Explaining GPU Overclocking and Stability Compared to CPU Overclocking and Stability
I've been experimenting to understand how to boost a GPU's performance. I managed to get some results with my CPU overclocking, but now I'm trying to assess if a GPU overclock will be reliable. The tools like Prime95 and OCCT provide clear feedback, yet running benchmarks doesn't always confirm stability. Thanks for your assistance.

I'm just testing for fun and figuring out if I should upgrade. Right now I'm boosting my score with 3dmark as much as I can. Will the artifacts show up in 3dmark too, like they do in the Heaven benchmark?
I usually prefer Heaven/Valley for stress and stability tests because they handle heavy loads better than 3dmark, which tends to run short tests with breaks.
But it's hard to say for sure. It might feel like CPU stress testing—you could be fine for half an hour, then fail in just a few minutes.
In short, yes, you can gradually increase the core voltage using MSI Afterburner as you would in BIOS.
When running a gaming benchmark without any visual issues or crashes, you're considered stable. For hardware-accelerated tasks, the standards might be stricter, though I'm not certain.
I'm just testing for fun and checking if I can get a better score. Are the artifacts visible in 3DMark too?
In short, just sit back and observe what happens. You can gradually increase the core voltage using MSI Afterburner, similar to how it's done in BIOS? The CPU and GPU each have their own voltage limits, so an OC guide can help you understand your card's capabilities. As mentioned, pushing the voltage beyond its limit isn't advisable. Continuously raising the voltage for extra core and memory speed isn't a wise approach once you've reached a satisfactory OC.
