Features and Highlights

Stress CPU 
Use your processor, or even a certain amount of processor cores, to their utmost potential. It runs complicated computations to mimic the workload on your processor. 

Write a test file
Examine how your system handles depleting storage space. It writes a test file to your hard disk at varying speeds. You can choose the amount of remaining disk space; once that limit is reached, the file is overwritten again until more disk space is freed up. 

Allocate Memory 
You want to see how well your machine performs with limited memory? HeavyLoad can help by reserving memory and even allowing you to choose how much memory should be kept free and how quickly it is allocated. 

Simulate disk accesses
How much can your hard drive hold? Is it reliable? You may find out right now by using HeavyLoad and TreeSize Free's scan tool. It mimics a series of hits on files and directories across all local disks. 

Stress GPU
How does your graphics card withstand stress? The software allows you to fully utilize your graphics card processor. HeavyLoad employs a 3D produced graphic to mimic a high GPU load. Free Stress Test Software for Windows PCs!
