I was a bit puzzled about how OC functions.

PSU is Corsair CX 750 watt semi-modular. It's approximately 4 to 5 years old, showing no signs of wear or problems. (no random restarts or power outages)
Adjusting the voltage slider to 100 from 0 usually has no effect. Moving it to 100 lets the card draw more voltage when needed, but this can lead to instability because each GPU is unique and some may not function properly at certain voltages. It's better to keep the slider at 0 for a stable operation—it often prevents more damage than achieving a stable overclock.
You might have set the power limit to maximum on your card. If so, it seems your GPU can't run above a higher overclock level. This isn't just about temperature; even if your card runs cooler, it can still become unstable beyond a certain point. This phenomenon is known as "silicon lottery," where variations in materials between batches affect performance. Some graphics cards, like certain 2080ti models, won't even reach 50 MHz overclocking, so you're likely lucky.
Conclusion: The issue is probably related to the GPU's maximum overclock capability, which is often capped at around 150 MHz. You can't change that, and performance differences will remain minimal.
yes, of course, but i was referring to cpu, there is a cpu bottleneck issue you're aware of?
i'll go into more detail. my friend has an i7 8700k and a budget compatible mobo that doesn't have everything—typically used for non-gaming pents (like H310). unfortunately, this kind of mobo can actually lower the cpu's clock speed in some games, which might reduce the performance of a powerful gpu like the RTX 2080 Ti. i'm not claiming it's the only case, but i'm just sharing what i've noticed from experience.
and as i read your recent reply, he actually has a high-end mobo, which means some possibilities have been ruled out. the user seems to have dropped the subject or forgotten about the load times on the gpu, so it's hard to say for sure. it might be like you mentioned before—some details are missing.
