HeavyLoad

Bring your PC to its limits with the freeware stress test tool HeavyLoad. It puts your workstation or server PC under a heavy load and lets you test whether they will still run reliably.



The individual test methods employed by HeavyLoad for PC can be customized to fit your needs. On a system featuring multiple processor cores, for example, you can select how many of the available cores shall be used or set the speed in which the test file is to be written on your hard disk. Free Stress Test Software for Your Windows PC! Enjoy.

Overview

HeavyLoad is a stress testing utility developed by JAM Software. Designed to test the stability and performance of your PC, the app simulates high system load by utilizing various components such as CPU, RAM, hard disk, and network.



It is particularly useful for system administrators, developers, and power users who need to ensure their hardware and software can handle peak conditions. By putting your system under extreme conditions, it helps identify potential bottlenecks and weaknesses before they become critical issues.

Highlights

Stress CPU
Use your processor or even a specific number of processor cores to full capacity. It performs complex calculations to simulate the load on your processor.

Write Test File
Check how your system behaves when faced with dwindling disk space. It writes a test file to your hard disk with variable speed. You can define the amount of remaining disk space; once this limit is reached, It overwrites the file again and again until more disk space is freed up.

Allocate Memory
You would like to test how well your computer works with scarce memory? It can help: it reserves memory and even allows you to define how much memory should be kept free and how fast the memory should be allocated.

Simulate Disc Accesses
How much can your hard disk take? Is it reliable? With a combination of HeavyLoad and the scan function of TreeSize Free, you can find out today. It simulates a number of hits on files and folders on all local disks.

Stress GPU
How does your graphics card handle stress? With the program, you can utilize your graphics card processor to capacity. It employs a 3D rendered graphic to simulate a high load on the GPU. Free Stress Test Software for Your Windows PC!

Use HeavyLoad everywhere
Be mobile: Install this program as a portable version e.g. on a USB stick and use it wherever needed!
