As long as you don't change the card's firmware or modify the card physically (like sodder stuff to the card) feel free to crank it all the way up on the graphics card.

Here's the catch, your card may or may not run at the overclocks you put it at despite the voltage you apply and that's cool man.

Here on OCN we acknowledge that not all cards are the same and that some overclock with almost no extra voltage and some cards just stick to stock.

These are hallowed web pages dedicated to overclocking and your question can be answered here and as for the 780 questions I'd leave it to Mad Pistol hes got one after all.

Locked voltage just means you have limited overclocking head-room on the GPU. You need unlocked voltage to be able to push your GPU to it's max potential and get extra performance. Some GPU's like the MSI lightning and EVGA Classified versions were made with unlocked voltage, but sold at about 50$ higher than the regular GPU's; however, due to the help of awesome OCN members, they were able to create a software that works with MSI's Afterburner to unlock the voltage on all GPU's with a specific voltage controller (NCP4206). The Asus versions are not made with this voltage controller, and so are the Gigabytes. The only one i am sure of is MSI, and i believe EVGA versions also use this controller.

This is the performance difference you can expect from locked and unlocked voltage on a GPU. Same system, same GPU before and after unlock.

Would graphics card's stock cooler removing and installing water block be counted as modding? biggrin.gif

Depends, some companies are very forgiving (EVGA you could "practically" [not literally] kill your card on purpose and they'd be like "its cool man just send back to us and we'll give a new one") dat customer service.

But if all you are doing is putting a water block on or removing the cooler I've never heard of a company rejecting/voiding a warranty. Its why there can be companies dedicated to GPU water cooling.

what company would you recommend? without voltage locks and with good customer service smile.gif (and not voiding warranty if installing water block wink.gif )

EVGA or MSI are the guys you want when you want the best. (unlocked voltage and Nvidia)

Just follow the overclocking guides (bunch on OCN) and play it safe and you cant go wrong with either.
