which 680?
Only original 680 lightning ln2 bios has any form of half-decent overvoltage capability with afterburner 2.2.3

You'd need to use a specific Lightning bios along with the version of afterburner mentioned above.
Failing that you need to look into using the artmoney hack, though be careful, one wrong press of a button and you could send 1.8v through the core and kill it.

I went for the latest one off the MSI website but either way should it not be able to go above 1.175V? I have adjusted it on afterburner +100mv (0.1V) which made no difference, so shouldnt this increase it? Doesnt the lightning bios increase the standard voltage (I read that somewhere but not 100% sure its right) hence the higher clock?

Nvidia do not allow overvoltage.
-The features of the voltage controller are disabled in newer versions of afterburner.
-The features of the voltage controller are disabled by BIOS revisions

As pointed out you need the VERY FIRST vbios, NOT the latest. You will not find the first bios hosted by MSI as its outlawed by Nvidia (as optima has pointed out).
Despite it saying +100mv is available it is not. +100mv should take it to 1.275v not 1.176v.
Google '680 Lightning Artmoney' though if you're not 100% sure and confident in what you're doing, leave it well alone.

I get 1.25mV with the locked LN2 bios for the 680 lightning from the MSI site, this is with 100+ voltage in afterburner, make sure you set the bios switch to LN2 mode and flash it with the lightning LN2 bios, use MSI afterburner beta 11 for the 680/770 lightning.
To get true unlocked voltage in excess of 1.3mV you will need the lightning unlocked bios that came out with the first load of cards and before nvidia put their foot down and made MSI lock voltage control, that bios is linked below along with an updated bios that is unlocked as well.

Just out of curiosity what type of overclock are you getting at stock 1.175v?
My experience with a Lightning GTX680 overclocking was that there was very little difference in performance (less than 3%) between ~1300 and ~1370 core clock as long as your VRAM was getting 7GHz +.
