Here you go mate. ;)

"Step 1) Download ATI Winflash:http://www.techpowerup.com/downloads/1919/ATI_Winflash_2.0.1.13.html (The newest version has been reported to not work).
2) Install winflash in the root directory (i.e. C:\winflash)
3) Download the script to modify the bios and extract it: www.techpowerup.com/wizzard/Mod_BIOS_HD_6950.zip
4) If you have a BIOS switch, set it to the 1 position (TWIN FROZR Will not have a BIOS SWITCH)
5) Run ATI Winflash, click "Save" to save your BIOS, be sure to make a copy of this and save it some where safe in case some thing goes wrong.
6) Make a copy of the saved BIOS and rename the copy to "original.bin"
6.a) If you cannot see the file extensions, you need to open the Folder Options in the control panel and uncheck the option "Hide extensions for known file types"
7) Copy the "original.bin" file to the script folder "Mod_BIOS_HD_6950"
8) Execute the "run.bat" batch file
9) Look in the folder "Mod_BIOS_HD_6950" and copy the file "modded.bin" to the folder you installed ATI Winflash in (C:\winflash)
10) Open up the command prompt (Start->All Programs->Accessories) you may have to right click and run as adminstrator
11) Change to the ATI Winflash directory with the command "cd C:\winflash" or what ever directory you saved it in
12) Type "atiwinflash -unlockrom 0" (the "0" stands for the first PCIe card installed, "1" will work for the 2nd card)
13) Type "atiwinflash -f -p 0 modded.bin" (the "0" stands for the first PCIe card installed, "1" will work for the 2nd card)
WARNING: do not turn off your computer until step 13 is completely finished.
You should have successfully installed the modified BIOS. You will see a window pop up to say it was verified and ask you to reboot if everything went as planned.
14) To verify that you succeeded in unlocking the shaders, use GPU-Z and look to see that you have 1536 Unified shaders.

If your system becomes unstable after you reboot, you'll have to reflash the original saved BIOS back onto the card following steps 10-13 and using the "original.bin" BIOS in place of "modded.bin". "
 
Hi would this work on a HIS ICEQ X Plus 6950 is it worth a try?

It should work on most cards as all youre doing is altering the default bios to unlock the shaders. However obviously there is a risk. You need to decide if its worth the risk.

If something goes wrong you have the default bios to load back on and that should save you. I didnt try flashing the bios, too risky. The shader unlock worked on both my 6950's though.
 
Thanks for this Matt, I'm picking the sapphire 6950 2gb up on the way home from work. £225 from local shop, there's a switch on them which apparently unlocks the shaders automatically sometimes if not I'll try this flash.

Np dude. Spreading the love. Banks asked me about it on battlelog. He tried with your card, the bios switch didnt work though so good luck on that one. :)
 
Erm think ive fully broken it, i get bsod when i turn it on after the loading windows regardless of the switch position! It wont even boot into safe mode! Uh oh ... Any ideas? Have i bricked it, even though i was using the switch on the secondary bios section?

I dont understand any of that =o( ive ****ed it, i dont understand why the safe bios aint working? Think im gonna have to send it back

I dont have experience of the bios switch, as my cards dont have them. What position was the switch in when you did the shader unlock?

According to that vid you flick it to the right and that way you still have the original bios on the left. Infact in this video he shows you how he did it, he has the same card as you right?
