreaded loads that are better in detecting errors and instabilities than tools such as Prime95. This is another benchmark that isn’t synthetic. Cinebench R23Ĭinebench R32 is another excellent CPU stress test. Here’s a list of Blender demo files, many of which are pretty solid for testing the CPU and its limits. This way, you can test whether or not your CPU is ready for long and strenuous real-life multithreaded loads. If you can create or find a custom render that can strain the CPU overnight, that’s even better. Blender uses the CPU for 3D rendering, which means heavy loads but not unreasonably and unrealistically. The reason? Well, this isn’t a synthetic test that puts the CPU under unreasonable loads that would never happen in real life. We love Blender benchmark because it can detect errors on your CPU even after the CPU passes torture tools such as Prime95 or OCCT. Blender Benchmark and custom Blender Renders The included Linpack test is more demanding on the CPU, but it isn’t as good at detecting errors. You can leave the options at default values (small data set, extreme mode, stead load, auto instruction set, etc.) and let the test run for an hour or so. They are great for detecting stability issues. OCCT is a comprehensive stress testing suite that includes tests for every major component. For the best results, combine it with other tools (Blender, Cinebench, Y-Cruncher). Do not forget that Prime95 isn’t a perfect stress test. If you want to test both memory and CPU (if you OCed both the memory and the CPU), use the Blend test. Finally, WHEA errors are critical when stress testing and testing for stability, so make sure to monitor for those.Ī comprehensive test should last for about eight hours, but an hour of testing should be just fine if you’re in a hurry. And as a final step, use Realbench, which is excellent for simulating real-life CPU loads. For the best results, combine synthetic tests such as Prime95 or OCCT with real-life tests such as Blender.
When stress testing your CPU, never use a single or just a couple of tests. Let’s begin with the best stress testing tools for your CPU. There are dozens of apps for stress and stability testing out there but read on if you want a comprehensive list of the best PC stress testing tools for CPU, RAM, & GPU instead of spending hours scouring for the best ones.īelow you’ll find a selection of CPU, GPU, and RAM options, including heavyweights such as Prime95, Cinebench, 3DMark Suite, Unigine Heaven, or MemTest86, but also a couple of exciting tools that do their job better than most others but aren’t as popular. Stress testing PC components is a highly recommended procedure if you decide to overclock or undervolt your CPU and GPU, as well as when testing RAM for stability after applying an XMP or overclocking memory above its XMP certified specs.
