I don't want this to get buried in the GTX680 overclocking thread.
User CrazyNutz on XtremeSystems has posted a BIOS unlocker that works for Kepler-based GPUs and allows greater than stock voltage.

By default it will unlock to 150% Power, Voltage 1.1875v (1.2125v On Boost, only on GK104s), and Fan Range to 30% - 100%.
I tested it myself on my GTX680s this afternoon. At full boost my cards run at 1359MHz on the stock coolers at +150% power, +160 core and +250 memory. Here is a screenshot of it working in Skyrim: http://i.imgur.com/2rWPe.png
Previously my cards were only stable up until around 1290-1300MHz, so this is a noticeable improvement. Also, I am on stock coolers - this will be even better for those of you with water cooling or aftermarket coolers.
You will need a copy of NVFlash, and GPU-Z to dump the original BIOS (make sure you keep a backup of the original BIOS).

- GPU-Z: http://www.techpowerup.com/gpuz/
- KGB (Kepler BIOS Editor): https://www.dropbox.com/s/vrunxuq03vj0m5y/kgb_0.5.zip
Here are the steps to use NVFlash (run it in a cmd window inside of Windows then reboot).
With a single graphics card:
- nvflash --protectoff (turn off BIOS protection)
- nvflash [rom file] (flash BIOS)
With multiple graphics cards:
- nvflash --list (lists graphics cards indexes/IDs you have in the system)
- nvflash --protectoff --index=[ID]
- nvlash --index=[ID] [rom file]
PLEASE BE CAREFUL. You can absolutely brick your card here if you don't know what you are doing.
