  • @der8auer

    Finally, thank you very much.

    Works great on My PowerColor RX 460 4GB Red Dragon.

  • Nikos


    Unfortunately this one didn’t work on my Red Dragon RX 460 4GB V2 videocard. Additional SP were not unlocked. Furthermore I got checkered image after installing the recommended driver version. Eventually I reverted to my original BIOS.

    I suspect the problem is this is the V2 Red Dragon 4GB card. You can find its original BIOS here:

    Can you please try modding it?

  • Toraz

    Please do bios for this video card

  • Jeeme

    (update) I Already Tried 4 times, there is no problem when flashing and mod driver but no change at all during check in GPUZ. Sorry for my english

  • jered

    I did something wrong in the flash process and now windows is giving me error 43 and wont use the card 😕 any ideas or can someone walk me through how to reset the bios?

  • Danny

    Hey everyone!
    So i just tried this on my card (Powercolor RX 460 4gb) and although the unlock worked and gave me more umph windows gave me the (code 43) error and forced the simple graphic driver on me rendering the card pretty much useless!
    If you were like me and forgot to backup your bios before flashing and ran into this issue then fear not!
    After many hours and rages i finally figured it out and fixed it (Or should i say reverted it back to stock) so i uploaded the folder you’d need and you will recognise the files since they are the same files used to flash it in the first place HOWEVER the bios file is different and is the original bios despite the files name, Just follow the steps as you did to flash the card in the first place and you will back up and running in no time!
    Hope this helps 🙂

    I’ve spent three hours, but now I know where the problem is. AMD has blocked the ability to use this BIOS version in new drivers. Use Crimson version 16.11.5 or below. The video card can then be defined as a “Standard VGA graphics Adapter”, In this case, install the driver manually from the Crimson folder.

  • Peter

    Can confirm that this worked without a hitch. Solid. Confirmed so long as you use the correct video card version – double fans.

  • Perneta

    Windows detected an error, didn´t work with Radeon Crimson 17.5.2 Beta driver.

  • DefiantMiner

    The newer drivers check the signatures again. You will need to use 16.11.5 or older, or patch/resign after manually updating the driver in device manager. There is a “pixel patch with signature” utility that does the trick. Update BIOS, re-load dirver, patch, reboot, done. Use GPU-Z to check shader count.

    Get it here:

    As for this BIOS unlock – I just tried it on a Power Color 460 4GB (two fan) unit and IT DIDN’T WORK. No bricking…just no extra processors. I wish someone would actually tell us HOW to configure the unlock…not just provide bogus BIOS files. I got the Sapphire cards unlocked, but not this one. I even tried using a modified Sapphire file on the PowerColor…no help.

    Did not work on my Power Color RX460 Red Dragon 4GB. Had odd screen artifacts, TechPowerUp GPU-Z reported 1024 shades but Claymore reported that it could not find the GPU.

  • axper

    Working only with Crimson 16.11.5

  • wondering if this will work on game power power color rx 460 4gb ( dual fan). I dont have windows, just running ethos distro, anyway to install the bios mod ?

  • Jedi

    Hi, I have successfully modded PowerColorRX460RedDragonV2.4096.160816 to 1024!

    160816 is BIOS version

    As there was no modded BIOS for this card I analyzed different modded/unmodded BIOSes.

    How to mod:
    **ATTENTION** Do it on your own risk!! For me it worked fine 😉

    save original BIOS with ATI Flash
    Open in HEX editor the BIOS file.

    There are 2 different changes which are needed:

    on 00000021 increase HEX (in my case CE to CF)
    Search for Pattern: E0 5B 7A 14 00 6F 22 ** 22 3D 26 DF 26

    The ** if by default: 70 -> change this to 6F

    Save BIOS and flash it.

    Install latest crimson 17.1.1, do not reboot. Run ATI Patcher.

    Have Fun!

    Thanks TheBauer for his modded BIOSes, he has given me the intention to diff different BIOSes.

  • Jedi

    btw. in my opinion this method could/will work with (nearly) all existing RX 460. Important is: BIOS version should be the same! – That is why for all RX 460 card owners, who have problems after flashing, their BIOS version differs to the modded version they wanted to flash – which is on the main page here.

  • Rubens

    consegui fazer a instalação dos driver 16.11.5 mais primeiro através do Regedit lipei tudo da amd depois instalei e agora estou com 1024 shaders e 64 mtus e o melhor que agora a gpu foi reconhecida esta rodando 100%da capacidade do chip, 3 horas quebrando a cabeça como a amd complica!!!

    • João Carlos

      Rubens desculpa encher o saco eu to com um medo de desbloquear a bios da RX 460 teria como você me dá umas dicas pois tenho medo de não funcionar obrigado pela atenção desculpa te incomodar.

  • Gledison Duarte

    Worked on AXRX 460 4GBD5-DHV2/OC, but only get arround 5% on 3D Mark and 3% on Superposition Benchmark, same on the games, but a little instable. Also increased the temps by arround 5~8ºc.

    Tested with16.11.5 and with 18.9.1 using atikmdag 1.4.6. 18.9.1 gives better perfomance.


    Note: the AtiFlash that comes with the pack doesn’t work on last Win10 upgrade, need to manually download the new version (284), works fine after. Don’t forget to do a backup.
