Hilbert Hagedoorn at Guru3D has put together a pretty solid overclocking guide for the Titan X Pascal card. I guess if you have just sunk $1,200 of your hard earned pocket money on a new graphics card, you might as well make sure you’re getting every bit of performance out of it. Hilbert gives us a pretty complete picture of how much additional performance can be had from a Titan X on air cooling - turns out, there is quite actually quite a bit of headroom:
“Overclocking never comes without risk, but it sure as heck is interesting to see how far you can take a card. As such today an article dedicated on overclocking the Nvidia Titan X. You will notice that if you go for long lifespan that overclocking the old fashioned way will not disappoint. A good 1800~1850 MHz on the GPU (reference air cooler) is certainly something you can achieve reasonably easy. However with Nvidia's updated Dynamic Clock Adjustment technology (GPU Boost 3.0) things have changed a bit. Regardless of that you'll be able to tweak a lot more performance out of this complex 12 Billion transistor GPU, more than you think.”
