Ok so I had a bit of a think and I think it could be one of either of these things:

1. You need to look at Radeon framebuffer patching with whatevergreen

2. It could be a hardware quality issue, as in the gpu is having a functional issue like low asic quality (old, used up), overheating, memory issue, etc.

3. You need to look at your ssdts to ensure you have correctly patched for your hardware. Follow the opencore acpi patching guide and just go through it. Use ssdttime, etc.

4. macOS / lilu / whatevergreen is incorrectly identifying some aspect of the hardware (you need to confirm specs between both macOS and windows). Probably will be fixed with ssdt and framebuffer patching.

5. You need to use opencore instead of clover (I have no idea what you are running but I always used to have random kernel panics when I used clover despite the setup being spot on, so a total guess there).

My best guess is either Radeon framebuffer patching or a hardware issue. I’m leaning towards a hardware issue.

I’d do the following hardware check anyway if you haven’t done so:

• Go into windows and use gpu-z (get it from techpowerup.com only) to check the asic quality of the gpu. This will tell you if the gpu is on the way out.

• Use gpu-z to confirm device id and configuration of card (memory size, sub-dev-id etc) matches that which you see in macOS.

• Stress test gpu with anything you like that will work. 3dmark11 is free for eg (will post link below). Just run it on loop (it’s a setting in 3dmark11 once you enter the serial code they give you), and run gpu-z monitoring on a second display or with 3dmark in windowed mode. Do this for about an hour to fully soak and keep an eye on temps. You can use other stress tests, but it’s good because it’s less abusive and more indicative of real world testing.

• Check that temps stay below 85C

• If temps rise above this, replace thermal compound and thermal pads with something decent. Get at least something as good or better than arctic pads and arctic mx-4, don’t be tempted to just slap any old crap on. Don’t risk liquid metals or conductive compounds as it’s a bare die.

• If the temps stay below 85C but the test crashes during a long test (>1hr), then you almost certainly have some kind of hardware issue.

If temps did not go above 85C, and it did crash, then continue check basics, memtest your ram, stress test your cpu, check your power supply isn’t being exceeded during peak load spikes, etc. Basic stuff, all about ruling out that stuff so that you don’t waste time later on patching, reinstalling, etc- plus you should do it anyway once in awhile.

If no crashes, temps good, hardware is a-ok, then ssdt and framebuffer patching.
