I aim to help you with safely overclock your EVGA gtx 970 SSC ACX 2.0.
I don't want to risk damaging my GPU with unstable short spin life. I prefer to keep it safe and avoid any issues, especially when overclocked. How does a temperature around 40 to 50 degrees Celsius impact my GPU? Maxwell tends to handle heat poorly; the hotter it gets, the less performance it will have. Maintaining cool conditions is essential. Yes, higher ambient temperatures will negatively affect your overclocking.
Kriselkins shares his experience with an ACX 2.0 cooler and its powerful fans, achieving temperatures below 45 degrees Celsius. He recommends using Precision X over other overclocking tools for better compatibility. He suggests starting with a SSC 970 clocked at +100MHz with +100 MHz memory clock and +6mV, advising caution as higher speeds may cause instability. He asks for screenshots of the 1700+ core clock.
I've owned numerous GPUs, including two Nvidia 6800s I bought when FB2 was released. That's quite old. The first GPU I ever received wasn't a GPU at all—it was a graphics accelerator. The 6800s still function perfectly. I never ever overclocked them. My brother has a stable job and earns a lot of money. He buys GPUs and performs upgrades using MSI Afterburner or other Windows-based OC tools. He uses effective cooling solutions and rarely experiences problems. When newer models arrive, he swaps his GPUs. He's given me three sets that he ran in SLI and an individual card from a custom-built rig that wasn't SLI—it was extremely expensive. I can't recall the details and am too lazy to research further. He also assembled medium systems using cards like the Enthusiast GTX 460. So, regarding your question: the cards I've purchased have never failed. The ones my brother received were all OC'd while in his system. I receive them, they work for 3 to 18 months before failing. I fix them by removing the heat sink and plastic, preheating the oven to 385°C, and placing the card on a baking sheet with aluminum foil to support it. If you bake your GPU with the chips facing down, they'll fall out—definitely a problem. Researching baking cards has helped me in past attempts. Every time I tried this on a burned-out card, it worked. However, it doesn't last forever. Some needed re-baking after just weeks, while others lasted six months. Out of the five cards I've baked, every one required another bake. So, OC'ing them with higher voltage might reduce their lifespan, possibly due to heat or increased voltage effects. If you can install a top-notch cooling system, that could be the solution. Still, it's unclear if OC'ning them actually extends their life, or if it's just about performance gains. Maybe some cards are designed for OC, but I'm not a big supporter of overclocking GPUs. But I've tried Nvidia's old "Ntune," MSI Afterburner, and other tools to boost performance. It's uncertain whether OC'ning them shortens their life because of heat or another factor. If you can install an excellent cooling solution... that might be the key. Still, the real question is: what's the maximum gain you can achieve? Perhaps it's worth it only if you need that extra performance to make playing viable, but IMO... don't overclock GPUs unless absolutely necessary and you have proper cooling in place.
