I've been overclocking my Powercolor 9070 XT Hellhound with settings of -70 mV, +10% power limit, 2614 MHz memory speed, and a custom fan curve that kicks up the RPM to around 1600 when the hotspot hits 90 degrees. My max power consumption is about 350W, and so far, I've seen about a 5% increase in FPS with no crashes during gameplay. I'm curious about the potential long-term effects and risks associated with running an overclocked GPU. Are there things I need to watch out for?

Generally, if you haven't experienced any catastrophic failures in the initial months, your GPU should be okay for its lifespan. Most manufacturers set power limits that are safe for the card, so typical software-based overclocking is fairly safe. That said, keep an eye on heat levels—especially with your hotspot hitting 90C. It's important to also monitor VRAM temps, as overheating can lead to issues over time.
From my experience, overclocking has been pretty stable, even running GPUs at max load for 24/7 since the days of the Radeon HD4870. With proper management of heat and moderate overclocking, it’s rare to run into severe issues nowadays. Just ensure you’re monitoring temps, and they stay within a reasonable range.
Thanks for sharing! I think my temps are okay since they only increased by about 2 degrees after overclocking. I'm using AMD Adrenaline to keep track of everything. You mentioned that overclocking sometimes allows the GPU to 'breathe'—could you explain that a bit more?
