How far will the GTX 960 overclock?
How far will the GTX 960 overclock?
I notice many users achieving speeds above 60mhz on the core and 200mhz on memory, but is that truly the limit for the GTX 960? Could adjustments in voltage not push it further, or is this the maximum possible? Since I’m overclocking and temperatures remain steady across different voltages, but my clocks still feel a bit off during stability tests, and my timing isn’t quite what most people expect, how can I be sure the VRMS are being adequately cooled?
I wouldn't suggest handling the voltage. It doesn't matter how high or low your temperatures are; raising the voltage will speed up your GPU's wear. If it begins to produce artifacts, reduce the speed a bit until it stabilizes. That's your ideal performance limit.
Every system overclocks in its own way, even two identical GPUs. One might gain 100 milliseconds, while the other may not overclock at all.

I wouldn't suggest handling the voltage. It doesn't matter what your temperatures are; raising voltage will speed up wear on your GPU. If artifacts appear, reduce the voltage slightly until they stop. That's your ideal performance limit.
Each overclock behaves differently, even with two GPUs of the same type. One might gain 100mz more, while the other may not overclock at all.
I've heard everywhere that touching voltage is acceptable for two main reasons:
1. It provides extra margin, matching the card's needs based on the overclock settings
2. It contributes to heat generation. If your cooling system is sufficient, it won't cause significant additional degradation.
My hardware stays under 70 degrees Celsius, so I feel confident.
Beyond that, I've noticed that higher voltage also boosts my core clock, which seems to worsen the artifacts. Why would raising voltage actually increase my core clock? I assumed it was meant to help stabilize the overclock settings chosen by the user?

Not everything depends solely on temperature. Higher voltage accelerates the aging of your GPU circuits, shortening its lifespan.
Excessive voltage can offer some headroom, but only in certain cases. Every GPU has its own limits, which vary due to manufacturing inconsistencies.

Excessive voltage can offer some margin, but not always. Every GPU has a limit, and these vary due to manufacturing flaws.
UPDATE: I discovered the card's maximum voltage is 1.237, which seems low and stable based on my research. When I raised it to this level, my core clock increased, so I adjusted back to match the original max without voltage. The comparison showed the voltage significantly helped. It didn't even raise the temperature noticeably. Since the old unstable clock became stable, I pushed it further, achieving an extra 2mhz for a speed of 1512MHz. (I also managed over 200 on memory without artifacts. I'll keep experimenting.) This would be considered a solid overclock for the 960. Also, you mentioned overclocking reduces lifespan. True, but the card's longevity will still depend on its current relevance.

Temperature isn't the only factor. Higher voltage speeds up circuit wear, shortening the GPU's lifespan. Overvolting can give temporary headroom, but it's not a guaranteed solution. Every GPU has its limits, which vary due to manufacturing inconsistencies.
UPDATE: I discovered the card supports a maximum voltage of 1.237, which seems stable based on my research. When I pushed it to this level, my core clock increased, so I adjusted back to match the original max without voltage. The temperature remained unaffected. I then achieved an extra 2 MHz and reached 1512MHz with no artifacts. This was a solid overclock for the model.
Also, you mentioned that overclocking shortens lifespan. Technically true, but as long as the card remains relevant, its longevity is preserved.
TBH, anything below 50MHz won't noticeably affect performance.
