You are going to really like the overclock potential of the GeForce GTX Titan, overall on air another 10% extra performance with the GPU in the 1100+ MHz range remains in a realistic realm of possibilities.
The new Boost features work out well, however let's be totally honest here, they are safetey features rather then tweaking features, really don't let Nvidia fool you. If you set the GPU temp target at 90 Degrees C, then once it hits that point it will start to downclock in one way or another. That's a safety feature, certainly not an overclock feature.
It is the same with the power limiter, you get an TDP assigned and once you pass that power signature it downclocks, not to help you with your overclock, contrary... to keep the card from frying itself. And that literally means that all GeForce GTX Titan cards based on a reference design will perform rougly the same with a certain set of parameters and thresholds.
Now, it is however still an awfull lot of fun to tweak and with Mhz ranges above 1100 MHz, who's complaining really?
Initially when we went for an overclock in our reference review article we hit roughly upto 1050~1100 MHz. Great, but that was being a little careful. With just a hint of extra voltage tweaking you can get in the 1100~1176 MHz range quite well. Overvolting is limited towards a very shy 1.2 Volts though, perhaps some board partners will set that limit a tad higher but right now from what we can see this is a locked limit set by NVAPI, meaning you get one Voltage step of 37mV on top of default which hardly is anything.
Anything over 1200 MHz we hardly could reach, and on our card really wasn't stable enough. But I forsee differnt dynamics with liquid cooling. Still even then it'll need more Voltage then what we get right now.
I stated with the GeForce GTX 680 that overclocking would never be the same again with the new Dynamic boost feature. I think it's safe to say that that statement has been validated. A lot, maybe too much has been restricted, but it's good to at the very least see some new voltage possibilities with Titan though. It remains to be a very tweakable card compared to its default clock frequency, and that's what the enthusiast crowd demands alright.
Overall the results don't lie, overclocking the GTX Titan is worth it as the card will jump up in performance quite a bit. So then my friends, we'll not to make this conclusion any longer then needed, the GeForce GTX Titan is impressive at many fronts and yes, tweaking equals fun. Heck even without voltage tweaking the Titan yields results by just fooling with temperature and power targets while the surrounding conditions like power limiters, heat and noise remain absolutely under control. That's free extra performance, at little extra risk or other displeasures (if you do it right). So grab yourself some tweaking software if you feel you want that additional performance, experiment a little -- we can definitely recommend that.
