Best software for gpu stress testing?
Furmark can stress test your GPU, and it also has an artifact checker. It doesn't put as much stress on GPUs with raytracing, and doesn't test the VRAM at all, but it's another alternative. More on reddit.com

Hello,
I'm looking for recommendations on the best stress test software available for high end PC's.
CPU, GPU, RAM, etc.. everything.
I don't mind DL'ing multiple programs, a suite is also nice but not necessary. Currently looking at OCCT.
Anyone have any recommendations?
Thank you.

Quel est le meilleur logiciel pour le stress test de la carte ...
September 28, 2024 -
I wanted to stress test my gpu to check for stability and thought that ofcourse people who deal with overclocking also must know a bit about testing for stability.
My computer crashes (black screens, but rgb and fans stay on) after playing games for around 30m and this has happend for all the games I have tested so far.
Of course, I am running everything at stock and temps are okay, so I wanted to stress test my system to see if I could replicate the issue, and OCCT seems to be the recommended software to use, however it passes all the 1 hour tests, and I don't really want to pay to run it for longer. So, are there any good alternatives that I can let run overnight?

February 21, 2022 - I like Asus RealBench. Lightly stresses the gpu and includes avx instructions to stress cpu. More of a real world stress test. Prime95 is also very good. ... 3DMark is like the go-to for “professional” pc builders and testers, although it does cost money.
