Make sure that the position on your HD 6950’s BIOS switch is set to the 1 position (the default position on most cards).Step 2:Download ATI Winflash
(ATI Winflash is a program for Windows that allows the user to back up, load, and re-flash graphics card BIOS on AMD/ATI cards.)
And then the Radeon HD 6970 BIOS
(The Sapphire 6970 BIOS are recommended because they function with cards from any manufacturer).
Just in case something goes wrong, back up your HD 6950 BIOS by running ATI Winflash and clicking "Save".
Open up ATI Winflash, then hit "Load Image" and select the HD 6970 BIOS that we are going to use. Make sure to keep Winflash open, do not just press "OK".
Hit the "Program" button in Winflash to begin the flashing process which will reboot your computer.
Check to see if the flashing process worked using GPU-Z
(at least version 0.5.0 or it won’t display correct specs). If the process worked correctly, it will display a shader count of 1536 instead of 1408.
In case of an error (which is what happened to me), such as an ID mismatch or "Could not erase ROM"
, you can try this fix:
- Unpack the Winflash download onto your desktop in a folder called "winflash"
- Save the 6970 BIOS in your Winflash folder and name it "unlock.bin
- Click on your Start menu
- Type "cmd"
- Right click the entry and select "Run as Administrator"
- A black Windows Command Prompt window will open
- Type "cd %USERPROFILE%\desktop\winflash" and press enter
- Type "atiwinflash -unlockrom 0" and press enter. The "0" refers to the first adapter. If you have multiple cards, physically remove all but the one you want to flash
from your computer
- Type "atiwinflash -f -p 0 unlock.bin"
and press enter. It should complete the flashing process with a message saying something with "verified".
However, this particular fix did not work for me, and I was forced to use the automatic method to complete the process. We detail this method on the next page...
