cpu stress test

So you just spent days researching, purchasing, CPU stress test, and/or building the perfect new gaming or workstation PC. You’ve gone the whole nine yards, making sure the entire system is cable managed to a tee, your bright RGB LEDs are installed in just the right spots, and there’s plenty of airflow flowing through the entire system.

You power on your new PC and it seems to be working fine, but you want to make sure it’ll also be perfectly fine when the system has Battlefield loaded at the highest settings while streaming to Twitch for hours on end. Have a problem with an old computer aging system or overclocking any of the components when building the new computer? Here we suggest some software for RAM, a free CPU stress test, and a GPU stress test to install on your computer and check its stability. This is very important to ensure that your computer will work well, either in starting up or running programs.

This article is aimed at helping you overcome the problems with your CPU and GPU and ensuring that your computer’s programs will run well along with their stability. Thus, you need software dealing with the way you do that. In this guide, we are going to share the software you can use to overcome the problem, particularly in testing the system’s components. For instance, we are going to share the best CPU stress tester, the best RAM stress test, and the best GPU stress test.

Best CPU Stress Test For Windows PC

Check them all out below along with the additional information you may need. You may take note of some important information that may have many advantages.

1. Prime95


Looking for the best free cpu stress test? GIMPA developed Prime95 as a computing project to find new Mersenne prime numbers. It includes the torture test in the program to ensure accurate operation in the way of searching the numbers. Many hardware enthusiasts adopt the “torture test” to assist them in stressing their computer processors, particularly after they overclock the CPU and memory.

2. Aida64


What is the best overclocking software? Aida64 is one of the best software for CPU and GPU stress testing. Aida64 is a free CPU stress test that is widely used. Compared to the torture test offered by prime95 to push the operation in an unrealistic way, Aida64 comes more practically through its mimicking of real-world processes and is able to load up to 100% on the test.

The only downside of Aida 64 is the charge. Yeah, it is not free. Aida64 requires you to pay $34.99 for a handful of stress tests. This is not very expensive, but it is considered not ideal to take as an option among the users. Aida64 offers a 30-day trial which is available for free. You can actually optimize this feature to try the software when you really need to use it. When you are finished, you don’t have to pay for the software installation.

3. IntelBurn test


The next stress test for free GPU stress test you can try is the IntelBurn test. This is an ideal stress test tool you can use maximally to determine stability. Like Prime95, the IntelBurn test works further than necessary in pushing the processor. It can even more unnecessary stress on your computer’s processor than Prime95 does. More typically, the free GPU stress test is performed to check the CPU’s performance after running the full speed which is completely up to the maximum temperature. When you perform the CPU stress test, the cores inside the multi-core system will start to be used. later, the CPU will be tested with a justified and compatible workload. The second thing to know after the CPU stress test is the best free cpu stress test. There are always a variety of options dealing with GPU stress tests. Now you can try to push your GPU maximally by one of the following benchmarks.

4. Heaven and Valley Benchmarks

For your best free CPU stress test, heaven and valley benchmarks can be the first option on the list. It is formerly known as Unigine, too. This software is just one of the popular software to stress test your graphic card not only for stability but also after overclocking. It can also play a role as a synthetic benchmark to check how well your graphic card performs. Heaven and Valley benchmark is considered worth a GPU benchmark that offers VR features inside.

5. 3DMark


The second GPU stress test you can try is 3DMark. It is a widely used best free CPU stress test that comes along with many kinds of devices such as PCs, Laptops, tablets, phones, and many others. It also has a function to monitor the clock speed, load, framerate, and temperatures when each benchmark performs. You can get the basic edition of 3DMark for free. However, if you want the full version, you must pay  ̴$30 on Steam.

6. FurMark


FurMark is another GPU best free CPU stress test option you can try. Many enthusiasts do not prefer using this stress test due to the unrealistic amount of stress on the graphic card. FurMark can only be used for a short time. Many users say it is not the best option for your graphic card stress test. In shorts, a GPU stress test is performed to check its limits through the optimization of its full processing power utility.

Now it’s time for you to check out the best RAM stress test, too. In relation to the software for CPU, GPU stress test, this software works out your system’s memory not only to detect any issues that may occur in your RAM but also to check the computer’s stability after overclocking. Thus, its function is the same as CPU and GPU stress tests. There are two software or tools offered to stress test your RAM we are going to present in the following.

7. Memtest86

Memtest86 is the first RAM stress test you can try to test your system’s memory and solve any issues. There is also the Memtest86+ version. It was an offshoot of MemTets86 but it has not been updated since 2003, thus, it is no longer used now. If you want to stress-test your RAM, you can install and use this tool which is always updated.

8. Prime95 Blend Test

The second software you can choose to help you overcome issues on RAM is the Prime95 Blend test. It is a popular CPU stress test tool, however, the “blend” mode torture test serves the incredible RAM stress test. This tool is considered best for your RAM stability. Meanwhile, if you want to check the memory stability, Memtest86 is a better option. If you own an Intel CPU-based system, one of the best CPU stress testing tools actually comes directly from the company that manufactured your processor. Intel’s Processor Diagnostic Tool will verify the processor, its operating frequency, test all of its onboard functionality, then proceed to stress testing it in one of the most intense ways possible. This test can be set to run on a loop and the test can even be set to automatically shut itself down if the CPU overheats.

9. CPU-Z (Free)


CPU-Z is a great lightweight tool for checking the specifications of your CPU, memory, motherboard, and RAM and it’s almost always one of the first tools I install in any system I set up. Since it’ll most likely already be installed, I always also do a quick run of CPU-Z’s CPU stress test, which isn’t as intense as Prime95, but it does stress the CPU out enough that if you’re right on the edge in terms of stability, you’ll still have a chance to turn it down a notch.

10. Cinebench R20 (Free)

cpu stress test

Cinebench has been one of our favorite free benchmarking tools for years and with the long-overdue Cinebench R20 version, the test is now even more challenging thanks to a significantly more complex scene that must now be rendered.

Along with the increase in difficulty, Cinebench R20 now also features the capability to set a minimum time for the benchmark to run, which turns the benchmarking tool into an incredibly tough CPU stress test that simulates 3D video rendering loads. If you plan on using your PC for rendering video, 3D modeling, or photo editing, this test is definitely for you.

11. AIDA64 (Paid)

AIDA64 is a very comprehensive full system diagnostic utility typically aimed at engineers, IT professionals, and systems enthusiasts. Among other tools, one of the best tools AIDA64 offers is the System Stability Test which has the ability to stress everything from the CPU to RAM to the GPU.

What’s great about AIDA64 however, is that it will tell you if the CPU begins throttling, or slowing itself down when the temperatures are too high. If the CPU throttles, then it’s a good idea to check that the CPU cooler is properly installed, purchase a new cooler, or if you’ve been overclocking, it may be time to reduce the overclock.


Having read the review about software for CPU, GPU, RAM stress tests, you must find a conclusion that all the software is much recommended to use. They are all good along with their own features and ability to help you find a solution over the CPU and GPU stability.
