What is Stress Testing?

Stress testing your PC is a great way to find out what hardware is running when you get an unexpected shut down while playing a video game. It also shows you how much power your PC consumes and helps identify problems or areas that are causing bottlenecks when running intensive programs.

​With stress tests, you can check the frame rates of a build and see how much overhead they have. You can use stress tests to test the stability of your hardware and ensure the software is working properly at any time. There are also some great values that you can pick up that will help you optimize your build for specific tasks, or make it better suited towards virtual reality gaming.

The process is quite simple to follow. First, you need to know what you want to stress test. You also have to be aware of your system and the hardware that it has for this process.

Once you know what you are going to run a stress test on, the Advanced frequency tuner is going to help with the process. That will help you get started with getting some of the best options for running through stress tests.

💡 Do you know the right temperatures for stress testing?

  • If you are running a stress test on your CPU, you need to keep an eye on the temperature gauge and notice how fast it is reaching its limit. Even though the operating system will try to detect this and shut down your PC before more damage is done, hardware failure may still happen.

Hardware Monitoring Tools to Use While Running Stress Tests

Here I’m sharing a few programs that let you monitor your graphic card, CPU, and RAM during the stress test.

CPU Stress Test Tools

The CPU stress test tools, developed to test the reliability of a computer’s CPU, are being used by IT and software engineers to evaluate a system’s ability to respond in real-time. The software works by feeding the CPU with a high number of tasks that abruptly consume all of its resources. If it’s a powerful computer and the CPU is stable, system shutdowns are prevented and the system hums along without any glitches.

The goal of CPU stress testing tools is to assess whether a computer is fit for the job or not, and they do so by simulating actual work scenarios on standard software applications such as MS Excel, Photoshop, etc.

Here we’ve shared a list of the best CPU stress testing tools which help you in analyzing the stability of your CPU.

Which Stress Test Tool Should You Use?

There are a few different types of testing tools that can be used for stress testing. The more complex, expensive, and powerful the tool is, the better it can help you find out what your system’s performance is really capable of.

But here are a few tools that I liked most for stress testing;

  • AIDA64 Business Edition
  • Prime95
  • 3DMark

It’s important to note that when looking to stress-test your PC, you should always make sure that the software you’re using doesn’t overheat the system while running. Many heat issues are caused by the graphics card and CPU working too hard, so make sure to be careful of that.

💡 Important Thing to Remember

  • If anything goes wrong with your video card or CPU, it could potentially cause a computer crash or sluggish performance in general. The best way to avoid this is to use a quality stress test that doesn’t overheat your system.

Overall, using a stress testing tool like Prime95 will allow you to see the performance hit that something as simple as an upgrade could have on your computer. You can test your video card and CPU separately, or you can do both at once by combining stress tests.

Frequently Asked Questions (FAQs)

Here are a few frequently asked questions about stress testing which are generally asked by our readers.

Is Graphic Card Stress Testing Worth It?

The short answer is yes! Although it may not seem like it, every little bit helps. If your graphics card crashes while playing games, you could have a major problem with your hands.

It would be a lot better to stress test the card first and see if there are any performance issues before you try to upgrade or buy a new one. This will give you the information you need to know about your hardware before spending money on it.

Does it matter which program I use for stress testing?

The one we recommend is AIDA64, 3DMark, but if you’re looking for a free option, you can try FurMark, LinX, and CPUZ as well.

I’m switching to a new PC soon, and I want to stress test my current one first before I upgrade. If I do both, how can I do this?

Many video card stress test programs include automated testing that does not require you to start up a program manually. The best way to do this is to install the video card stress test software after you have installed your motherboard drivers and reboot the computer.

The program will automatically start up the testing when your computer starts up and should be ready for an instant stress test.

What to do if a GPU stress test creates errors during startup or crashes the system (GPU crashes)?

This is called a GPU crash, and it is when the card simply crashes and doesn’t allow the system to start at all. You are going to want to make sure that you look into this thoroughly before continuing.

You could have a faulty video card or bad RAM that is causing this, but you should also make sure to test out your motherboard and other parts of your system as well. If you are using anything else apart from the video card for a stress test, you should check to see if it is causing any problems at all.

What is the best way to run GPU stress tests?

There are many different ways to do this, but the simplest method would be by using software like Prime95. The program will automatically run when you start up your computer and test your graphics card without any extra effort on your part.

I have several game installs that are taking up almost 10GB of hard drive space, and I can’t get them off so easily because my graphics card crashes! How do I get around this?

It’s important to check that the video card you’re using is running at a stable operating temperature during heavy gaming sessions. The temperature of the GPU is one of the most important parts to stress testing, so make sure you get it right.

You’ll want to stay away from a variable speed fan or an entirely liquid-cooled system for this since they usually aren’t designed for intensive use. If you have a high-end card that can handle this kind of heat, though, you can do it without stressing your video card too much.

Wrapping Up

Stress testing your PC will let you know what you can expect from your computer when you’re playing a high-end game or running a software program that taxes the system. It is also important for a newly built PC for doing stress testing. The tests might also detect if your graphic card is underperforming and needs an upgrade or if it’s not performing as well as you expect it to, in which case, you can replace it with a better model.

If you’re looking to upgrade your existing system or start a new build, you can use these tools to make sure your components work in harmony and that your PC will have a long life ahead of it.

Remember that things might break one way or another during the process, and you’ll want to get out there as soon as possible if such problems arise. With these stress tests and programs, you’ll be able to know when everything is working correctly before throwing money at your PC or graphics card.
