enzocodini Posted February 26, 2016 Share Posted February 26, 2016 Well, the title says it all! It worked flawlessly in 10.11.3 El Capitan. Verde.kext was needed, though! I just followed instructions for HD 7770. Using Clover UEFI, only works in EFI mode (at least mine). Model: ASUS Radeon R7 250X 1GB RAM DDR5. Also don't use InjectATI!

fantomas Posted February 26, 2016 Share Posted February 26, 2016 Hi I'm glad it's working for you You have to know that a R7 250X = HD 7770, nothing more, nothing less. These cards should work OOB (Device-ID 0x683D1002 is already in AMD7000Controller.kext + AMDRadeonX4000.kext) without any special boot flag or inject ATI feature checked.

I know, if i didn't i wouldn't have tried. Also, since 10.10.3, i don't know what Apple did, but i had to use an enabler to correct some graphical bugs and/or a black screen when system booted. Feels like correcting the FX 5200 bugs in 10.5. Gosh, that was really long ago! Link to comment Share on other sites More sharing options...
Kneize Posted March 9, 2016 Share Posted March 9, 2016 Hi, any thoughts about why Sapphire HD 7750 can bring artefacts? Verde.kext allows me to boot and log in in system but it unusable. Link to comment Share on other sites More sharing options...

That's weird. I'm not sure if the 7750 works with Verde.kext, but you can try different framebuffers. EDIT: I read somewhere that you can edit the AMDRadeonX4000.kext in the AMDVerdeGraphicsAccelerator key and in call_properties option to this: <key>cail_properties</key> <dict> <key>CAIL_DisableDrmdmaPowerGating</key> <integer>1</integer> <key>CAIL_DisableDynamicGfxMGPowerGating</key> <integer>1</integer> <key>CAIL_DisableGfxCGPowerGating</key> <integer>1</integer> <key>CAIL_DisableGmcPowerGating</key> <integer>1</integer> <key>CAIL_DisableStaticGfxMGPowerGating</key> <integer>1</integer> <key>CAIL_DisableUVDPowerGating</key> <integer>0</integer> <key>CAIL_DisableVCEPowerGating</key> <integer>1</integer> </dict> Good work! I have the same graphic card, but mine doesn't works! Can you show me your clover configuration? Thanks! And sorry my bad english! :') Where are you stuck? I had GraphicsEnabler=No (i used clover, the card only works if you're using UEFI, so think it was InjectAti=Yes, but try with No too) and Verde.kext installed, that's all.
