Guide: How to flash a GTX465 to GTX470

post #1 of 191
Thread Starter 
So if your lucky and you snagged a GTX465 with 10chips and you want to flash it to the GTX470 your in the right place.

Warning: I am not responsible if you brick your card.


This is risky you have been warned!

Thanks to ciavto over at Guru3D forums and timAHH right here at OCN.

Things that you need:

-NVIDIA GPU.

-GPU-Z

-NiBiTor

-nvflash

-Bootable floppy disk or Bootable USB


Before you begin to attempt to flash your cards you will need to grab the applications first.

Civato at guru 3d has made a nice package for you:
Quote:
Download the package , it contains: http://www41.zippyshare.com/v/63703260/file.html

-NiBiToR.v5.6 (use the latest)

-nvflash.v5.93.0.1 (use the latest)

-USBimage w7 ( for making a bootable USB, tested with windows7 64bit)

-HP USB Disk Storage Format Tool ( need it to make the bootable USB)
You can grab GPU-Z here

After I downloaded them I created a folder to store them on my desktop for easy access.

Step 1.
First thing we need to do is backup your original BIOS.

Open up GPU-Z and click the little chip next to BIOS Version. Save it to file, I made a folder in Documents called GPU BIOS to save it in. I renamed my BIOS S465.bin The "S" is for stock. That is how I will be refering to the 465 BIOS from now on.

Step 2.
Civato:
Quote:
Open NiBiTor ->
File ->
Open BIOS... ->
Files of type ( Nvidia BIOS Files(.bin)) ->
Load the BIOS that you saved with GPU-Z.
Load S465.bin into Nibitor. Nibitor doesn't recognize 465 BIOS's right now so dont be worried that everything is blank. Save the BIOS as S465.ROM It is very important you save it as a ROM!

Step 3.
Making a bootable flash drive I will be only covering how to make a bootable flash drive as I don't know anyone who has a floppy drive.

1b) Making a bootable USB

First install "HP USB Storage Format Tool"

It's included in the download package.
(USB Flash ready for NVIDIA).

-Connect your USB to your PC.
-Start "HP USB Storage Format Tool"
-Select the USB
-Select FAT32
-Select Quick Format
Quote:
-Mark "Create a DOS startup disk"
-using DOS system files located at
(pick the "USB image w7" file for this, also included in the download package)
-Start.
This will make your usb drive bootable.

Quote:
Rightclick on the file autoexec.bat on the floppy boot disk or USB and select EDIT (if you can't see the file you may need to enable viewing of system files).
For me on Windows 7 x64 I had to go to control panel-> search for "folder"-> click folder options-> go to the view tab-> click show hidden files,folders, and drivers -> uncheck Hide protected operating system files-> click Apply-> click Ok.

Go to your boot drive and you see it a "autoexec.bat" right click it and click edit. Note pad should open up. Add "nvflash -4 -5 -6 S465.ROM" Save it and exit.

Copy nvflash.exe, cwsdpmi.exe , S465.rom onto the USB. The two exe's can be found in nvflash folder wherever you extracted the toolset from.

Make sure S465 is a ROM file now!

Now download a BIOS from a GTX470 you can find some here. OCN has some also.

I renamed that file 470.ROM and that is what I'll be calling it for the rest of the guide.

Step 4.
Reboot your computer and set it so that it boots from the USB stick.

When you boot into nvflash and it prompts you to update your firmware skip that.

After skipped the update and all you have is the dos box with a blinking cursor type in nvflash --eraseeeprom hit enter and select the card you want to flash and wait for it to erase. If you have multiple cards type in the command again and keep on erasing the "eeprom" till all of them are done.

After your done with erasing the "eeprom" its is time to flash your cards with the new BIOS.

Type in nvflash --list hit enter. This will list all your Nvidia GPU's in the system. this was helpful for me so I knew what index's they were.

To proceed with the flash, type in this command nvflash --index=0 -4 -5 -6 470.ROM and hit enter. I have two GTX465's so my first card was index 0 and my second one was index 1. The --list command will tell you the GPU's index location.


After flashing all your 465's turn off your and boot into windows. I had to reinstall my drivers again. If you do after the re-installation open up GPU-Z and see if your cards look like this.

Great guide. Kinda torn between the 465 or 470. 470's have lifetime warranties. 465's dont :-\\

Okay, then copy the autoexec.bat file from "USB image file w7" folder onto the boot drive and then do the edit.

...or just rename .bin to .rom. There is no need to load the file into Nibitor.
