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!
Things to do before the flash:
The all in one backup tool
My personal favorite flash guide
Flash guide with KGB
How to make a bootable USB
Flash guide with DOS
Questions and answers
Is this risky?
Why should I mod my bios?
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?
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')
Will be adding more latter.

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

My personal favorite flash guide

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.

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
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.
