Games never push your GPU to the same degree OCCT would, but you could still encounter instability issues from time to time. Loads are very different between games - while it would run fine in 9/10 games, the tenth game it starts to crash constantly. Answer from Jaba01 on reddit.com

July 11, 2025Should I use OCCT?
If the pc is working as you need it and your not overclocking right now, its not required or anything. If there is any instability occt will find it. So if you just wanna put the new parts through the gauntlet theres not much harm in it. Might highlight a problem that could be an issue later, and at least you'll be aware of it. More on reddit.com

r/overclocking on Reddit: How reliable is OCCT for a stability test?
February 6, 2025 -
Hello, I have a few questions about OCCT as a stability test. How reliable are these tests? I was testing my GPU overclock using the 3D Adaptive "extreme" test, testing various overclocks. I set +200 on core clock and +1500 on memory clock in MSI Afterburner. Other benchmarks and games were always stable but as soon as I ran the OCCT test it showed me a lot of errors. So I decreased core clock to +150 and left memory clock at +2000 and let it run for another half hour. This time I had no errors. Does this mean that my first overclock despite being stable in games was indeed NOT stable? And does that mean that my second overclock now should be in fact stable as there were no errors?

I’ve been overclocking my 5080. Using afterburner I passed OCCT, Furmark, 3DMark at +460 / + 2000. I played apex legends, cod and cyberpunk with no issue. I played Fortnite and that’s when the crashing started. I’m now down to 440/500 with 108 on power limit.

6 Reasons Why OCCT Is My Go-To Tool for Stress Testing CPUs and GPUs - Make Tech Easier
November 27, 2024 - While simple to start, it still offers FFT-based stress testing and advanced functions like Prime95. You can configure load type, instruction set, threading behavior, stress intensity, and many other vital functions. I won’t say it’s more powerful than a tool like AIDA64, but it does a great job of balancing simplicity and customization. One of the biggest reasons I prefer OCCT is its all-in-one nature.
