and why not just use afterburner to slide your voltages up instead of flashing?

Because with the default BIOS, the maximum voltage you can set is 1.087. With this BIOS, you can set up to 1.212v.

It's extremely simple. All you do is extract the contents of both files in a folder on your C drive. Say nvflash for example. So

1) Create nvflash folder on C drive
2) extract nvflash program files and BIOS rom file into the folder.
3) Using the Windows start button, select run type in CMD then click OK to open command Window.
4) At the command prompt, type CD\nvflash then press enter to change to the nvflash directory.
5) at the command prompt type nvflash -b <filename>.rom to back up your BIOS. <filename> being whatever you want to name it.
6) at the command prompt type nvflash OVEVGA470.rom press enter and follow the prompts.
7) Reboot for flash to take effect.
It's that simple.

If you wish you can use GPU-Z to back up your BIOS skipping step 5. However GPU-Z saves the file as a .bin file instead of the .rom file. Just rename the file with the .rom file extension and it will work fine.

Edit....added BIOS backup directions and reboot.


Good stuff thanks
I just knew about the flashing method using a USB jump drive.

Well damn.  I wish i could get this to work.  I've tried one card at a time, disabling pcie slots, unistalling drivers, etc.  This wouldn't be a bios for a SC card would it?  nvflash lists all 3 of the cards but when it tries to flash it says they're not compatible with the rom.  Anyway, thanks for posting this hemi.  I just wish it would work for me

im fairly certain that this bios is for a SC card, since hemi and me both have sc cards and it worked for both of us.  if you find a bios for the standard card the same method should still apply.

that would be nice if someone could find 470 vanilla bios that gets you up to 1.212mV

would this work with a gtx 275 ftw

i have went from 715 on the core to 740
and the mem from 1260 to 1320 im doing 55c underload
i want to puch for more

what i mean is there a way i can unlock the volts for me

No. Unfortunately with your cards design, the volts are not adjustable with software. You're in the same boat as the 55nm GTX 260, the 275's and the 285's.

Folks if you read the supplied documentation, you'll see there is a flag you can use to bypass the GPU detection which will allow you to flash pretty much any BIOS. The thread is titled Unlocking GTX 470 SC voltage...for a reason. 
Now my suggestion is that is if you are are dead set on AT YOUR OWN RISK  flashing the SC BIOS, is to test your cards thoroughly at SC clocks with your stock voltages. In other words, set your core clock to 625 leave the voltage alone and make sure your card is dead solid. Back up your existing BIOS and remember this is AT YOUR OWN RISK!

Re:Unlocking GTX 470 SC voltage... 2010/08/21 20:26:56 (permalink)
This bios is for a SC version card.  You can flash a vanilla version by using flags in your command line.  I have 3 470 vanillas and was able to flash using the method described above but had to add 4, 5, and 6 before the filename.

ex.
nvflash -4 -5 -6 OVEVGA470.rom

It will warn you that you're about to flash between card versions but just hit y to continue.

And like always, backup your original and Flash at your own risk.  I flashed all 3 of my cards this way and the're working fine.

may have to figure out how to flash the bios on my cards later tonight, have one card that i can run at 890mhz and this would help me break the 900mhz barrier since im voltage limited right now


It's extremely simple. All you do is extract the contents of both files in a folder on your C drive. Say nvflash for example. So

1) Create nvflash folder on C drive
2) extract nvflash program files and BIOS rom file into the folder.
3) Using the Windows start button, select run type in CMD then click OK to open command Window.
4) At the command prompt, type CD\nvflash then press enter to change to the nvflash directory.
5) at the command prompt type nvflash -b <filename>.rom to back up your BIOS. <filename> being whatever you want to name it.
6) at the command prompt type nvflash OVEVGA470.rom press enter and follow the prompts.
7) Reboot for flash to take effect.
It's that simple.

If you wish you can use GPU-Z to back up your BIOS skipping step 5. However GPU-Z saves the file as a .bin file instead of the .rom file. Just rename the file with the .rom file extension and it will work fine.

Edit....added BIOS backup directions and reboot.

 
This is exactly what I needed.  I have not made up my mind yet, but having this here helps.  Well done HeavyHemi.

since you have a E760 could just disable all but pci slot #1 and try it. and sorry d1esel knocked you down a rank on hw bot for tri sli 470's


Yeah my poor old Corsair HX1000 won't let me go over 830 on the GPU's and 4.5 on the CPU at the same time...

 
So does that mean my dell psu is better then your old one? :p considering i bumped up my clocks on my card after everyone on the thread i posted told me to lower it >->

The Corsair HX1000 is two separate 500 watt PSU's in one enclosure...it isn't surprising that running two OC'd GTX 470's on basically 500 watts might be an issue. As far as bumping your clocks up on a sub-par PSU, it's your money.

Just got this working, thanks.
 
 
But thanks I just realized that that my psu starts to crash when I get the cpu to 4.3 on heavily oc the cards.  Guess its time to save for a bigger psu.

The information in OP is originally mine and is hosted on my file server. I would like at least some credit for the work I put into making the flashing process so easy.

Sorry buddy. I don't know who you are nor have I read your material. Do us all a favor and edit your post so you're not 'yelling'. The link to the BIOS file I obtained from a different thread.

Yes hotlinking will result in a corrupted file download. The referrer must be overclock.net
 
Back to studying... I'll put the files back up later this week.

I'm glad I was able to talk some sense into you. Purposely bricking cards is a crime IMO. So, I'll cite that the BIOS is your file and link to the page where the BIOS is posted on OC.net. Problem solved.

Is no one going to mention that you can pull your OWN bios using NibiTor, under "Tools" go to "Fermi Voltages" and use the top box to make the max voltage what ever you want?  Then you know it's YOUR BIOS, and can flash easily. :)

Wow, talk about getting his panties in a bunch. I would advise people just to steer clear of this all together at this point if that's how he's going to act.

I think we have it sorted out. I changed the first post to credit him for the BIOS file and linked to the thread on OC.net...which BTW doesn't contain what you would call a simple concise guide as I posted with the help of others in this thread. I think the mods and I are satisfied with the outcome.

I could not get my Vanilla 470 to work with that bios (i downloaded it from the original site; seems older april 09 date and a different 470 type than mine).  It would reboot and recognize only a standard vga adaptor.  Good thing i made the backup with GPUz.  As someone mentioned above.  People should be using a bios that works - and that is their OWN.
 
download xtremetuner HD and take 3 the nvflash files (these will run in windows7 64bit cmd.exe evironment so no need for a bootdisk unlike other versions i found on the internet).  Can delete the xtremetuner after those files are taken.
 
make 2 backups of your bios. 2nd one is to be modded with the next program.  
  nvflash -b 1.rom
nvflash -b 2.rom
Download a program called nibitor 5.7.  This allows 2.rom to be adjusted.  Open the 2.rom.  fermi voltage control - increase limit to the max 1.2.
 
Save the bios, 2.rom.  use nvflash to install that bios without the need to use Force flash options.
nvflash 2.rom
 
Reboot.  I dont think anyone should have a problem with this method.
 
Download nvidia inspector.  This program will allow you to increase the voltage beyond 1087.  Push your core shader and mem clocks with afterburner or precision higher than before.
