15 Best Tools to Stress Test CPU & RAM for PC

If you have got a new PC, or want to go through the components of your faulty PC, going through a CPU stress test or torture stress can let you know if everything inside your system is working correctly or not.

The stress test is done through software that pushes your system to its absolute limit or overclocking, which lets you know and give you exact details about your CPU parts and their working condition.

The reason why Stress testing is so important is that it helps you get to know about your faulty components or parts and gives you details of extreme load given to it and how it responds to the load, which eventually helps you next time when you play Games and start streaming.

There is software that helps you check specific parts like CPU, RAM, or GPU, and there is also software that stress-tests your PC overall and gauges the performance to broader circumstances.

But Before telling you about tools to stress-test your PC, there is one more thing which you should consider before Stress testing.

Hardware monitoring test.

If you know the computer hardware, you know that you can stress Tests by generating heavy loads and overclocking. Still, to ensure those details, you should monitor system temperature and load levels, which helps you to be aware while you are bench-marking your PC.

You can install these before Stress testing

  1. Core Temp
  2. GPU Z
  3. MSI Afterburner

So, today in this blog I will share 15 tools to stress Test your pc and give you a review of all the software’s I will recommend, in which some would be for free and some would cost you, you can choose according to your requirement, so let’s get into it.

Best 16 CPU Stress Test Tools:

#1 Prime 95

IntelBurn Test is another tool in the list in which it will help you stress test CPU and push its limits to the maximum capability to give you the working status.

Using Intelburn may simplify the usage of Intel Linpack, which is a useful program that puts even the most powerful PCs on its knees.

It gives real-time outputs on the screen and helps in system acknowledgment.

#5 Aida64 Extreme

stress test for pc

AIDA64 is the best stress testing software for beginners if you don’t have much idea about hardware and its components. This should be your go-to stress testing tool.

This is used for CPU, GPU, RAM overload testing, and it is paid software.

This tool is also preferred by many people in place of Prime 95 and helps starters check the power supply, voltage, and fan speeds without much hassle.

AIDA 64 is famous for its detailed information, which it can provide, and this is why it is a go-to stress testing tool for many users.

You can try AIDA 64 if applications like OCCT and Prime 65 is complicated for you.

#6 MemTest 64+

tech powerup ram stress test tool

MemTest 64 is another tool that helps in stress Testing your PC, and it majorly focuses on RAM more than other components. This is the best Application for checking RAMs’ highest potential and the highest load it can take.

If you face issues of bluescreen or sudden blackout, this is the Stress test you should go with.

#7 MemTest 86+ 

memory stress test tool

MemTest 86+ is another similar tool to the one I have discussed above, and this is again one more RAM specialization tool that helps in stress testing your RAM. In most cases, it will start giving an error in just a minute if your RAM has any faults. And if it passes one minute, there is a higher chance that your ram is in good condition.

#8 Heavy Load 

heavy load stress testing

HeavyLoad is a system Utility software that helps stress testing your CPU to give you the details regarding your system.

It is again effortless to use for beginners and can check out if you face issues with OCCT or other similar stress testing tools.

It uses simulated tasks to test your system under heavy load and gives you the exact status.

As I said above, it is very user-friendly for beginners and offers a very easy-to-understand dashboard. So if you are looking for a simple Stresstesting tool you can pick this one.

#9 Stress-ng 

Stress ng is another tool that helps you stress test your computer, but this is only applicable to Linux. So if you are a Linux user, this can be your go-to tool.

Stress ng helps make the CPU work hard and give out the hardware issues by stress testing, such as thermal overruns and operating system bugs, which occurs when the system is thrashed hard.

#10 PassMark Burnin Test

This is software to burn and load Test your software. It offers the best performance for benchmark PCs.

It has a free trial and paid version of the software, so you can use the free trial if you want to test the tool.
