asr1981 Posted January 22, 2017 Share Posted January 22, 2017 I was gifted a radeon 6670 yesterday and I would like to install that card and take the one I'm using out. Right now I'm using a 5450. I'm using El Capitan right now and it's running perfect but I would like to try to use my new card. What would be the best way to go about it? I was wondering what I need to change. I know I need to replace the related kexts and rebuild the cache, are there anything else that I need to change or modify? I'm making a backup of everything just in case I have trouble and need to rollback to a working system. Link to comment Share on other sites More sharing options...
Administrators Hervé Posted January 22, 2017 Administrators Share Posted January 22, 2017 You take out the old card, plug the new one in and reboot without cache. If the new card is supported, it'll work OOB or after any necessary tuning (DSDT dGPU injection or patch adjustments, AMD FB patching, etc.).

asr1981 Posted January 22, 2017 Author Share Posted January 22, 2017 Thanks, I'll go ahead and swap cards and reboot without cache and see what happens. Link to comment Share on other sites More sharing options...
asr1981 Posted January 22, 2017 Author Share Posted January 22, 2017 Thank you so much! Swapped cards, booted without caches and it's working good. The only thing that isn't working openCL. What do I have to do to enable it? Link to comment Share on other sites More sharing options...
Administrators Hervé Posted January 22, 2017 Administrators Share Posted January 22, 2017 Nothing, the card either supports it or doesn't and the Radeon HD 6670 does. It's more a matter of drivers and apps. You can run tools like OpenGL Extensions Viewer (free off AppStore) or others to check out your card's capabilities. OpenCL usage largely depends on apps that call onto it. https://support.apple.com/en-us/HT202823 Link to comment Share on other sites More sharing options...
