Before you start
GPU stress tests can significantly increase GPU load, temperature, power draw and fan speed.
Stop the test if your system becomes unstable, overheats, crashes or behaves unexpectedly. Do not run extreme tests on hardware with known cooling problems. This website cannot guarantee hardware safety.
This is a deliberately punishing test. It can push your GPU to its thermal and power limits for minutes.
- Laptops: plug in the charger and make sure the vents are clear.
- Make sure your GPU is cooled properly. Do not run this with known fan or cooling problems.
- Save your work and close other important tabs. A weak or overheated GPU can make the screen flicker or the graphics driver reset, which may close apps.
- You can stop at any time with the Stop button or the Escape key. The test also stops itself if frames take more than two seconds.
Long run: this test keeps the GPU busy for five minutes or more, so your computer will get warm. Laptops should be plugged in. You can stop at any time with the Stop button.
Shader, memory, geometry, integrity and limit phases in one session, ending with a single PASS, WARNING or FAIL verdict. Takes 5, 10 or 15 minutes.
About this test
Six back-to-back phases in one session: shader math, memory bandwidth, geometry, integrity under load, a limit search and a repeat of the first phase. It ends with one PASS, WARNING or FAIL verdict. A run takes 5, 10 or 15 minutes.
It needs an acknowledgement before it starts and has an always-visible Stop button. It cannot read temperatures and cannot prove long-term stability.
How to read the results
PASS means no errors and no meaningful slowdown across the phases. WARNING means the repeat of the first phase was 7 to 15% slower than the original, or a phase had to be reduced, skipped or stopped early. FAIL means the integrity phase saw errors, the graphics context was lost, a phase failed or the repeat was more than 15% slower. The summary lists each phase so you can see where it went wrong.
Frequently asked questions
Which duration should I choose?
Five minutes for a quick overall look, ten for most checks and fifteen for a thorough soak.
What does the repeat of the first phase show?
If the GPU is slower the second time, heat or power limits probably built up during the session.
What if it ends with WARNING?
Look at the phase list. Check cooling and power mode, and run again. A consistent warning is worth investigating.
Is it safe?
It is heavy, so it asks for confirmation and always shows Stop. Close other work first and stop if the system becomes unstable.
Can I run it on a laptop?
Yes, plugged in and with clear vents. Expect lower limits than a desktop.
