SLI Different Kepler Cards

[_distorted]

Hi.
I read it once somewhere, I don't know if it's legit or not.
I currently have a EVGA GTX 660 Ti FTW Signature 2 card.

And I was wondering, is it possible to SLI a Kepler card with another Kepler card, e.g: GTX 660 Ti FTW Sig2 + GTX 690 or GTX770?

I really don't remember how I stumbled upon that article, but it mentioned that Kepler cards can be SLIed no matter what model, ram, memory they have.

Is that possible?

No. SLI must use the same kind of card. They can be from different manufacturers or have different amounts of VRAM (the one with larger VRAM acts as if it had the same amount as the lesser) or different clockrates (I believe that the faster one also steps down to the lesser card, but don't quote me on that one).

The article was probably referring to Crossfire, or the article was incorrectly applying Crossfire's inter-model capabilities with SLI.

There was a guy who reckoned he had rewrote the drivers so that it was possible to SLi any two Nvidia cards but I've no idea if it actually worked or not.

Awesome.

Thanks for the clarification guys, wanted to know for sure before I spend that extra for the upgrade.
Will definitely go for another EVGA GTX660 then for SLI.

Cheers.
