KGB (Kepler Golden BIOS) Is an Nvidia Kepler BIOS Editor/Unlocker program I have written. Enjoy
KGB supports: GTX690, GTX680, GTX670, GTX660Ti, GTX660OEM and GTX660.
Instructions: KGB is a console application, you must use it from a command prompt in windows. Start menu then type cmd, then cd to the folder containing kgb.
You will need to extract your bios from your card with this version of GPU-Z http://www.techpowerup.com/forums/at...2&d=1344772659
When you are done modding your bios you will need to flash it back to your card with nvflash.
Usage Example 1: kgb.exe your_bios.rom
This will display info from the bios.
Usage Example 2: kgb.exe your_bios.rom unlock
This will unlock your BIOS. Make sure you have a backup of your original BIOS file!!!!!!!!!!!!!!!!!!!
By default it will unlock to 150% Power, Voltage 1.1875v (1.2125v On Boost, only on GK104?), and Fan Range to 30% - 100% (You can now define these values in the kgb.cfg file)
NOTICE: When you unlock the bios your card WILL boost higher, It may boost past stable. If you have any overclocks set then it WILL very likely boost past stable.
Remove your overclock settings (from precision, afterburner, etc..) then try again. If it's still unstable you may have to underclock the base a bit.
WARNING: KGB works on all the bios files I have so far. However that's not to say it will work on yours. Make sure to look at the output of KGB after you unlock,
If something looks fishy do not flash it. If something goes wrong I take no responsibility. Use at your own risk!!!
Test version of KGB for titan. Only fan, and power supported for now:
-Added support for more bioses
-Added config option to change the max boost frequency.
-Added EXPERIMENTAL option to preserve the original checksum.
-Added fixes for some bios that KGB was not playing nice with.
