Precise CPU Stress

If you want to make sure your PC is stable and the installed cooling is adequate, running a stress test is the best way to go about it. If there are any issues, it is best to learn about them in a controlled benchmark than while doing something important.
Precise CPU Stress is a lightweight utility that enables you to test your CPU and RAM, while also monitoring resource usage and displaying the data in a real-time graph. It is easy to use and doesn’t need to be installed before launch.

Run your CPU and RAM at high load to discover potential issues

Whether you’ve overclocked your CPU or installed a new cooling system, putting it through a stress test is always recommended. If your processor can handle running at maximum load for an extended period, it is most likely stable, as no applications or games will be as taxing.
The stress level is customizable, so you can keep the resource usage a bit lower if you don’t want to go too hard on your CPU and RAM. The level can even be modified while a stress test is underway.

Monitor CPU, RAM and disk usage

The application tracks the current resource usage and displays the data in a real-time graph. Only readings from the last minute are shown, and the graph is updated once per second.
The main window can be configured to remain on top of all other applications, which is useful for continuous monitoring. You can also grab a screenshot of the graph is there is a particularly noteworthy event that you want to record.

Simple CPU and RAM stress test utility

Precise CPU Stress doesn’t offer as many features or customization options as other stress test tools, but it has the advantage of being remarkably easy to use. Even novices can set the program up and run a benchmark in seconds, though you should always monitor your system’s temperatures to make sure no components are running too hot.
