HeavyLoad doesn’t create the sort of deathly heat in a CPU that Prime95 does, but it does represent a more realistic maximum load. If you’re good with the default CPU+GPU option, just press the play button and the torture will commence. You can toggle which components should be stressed with the handy buttons on the toolbar. This is important if you want to check total system stability and are planning to use the computer for tasks that are heavy on both types of processor. One of the best things about this program is that you can choose to stress your GPU and CPU at the same time. Instead it’s an app that was built from the ground up to stress test computers. Unlike Prime95, HeavyLoad isn’t a repurposed scientific tool. Once you’ve run the CPU stress test for your desired time period (and there were no errors) you can press Test > Stop to give your poor CPU a break.

Your computer is now running the CPU at full throttle and you’ll hear the fans spin up momentarily to deal with the extra heat. Once you’re happy with these settings, just press OK and you should see this. Since our computer here has six cores with HyperThreading, we need 12 “workers” as they’re referred to in the app. The number of threads will be filled in automatically, but it should be equal to the number of cores in your system or double that amount if your CPU features HyperThreading. So if you want to focus on RAM, for example, you can. The “blend” option is best for general system testing, but as you can see some of the other options target specific components. When the program starts in stress testing mode, you get to make a few choices regarding the specific punishment. You can choose to opt out of this research project when you first run the program and you should do that if you’re only using it for stress testing. That is, a number that can only be divided by one and itself. The real purpose of Prime95 is to look for the largest prime number.

Prime95 is one of the toastiest pieces of software you can run on a computer. For the vast majority of people however, there are two general-purpose apps that have stood the test of time. Some are highly-specialized and might be suitable if your computer is built for the type of CPU tasks they cater to. There are plenty of applications out there which can help you light a fire under your CPU. Now the question is: Which stress testing tools should you use? The Best CPU Stress Test Tools # Stress testing is also useful even without overclocking to test a new cooling system. The short version is that an overclocked CPU has been set to a higher speed than the factory recommendation.Įvery time you overclock your CPU, you should stress test it to make sure that it doesn’t overheat or is unstable somehow.

Overlocking deserves to be looked at on it’s own and we have many articles on the subject. The second reason to run a stress test is as a way to validate CPU overclocking. The reasoning here is that if any components in the computer are faulty, they’ll fail during the burn-in period.

Some boutique PC building companies will have a “burn in” period, where the newly-built computer is continuously stressed for 24 hours. The first is to test a computer build after putting it all together. Generally there are two real-world scenarios where stress testing is common.

If there’s anything the CPU depends on or some subcomponent of the CPU that’s not doing well, a stress test will often reveal those problems in the form of crashes or a hanging computer. If they get too hot they can start making mistakes, or even become permanently broken. CPUs generate heat when they work and need to stay beneath a certain temperature. Why Stress Test Your CPU? #ĬPU stress tests are designed to push your CPU to its absolute limit and then check whether it can handle such a heavy workload.

You might be wondering why anyone would want to torture a poor CPU this way, but it’s actually an important part of various aspects of computer building and maintenance. Most real-world jobs, even those that use 100% of your CPU, don’t do it in this brutal, sustained way. The end result is a test of the very maximum work your CPU can do. It gives the CPU so many of these tough math problems that its full attention is taken up.

What Is a CPU Stress Test? #Ī CPU stress test is a software program that’s specifically designed to give your CPU incredibly hard problems to solve. That’s where CPU stress tests come into the picture. Whether it’s an intense online gaming session or an important video render that a client is waiting for, it’s crucial to know that your CPU can take the heat. The last thing you want is for your CPU to fall over right in the middle of something important.
