How long should you run a stress test on each of your components?
depends on what you are stressing and how hot it gets. for RAM, overnight. For CPU/GPU, unrealistically heavy stress for not longer than an hour. realistic full loads should be safe for indefinite use. More on reddit.com
What's the absolute best CPU GPU & RAM stress test software out there?
Apparently warzone because it's the only thing that successfully checks whether my system is stable after an overclock of any kind. I'll test with a bunch of software only to have my game crash as I'm nearing in on a win, then eventually relent and reset everything to stock. +1mhz on the gpu? warzone will crash +100 mhz on ram? warzone will crash +100 on cpu? warzone will crash More on reddit.com

August 22, 2023 -
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.
