I do a lot of rendering, and the vast majority of it is done on the GPU. Whenever I'm rendering something, GPU usage is clear up at 99-100% consistently. I've never overclocked before, as I've been too afraid to melt my CPU, and I don't really know what I'm doing either way. When I first wanted to overclock, it was way back when I was just trying to do it for video games, but the majority of people said when they overclocked, it was a 1-2 FPS difference, and was not worth the risk of damaging the computer.

Now that I'm doing Virtual and 3D Design, the GPU Overclocking is what I want to know about, because rendering at 2K in Substance Painter is giving me about 169 iterations per minute. My target number of iterations is 30,000 for most of my renders. I tried playing around with the "core clock" setting in MSI Afterburner, and I increased it to +30 and hit apply. I saw no difference in temperature, and no difference in fan speed. I then tried manually adjusting fan speed. I could set it to 100%, and while it was loud, my GPU temp went from 60 degrees Celsius to 50 degrees Celsius. So I know I can affect the GPU.

After that, I got nervous and figured I'd come here to get some answers first. (I tried youtube, but this community has always been more knowledgeable and more helpful). Thanks in advance!

EDIT: I attached a screenshot of my current Afterburner settings, in case that helps. I have no idea what the Base and Boost difference is either.

Hi, always provide information about your system when you post.

As for overclocking it, here: http://www.tomshardware.co.uk/answers/id-3735667/gtx-970-safe-overclock.html#21133296.

If your main use of the system is rendering, your better off getting a new GPU. Overclocking is not dangerous on newer systems and at most gives a 15% boost.

Here are my system specs:

CPU: Intel i7 8700k
GPU: GTX 1080 8GB VRAM
RAM: 1 x 16 GB Corsair Vengeance DDR4
MBoard: Asus Maximus X Hero
Cooling System: Cooler Master Hyper 212 Evo

And I'd love to get twin 1080 TIs, but as a college student, I just can't afford that right now. :/

Awesome, thank you! I'll try it out!
