    Won't Wake from Sleep and Reboots with Radeon RX 480/580

    It depends on what you are trying to achieve. That SSDT file was required during High Sierra days but Mojave, things have progressed and should not be necessary.

    Radeon RX 4XX/5XX standalone system, AMDRadeonX4250.kext (GVA support H264) does not support HEVC HW

    Both GPU's "working" does not mean dGPU is encoding...it will decode but not encode WITHOUT the dummy kext (unless you are using 10.14.5 BETA). You can prove it to yourself by examining the IOREG WITH and WITHOUT the dummy kext. See this.

    Radeon RX 4XX/5XX standalone system, AMDRadeonX4250.kext (GVA support H264) does not support HEVC HW

    That comment seems a little disrespectful. Joining date should have no relevance on expertise or knowledge.

    Radeon RX 4XX/5XX standalone system, AMDRadeonX4250.kext (GVA support H264) does not support HEVC HW

    For your CPU, it's better to use iMac13,2 - it's the closest match. For proper CPU power management, you need to set the right config parameters (XCPM or SSDT.aml) but that's outside the scope of this thread and you should start a separate thread in the desktop section where others will help...

    Radeon RX 4XX/5XX standalone system, AMDRadeonX4250.kext (GVA support H264) does not support HEVC HW

    That's normal. Your options are: 1. Enable IGPU in BIOS, Inject->Intel=Yes, and use connector-less ig-platform-id=0x01620007. Or, 2. Change SMBIOS model type to iMacPro1,1. But you will get green glitches in the H.264 output. Or, 3. Keep your SMBIOS as-is and add boot flags: shikigva=32 and...

    Radeon RX 4XX/5XX standalone system, AMDRadeonX4250.kext (GVA support H264) does not support HEVC HW

    NOT correct advice. WITHOUT the dummy kext, the RX4XX/RX5XX will not be utilised and you will only get Intel Quicksync/Software encode/decode which is fine and will work. BUT, that's the not the purpose of this thread here (which is to try and use the AMD GPU for encode/decode).

    Radeon RX 4XX/5XX standalone system, AMDRadeonX4250.kext (GVA support H264) does not support HEVC HW

    I am on MacOS 10.14.4. I enabled the IGPU connector-less (needed enable H.264 encode/decode WITHOUT green artefacts) I installed Dummy141.kext in EFI/Others (needed to enable HEVC encode/decode in RX580) I use SMBIOS iMac13,2 I have DSDT.aml and SSDT.aml (for CPU power management) For H.264...

    The green line shows that the IGPU is still active. Check your BIOS setting again.

    Radeon RX 4XX/5XX standalone system, AMDRadeonX4250.kext (GVA support H264) does not support HEVC HW

    OK the first screenshot with the Intel Power Gadget, shows that you have IGPU enabled (the green graph line). It also shows that the CPU is maxing out at 4.0GHZ. This implies that even though everything "works" and "perfect" for you, your system is using the CPU and IGPU to do the encoding (i.e...

    Radeon RX 4XX/5XX standalone system, AMDRadeonX4250.kext (GVA support H264) does not support HEVC HW

    Again, without screenshots of your IGPU and dPGU loading, your screen shot does not show which GPU is doing the encode in FCPX. Why don't you provide those screenshots as well ?

    Radeon RX 4XX/5XX standalone system, AMDRadeonX4250.kext (GVA support H264) does not support HEVC HW

    Those screenshots show that Premiere will do the h.264 encode but it does not show with which GPU. You need to run tools to show the loading the IGPU and the dGPU. (e.g. Intel Power gadget and Activity Monitor). If H.264 encode is truly being executed by the dGPU then, it's load & utilisation...

    Radeon RX 4XX/5XX standalone system, AMDRadeonX4250.kext (GVA support H264) does not support HEVC HW

    It's not sufficient to say "perfect" without first checking what is actually doing the encoding. If you have IGPU enabled, then you need to confirm if it is doing the encoding or the dGPU. That is, you need to prove to yourself that the encoding is done either by IGPU, dGPU or both.

    Radeon RX 580 - Screen flashing during boot

    NO. Not found any work around. I have not seen any issues regarding static noise. Bad cable ?

    AMD RX580

    With Mojave beta, it is trying to use the GPU for h.264 but not very well.

    How to solve the black screen with RX 470 in High Sierra 10.13.6?

    If you are trying Mojave, then I'm afraid your motherboard/CPU is too old and not supported as iMac10,1

    Radeon RX 4XX/5XX standalone system, AMDRadeonX4250.kext (GVA support H264) does not support HEVC HW

    You are having lot of success BUT you are still have IGPU enabled with iMacPro1,1. Check the IGPU & RX580 loading while encoding H.264 to HEVC, H.264 to H.264 and HEVC to H.264. That is, is it really using the RX580 or IGPU or BOTH ???

    Radeon RX 4XX/5XX standalone system, AMDRadeonX4250.kext (GVA support H264) does not support HEVC HW

    So, what's the current solution (with 10.14.3) to enable HEVC AND H.264 encode in FCPX ? Specific model ID, framework hack ?, dummy kext ? WEG ? After 647 post, I seem to have lost track :)

    [Solved] Sapphire RX 580 Nitro+ SE | black screen on HDMI and DVI

    PlistEdit Pro App. I do not use Clover Configurator..seems to mess up the .plist files some times.

    Radeon RX 4XX/5XX standalone system, AMDRadeonX4250.kext (GVA support H264) does not support HEVC HW

    It's just that in post #10, you said if one sees VCPHEVC then software decode is taking place for the VTDecoderXPCService but that does not apply in VTEncoderXPCService ?
