AMD Radeon Navi GPU

[mattystonnie]

Help please. No fan / temp readings. Sapphire Pulse 5600 XT. Injected playtable. But does not work due to no data to react on.
It is connected to PCI 0,6,0 - so considered internal.
connected to a NVMe X4 port as I have not PCIe slots.
Tried many things. Do I need a specific Mac
Model ?

We are doing tests there, also I will need a ioregistry copy.

I just tried a small ProRes file and was able to convert it to H.264 using Quicktime. I didn't look at CPU usage but it completed without errors. I am using the SSDT and WEG.

@svandive shikigva=80 was somehow blocking the iGPU from transcoding to h.264 in Quicktime, but gave the most DRM possibilities all around.
No Shikigva: Netflix on Safari works, but Amazon Video on Safari and movies on TV+ do not. However, transcoding in QuickTime works 100%, which is more important to me.
This will be ok for now, but would be nice to solve it completely. Will keep testing.

I am using a Sapphire Radeon 5700 XT Pulse graphics card.

I encounter computer freezes if I run some kind of video in the first 15 minutes after turning it on. Sometimes my cursor moves, as in this video. After sleep, I do not observe such a problem.

Using the latest version of OpenCore from ModMike, it works great for me.

What can this problem be connected with and how can it be solved?

I am using an LG 27UL850 monitor with built-in speakers. My monitor is connected to a graphics card via DisplayPort

I also had freezes with my AMD card until I deactivated everything that seemed to be related to PCIe power saving in the bios.

I have an Sapphire AMD 5700 XT Pulse with this problem on macOS 10.15.4.

Please tell me what parameters you disabled in the BIOS?

Holy smokes!! I used Araguaia for my Radeon VII on OpenCore...

@pastrychef
I have Radeon VII too on my Asus (on Clover at the moment), can you share the SSDT?

Should this solve the problem?

You are free to try, I do not experience freezing problems.

At the time of posting, I was using the SSDT on post #818. I've since switched to the kext on post #830/850.

Test, see if it works.

I have asus tuf mark 1 with 7900x , I am testing this ssdt with these properties in config adder in my clover that I do not know if they are completely correct for my platform, I use a sapphire 5700xt nitro plus.

It has started me, I cannot see the temperature of the 5700xt but if it gives me more punctuation in the tests

Should I change something in this dsdt or is it valid for all asus x299? Are the properties in clover the same for all 5700xt models?
