GTX 780 flashing bios

[murah]

Flashing is easy really use Nvflash and make sure you have a back up of your original bios

things to change:

Power target (True on 670's don't know about 780s!)
Voltage (If it holds true to kepler the max will be 1.21v might show up as 1.23v in evga/msi)
and thats it really , I wouldn't bother flashing a bios to your card that didn't originally come with your card only use your existing one and modify that

this is the guide for the 600 series cards but it should hold true for the 780 still

I used Nvflash , kepler bios tweaker(KGB) but you might want to check if 780s are compatible and GPU-z to back up my bios

in kepler bios tweaker (KGB) just edit the text file with your desired power target and voltage, you can specify a max boost but I wouldn't bother

then use Nvflash "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 it, reboot and you should be modded."

Can I use a 780 FTWbios on my reference 780(applies to any other question like this, not just reference cards and FTW bios')
A. Of course you can, but there is no point in doing so. Modding your own bios is easy, and is just a better idea.

in my personal experience I have the best results increasing the power target only, but say I have hit a wall at 1287mhz but my OCD makes me want a nice round 1300mhz then typically I would bump the voltage by a jump (refer to KGB text file for legit volts) and hey presto I'm where I want to be.

Edit: Forget most of what I said if you find out KGB doesn't mod 780 bio's and read the guides on here ^ ^ ^ I don't want you to have a bricked card as I'm not entirely sure that KGB works with the 780s.

Thanks for the info, i'll have a good read through.

Haven't you done it yet?

 

[*Rich*]

Haha, no second card isn't here yet, got to wait for that to use the bios from it.

Then who knows what's next

 

[steveoz]

Ahh fair enough

you cant flash any reference bios to non reference card its not that simple, the PCB will be modified and in most cases very different, Evga 780 SC is not the same as the 780 Classified for example, these are two completely different PCB's however your Evga 780 SC is a reference PCB so should be fine to flash the other with the same bios, just make sure you back up the original bios in case it dont work as intended or for warranty reasons

Thank you, yeah i read about it now, hopefully all will go ok. And warranty is already gone

Ok, so i gave it a go........and, it worked. I now have two Superclocked 780's.

At first it didn't work, it kept flashing up with a message so fast i couldn't read it. After numerous attempts, i took the other card out, and then first try it worked.

Both cards now working together and clock speeds all the same without having to start Precision X everytime.

Thanks for your help, without you i wouldn't have tried it Oh and here's why the warranty is gone on the first card

I took it apart and modified it to the colours i wanted Need to do the other one now.
