CrazyNutz it looks like you will have an opportunity to unlock the beast (Titan):

This TDP limit is 106% of Titan’s base TDP of 250W, or 265W. No matter what you throw at Titan or how you cool it, it will not let itself pull more than 265W sustained.

Overvolting is instead a set of two additional turbo clock bins, above and beyond Titan’s default top bin. On our sample the top bin is 1.1625v, which corresponds to a 992MHz core clock. Overvolting Titan to 1.2 means unlocking two more bins: 1006MHz @ 1.175v, and 1019MHz @ 1.2v. Or put another way, overvolting on Titan involves unlocking only another 27MHz in performance.

These two bins are in the strictest sense overvolting – NVIDIA doesn’t believe voltages over 1.1625v on Titan will meet their longevity standards, so using them is still very much going to reduce the lifespan of a Titan card – but it’s probably not the kind of direct control overvolting hardcore overclockers were expecting. The end result is that with Titan there’s simply no option to slap on another 0.05v – 0.1v in order to squeak out another 100MHz or so. You can trade longevity for the potential to get another 27MHz, but that’s it.

Ultimately, this means that overvolting as implemented on Titan cannot be used to improve the clockspeeds attainable through the use of the offset clock functionality NVIDIA provides. In the case of our sample it peters out after +115MHz offset without overvolting, and it peters out after +115MHz offset with overvolting. The only difference is that we gain access to a further 27MHz when we have the thermal and power headroom available to hit the necessary bins.

The bad part:

Those partners will have the option to release Titan cards with factory overclocks and Titan cards with different coolers (i.e. water blocks), but they won’t be able to expose direct voltage control or ship parts with higher voltages. Nor for that matter will they be able to create Titan cards with significantly different designs (i.e. more VRM phases); every Titan card will be a variant on the reference design.
