AMD Radeon RX 550 - 560 injected with Opencore macOS Big Sur

[ori69]

I made work a RX 550 4GB from China.
Also a Radeon PRO WX 3200 4GB that has 640 shaders. I get the expected video resolution and 4GB DDR5.
System info SMBIOS iMacPro1,1 the WX 3200 doesn't get H264 acceleration both in Final Cut Pro and Handbrake and possibly any other app, while with the RX 550 from China I get H264 hardware acceleration.

Does anybody know why is that? The WX 3200 (640 shaders) must be polaris to load the driver, show 4GB DDR5 but then why the H264 acceleration doesn't run?

Platform: X299

Yeston RX550 4HDMI

and HP RX550

The system has already recognizes both RX550 0 and 1

but there are no decoding:

When loading there is such a message:

Check out zzmadd's post here, and check the first line of the device properties. You'll need to add it to both your cards PCIRoot paths, and make one line @0,compatible - pc1002,67ff and the other card's key as @1,compatible - pc1002,67ff >

With Alder Lake being so new, I'm really glad there are those pushing the development of getting macOS running on the new platform. Personally, I'm pretty happy with my workflow and running with my almost 3 year old Z390 Designare with 9900K for music that has been flawless and still plenty of...

I have added. Both cards are already correctly recognized, but no encoding does.

How do you look like a Videoproc test?

You clearly haven't set the parameters correctly. Look again at the settings required (this is from zzmadd's config.plist):

I did exactly the same. 2 RX550 cards are detected, there is metal support. But there is no decoding. Can you check how it looks like?

Did you mark the first card in the device-properties as @0,compatible and the second one as @1,compatible?
Because it should technically work. The only issue I can think of is if you haven't designated one as 0 and the other as 1, it doesn't know which to pass it to.

@zzmadd work the H264 acceleration?

@ori9
I think I know the reason why your card is not working on H264.
It is still not spoofed to 699f. So long as that is the case, the system doesn't recognise it.
Your SSDT-GPU-Spoof and device-id must be set to 699F not 67FF for it to work.

this only change the name, still have the same issue 7MB Vram

You need to make an SSDT. On this principle. Spend special attention on Device D012. You may have your own.In your DSDT. Or a few .

This is the principle in general. Here you need _STA in your DSDT to assign the value Zero.True as in this SSDT. Sorry for my English
