    How to enable additional shaders on Radeon HD 6950

    GPUz 0.5.5 reports it as AMD Radeon HD6900 Series with GPU Antilles. Device Manager reports the Hardware ID as VEN_1002 & DEV_671D, which I believe is the hardware ID for a 6990. I'm pretty sure the card only has a single GPU on it though. Other people with the Dirt3 edition 6950 seem to have...

    How to enable additional shaders on Radeon HD 6950

    BIOS switch is in position furthest away from crossfire connector. Fairly sure it flashed successfully as winflash verified the flash and asked to reboot. Edit: After a little more digging it appears this is a problem on cards which identify as Antilles GPU. Any further information on why this...

    How to enable additional shaders on Radeon HD 6950

    I've got a Sapphire 2gb Dirt3 edition. RBE doesn't allow the Unlock 6950 > 6970 option to be selected as it is greyed out. Used GPU-Z to dump the BIOS and the unlock script. Seems to flash ok using atiwinflash, says verified and prompts to reboot. Does this indicate that the BIOS isn't hardware...

    How to enable additional shaders on Radeon HD 6950

    Hi fufnk, I have the same card as you and am also unable to unlock the shaders. My understanding of the 6990 is that the Antilles GPU is pretty much the exact same as the Cayman GPU, except there are two chips on the card. If you look at our 6950's, there is only the one GPU. There's no way to...

    How to enable additional shaders on Radeon HD 6950

    In addition to my last post, I tried the batfile script on the BIOS from my Sapphire 2gb Dirt3 edition, and flashed with the BIOS that the script created. The flash was successful as far as I can tell, but the number of shaders remains at 1408. I have uploaded the original BIOS.

    How to enable additional shaders on Radeon HD 6950

    Just bought a Sapphire 6950 Dirt 3 2gb which I was planning to unlock the shaders on. I've noticed that GPU-Z is reporting that the GPU is Antilles and that the device id is 671D. Is that normal? Can I still go ahead and unlock the shaders? Edit: Just realised I can't unlock the shaders using...
