HeavyLoad can load CPU, GPU, memory and storage. You set which parts are included and you can also use the test portable.

The load can disturb normal work. Save documents and track temperatures and free disk space during the test.

A load test helps to see how a system behaves when several components are active. Check feed and cooling in advance and use an appropriate testing environment. Keep an eye on temperature and response during the test.

A tax error has several possible causes. Therefore, do not change drivers, clock speeds and energy settings simultaneously. Test directed and record the conditions, so you can repeat and investigate a deviation.

Version and updates

Version 4.0 (Windows; ARM64 support added). The CPU test now uses matrix calculations instead of faculty calculations and the GPU test has also been tightened. Installation on ARM64 is supported. Errors on startup and graphical test have been repaired. Windows 8.1 and Windows Server 2012 R2 are no longer supported.

Compare HeavyLoad with alternatives

For a stability study, you need different information than for a performance comparison. A stress test load components are long-lasting, while a benchmark provides a score for a given test. Follow temperatures and use the correct component test; a single successful run does not exclude every hardware problem.

Software

What can it do?

Platform and licence

HeavyLoadYou are viewing this app

You charge components such as processor, memory and disk with adjustable tests. This helps to see how a system reacts to persistent loads.

WindowsFree to use

powerMAXView this alternative

You charge processor and graphics card to view temperature and stability behaviour. It's a stress test and not a replacement for a full diagnosis.

WindowsFree to use

BurnInTestView this alternative

You test multiple hardware parts with a commercial diagnostic package. The functions and test options depend on your edition.

Windows, LinuxPaid

OCCTView this alternative

You load and test various PC components with monitoring and error control. You can focus on which part of it causes problems under tax.
