It's only misinformation if it doesn't apply to you. Which it probably doesn't. Or the OP, for that matter. But who knows for sure? I don't have any experience with that particular card. So I don't know what works or doesn't. Doesn't sound like you do either.
As a matter a fact the 680 I had was a Zotac 2GB reference model, I can upload a moded bios I still have kept as a backup. So YES, I can speak about OP's card.
I must of struck a nerve in you and offended you with my Signature. Well too bad. By the way thanks for the thread necro. I've been seeing numerous people kill all kinds of cards doing bios mods which don't fix anything. You don't like what I have to say? There's the door.
How about you use that door - you have contributed ZERO - that's absolutely nothing constructive. Fear mongering that's all it is and by someone that has no concrete information on the subject and even less knowledge. Seriously dude, what a crap post - actually if I could give you the shittiest post award for the dumbest post I've read on forums thus far this year(probably could even include few month from last years as well) - you deserve it. So here it's all yours... tada!! (giving shitty post award)
For all others interested - the point of modded bioses is:
A) greater performance (major gains to be had)
B) Adjusting fan profile (some like it quiet, some like it cool)
C) Putting it all together and not having to use MSI afterburner at all
Successes don't mean there are not failures, I too have flashed probably hundreds and modded many of them myself, it does not change the fact that the quantity of new members that join do so because they have bricked cards through flashing is bigggg.
The bricking is a result of:
-wrong bios for the wrong board 99.9% of the time
It's impossible to adjust the voltage to have the card fry on boot. Unbricking a card is super easy as well, everyone these days has a in igpu - boot with it and flash the backed up bios.
Further more - cards dying from moded bioses are a result of weak vrm(most of the time) and poor cooling. That is why it is important to read up on the particular cards.
However with KEPLER cards - Nvidia tightened the max voltage soo much that a soft mod can only unlock trivial amounts of extra voltage in most cases. FERMI was a different story, OP was asking about a Kepler card.
