Once the clock speeds are adjusted to match the HD 6970, the card effectively performs just as well as a full blown Radeon HD 6970. We can see that enabling the shaders without any clock increases improves performance. Save the BIOS from your card, load it into RBE, enable the shader unlock option on the last tab, then flash that modified BIOS to the card instead of the one downloaded from this page.įeel free to post in the discussion thread for this article if you need additional assistance with the flashing process. If you have a custom design or 1 GB card, then use RBE to modify your existing BIOS.

Update 2: Above method is only for 2 GB HD 6950 reference design cards.

You can download it here, please report success or any issues with the scripts in the comments for this article. Update: I have uploaded a pack of all the files required together with some batch files to ease the process for less experienced users. 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.

Check stability in Windows desktop applications and games.

The "Testing" section of this article has more data on that.

To ensure maximized performance open Catalyst Control Center, go to the Overdrive tab and set the PowerTune slider to the +20% setting.

If you see a shader count of 1600, your GPU-Z version is outdated.

Make sure you use version 0.5.0 or newer, the official 0.4.9 version does not support HD 6900 Series properly.

Check the shader count using GPU-Z, it should show 1536.

Let the flashing process complete and reboot your system.

Load the HD 6970 BIOS into Winflash by clicking Load Image, followed by Program.

Run ATI Winflash, click Save to save your BIOS, so you have a backup in case something goes wrong.

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).

The Sapphire one I linked to will work on all reference design cards from any vendor.

Grab ATI Winflash from here (32 & 64-bit).

I will describe the method for flashing from within Windows, which is safe enough on these cards because of the dual BIOS feature that enables easy recovery. You could use the ASUS BIOS which comes with higher clocks & Overdrive limits and enables voltage changes via SmartDoctor, or stick with one of the reference BIOSes in case you are afraid the clocks might be too high. Any of these BIOSes will work on any reference design HD 6950 card.

You can find a few in our VGA BIOS collection. Unlocking the additional shaders is done by flashing the card with a HD 6970 BIOS. Usually production cards come with the shader count configured in the fuses, so that it can not be changed.Īpparently currently shipping Radeon HD 6950 cards from all manufacturers - which actually are all the same card with different sticker - have their shaders locked via the BIOS method, so we can exploit it easily. This method is mostly used to create engineering samples or reviewer cards that match the target specifications. The second mechanism is the one we are interested in, AMD can configure the VGA BIOS in a way that it disables extra shaders, in addition to the ones disabled via the on-die fuses. The first one relies on fuses inside the GPU, or on the substrate - a mechanism similar to Intel's multiplier locking. When unlocked, these deactivated units become active, resulting in a substantial performance increase.ĪMD has two methods of locking the shader count on all of their recent GPUs. The picture above shows the disabled HD 6950 shaders in red. Please Digg Reddit this story to spread the word. The HD 6970 has nothing that can be unlocked. This article is to unlock the Radeon HD 6950. Creating new SKUs from the same silicon by locking features has been common practice in the industry since at least the Radeon 9500 in 2002. The model variant a GPU chip becomes is decided after the die is produced, at some point before it is put on the card.

Just like on all other similar products, AMD's two Cayman variants, called Cayman Pro and Cayman XT, are based on the exact same GPU silicon. Both cards are based on AMD's new Cayman core which is their first graphics processor to use a VLIW4 shader configuration. IntroductionA few weeks ago AMD released the Radeon HD 6970 and Radeon HD 6950.
