PLEASE NOTE THAT I HAVE ONLY TRIED THIS ON MY XFX 6950 2GB
The very first thing that i did in the quest to unlock the shaders in my 6950 was to go and download the newest version of GPU-Z from here.
The next step is to open GPU-Z. It should look like this (if you opted for the ROG version)

The next step is to save the current BIOS version to disk, to do this simply click on the little chip with an arrow on it.

By doing this you are making a copy of the BIOS that is currently on your card. We will be using this later on so go create a folder on your desktop called winflash (we will be using this later, dont worry).
The next step is to go and download RBE (radeon BIOS editor), you can find it here. You might as well take the opportunity now to download ATIwinflash which can be found here.
When you have them both downloaded, extract atiwinflash to that winflash folder that you made on your desktop, now forget about winflash for a few mins while we do the shader unlock mod to the BIOS that you saved earlier.
To modify the BIOS we will be using RBE. The first step within RBE is to load the BIOS that you saved earlier.

When you have loaded the BIOS that you saved in the winflash folder on your desktop click on the additional features tab.

Once you are in the additional features tab you should see an option to change the shader count from 6950 to 6970. You will want to click on the 6970 shader count option. Once you have selected 6970 option, click on the save BIOS option at the bottom

You will want to save the file in the winflash folder that you made earlier, name the file something like bios.rom, just to make it easier for yourself later on.
Now you should be ready to flash the new BIOS.
To flash the newly modded BIOS you will need to go into Command Propmt (as an administrator to avoid any problems). When in Command Promt you will need to browse to the winflash folder on your desktop by typing "cd %USERPROFILE%\\desktop\\winflash". It should look something like this except with your user name instead of mine.

The next thing that you will need to type into Command Prompt is this "atiwinflash -unlockrom 0", doing this will unlock the ROM on the first adapter.
The next thing to type is "atiwinflash -f -p 0 bios.rom", if all goes well after typing that in then a box should popup that has the word verified some where in it, when you click OK for that prompt it will tell you that you have to restart you computer. When you are back into windows you can check to see if you have successfully unlocked the shaders by opening GPU-Z again, you will know it has unlocked when it says 1536 shaders as opposed to the 1408 you had before!

First tutorial, so go easy!
