Do at your own risk! I am NOT responsible if anything goes wrong! Although nothing should.
All Credit for creating this mod goes to Saltius and Mavke over at mkvtech for finding and releasing this mod to the public. A BIG thank you to CrazyNutz for creating KGB and V3DT for creating his online 600 Series Firmware Modifier!

Please do not PM me on how to do this, there are guides here for a reason, and all I will do is tell you to read the OP.

It is actually 1.23v confirmed on volt meters.


I need to update this one, my score is much higher now. From just going over to the 306 drivers I gained .2 fps in heaven. and I was able to clock some more.

Mod your own bios!
Option #1: KGB Difficulty: Moderate
Thank you to [email protected] for making this!

KGB - Kepler BIOS Editor/Unlocker
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!!!

Option #2: V3DT online bios editor Difficulty: Easy
http://www.v3dt.com/nvidia/600/ < the site, simply follow the on screen instructions and flash with firestorm or Nvflash.
The thread:
http://www.overclock.net/t/1340182/online-600-series-firmware-modifier-version-0-6/50#post_18895955

Things to do before the flash:
  • Reset your overclocked settings in all programs you use.
  • Reinstall NV drivers with clean install(not necessary but some people have had to)
  • For sli setups use the following commands
    For GPU1: nvflash --index=0 -4 -5 -6 nameofurbios.rom

    For GPU2: nvflash --index=1 -4 -5 -6 nameofurbios2.rom

Hello, this is General123 and I have made this quick and easy batch file to help people flash their cards faster. All you have to do is make sure your modified .rom is named
"X.rom" and in the same folder as the other files provided. Simply click the "RUN" file and a command windows will pop up running two commands, the first "Nvflash --protectoff", this is to insure NVFLASH has the ability to right to the entire card. The next command is "Nvflash -4 -5 -6 X.rom" this will flash the modified bios, or any bios with the name "X.rom" to the card. Enjoy! I hope this makes life easier when flashing.

My personal favorite flash guide
http://www.techpowerup.com/downloads/2133/NVFlash_5.118_for_Windows.html
Download that and extract it into a folder, in that folder also make sure you have your modded bios, for reference I will be calling it "X.rom" you can rename it to that to keep this more simple..

Shift+ Right click in the folder and click "open command window in here" then type the following commands in order.

Nvflash --protectoff

Nvflash -4 -5 -6 X.rom

That should be all it should go as planned and reboot and you should be modded.

This is a much better option than the BIOS's listed on the front page, as the GPU retains down-clocking to save power. Also, fan speed is unlocked up to 100% and the card hasn't gotten above 64C. Nvidia should have let us do this all along.
For those looking to try it, here is a mini guide extracted from a bunch of others including the front page by General123, for what I feel is the easiest way to perform the BIOS edit.
1.) Download the BIOS Editor.
2.) Use GPUZ to extract your VGA bios, and make a copy into the KGB folder, and a backup elsewhere.
3.) Hold Shift + Right Click in the KGB folder.
4.) Select "Open Command Window Here"
5.) In the command promp, type "kgb.exe [Your Saved Bios Name].rom unlock"
6.) Download FireStorm and install it. (The install screens are in another language, just keep clicking where the "Yes/Accept" button normally is.
7.) Run Firestorm, click on the "BIOS" button, locate your modded bios that is in the KGB folder, and flash it.
8.) Restart, enjoy!

Now boot from the flash drive.

Run the commands below, of course replace the bios name with your own.

Questions and answers

Is this risky?
There is a certain degree of risk in everything, but really not very much.

Why should I mod my bios?
Because you gain more performance! Duh
smile.gif

Does anyone know if it is safe to be running at 1.212V on boost as an everyday overclock? How much would this decrease lifespan?
It's safe enough. I have been running it since thread date and my card is still chugging along just fine. As for life span no one can really say because the card has not been out long enough to say.

Can I use a 670 FTW bios on my reference 670(applies to any other question like this, not just reference cards and FTW bios')
Of course you can, but there is no point in doing so. Modding your own bios is easy, and is just a better idea.
Will be adding more latter.

That's pretty cool man! Heaven maxed out is annoying I keep crashing at the like second to last stage >_< and the thing is the benchmark is so long lol.
Ill update this post after this run it should be solid. My old max core clock in heaven was only 1283, lets see what we get (Hint i've been getting a 20-60mhz increase in games

He had nothing better to do than to run his mouth and tell me how stupid I was and now he is eating crow so I dont expect he will pop into this thread anytime soon.

I dispise folks who assume we have nothing better to do than to make crap up or lie about our GPU temps. Anyway, nice result and congrats!

Okay I got mad about it crashing over and over in stage 18ish so I just lowered the clocks alot to 1304, which is still a 21mhz increase I can get more for sure, but I want to try out different benchmarks(And break 11k in 3dmark11
biggrin.gif
)

Not sure if this is good or bad TBH dont see many people run it maxed out.

Yeah the average is about 40-50mhz more on the core after the flash and that score is great for 1304 on the core.
