Transform your HD 6950 to HD 6970 with a bios flash tools

This is the present of the day from Santa , if you have a AMD Radeon HD 6950 , this is a nice news for you cause now you can unlock the HD 6950 to reach the power of the flagship HD 6970 with a simple BIOS update according to a Wizzard from Techpowerup.

Look like AMD leave The Radeon HD 6950 unlocked because it can switch from 1408 to 1536 shaders and even reching the HD 6970 clocks speed , this BIOS upgrade can be applied on all available HD 6950 on the market until now , also AMD made it easier and safer with the dual-BIOS feature on its HD 6900 series cards and if something goes wrong you can always go for the factory protected BIOS.


The Download & instructions via TechPowerup!
  1. Grab ATI Winflash from here (32 & 64-bit).
  2. Download HD 6970 BIOS. The Sapphire one I linked to will work on all reference design cards from any vendor.
  3. Make sure the BIOS switch on the card is set to the 1 position (pictured further down if you don't know where it is).
  4. Run ATI Winflash, click Save to save your BIOS, so you have a backup in case something goes wrong.
  5. Load the HD 6970 BIOS into Winflash by clicking Load Image, followed by Program.
  6. Let the flashing process complete and reboot your system.
  7. Check the shader count using GPU-Z, it should show 1536. Make sure you use the linked version of GPU-Z, the official 0.4.9 version does not support HD 6900 Series properly. If you see a shader count of 1600, your GPU-Z version is outdated and you should get the one from the link here.
  8. To ensure maximized performance open Catalyst Control Center, go to the Overdrive tab and set the PowerTune slider to the +20% setting. The "Testing" section of this article has more data on that.
  9. Check stability in Windows desktop applications and games.
If you get an error like ID mismatch or Could not erase ROM, then you'll have to do some extra work in a Windows command prompt (or DOS): Run atiwinflash -unlockrom 0 followed by atiwinflash -f -p 0 bios.bin where bios.bin is the path and filename of the HD 6970 BIOS you downloaded.
