So I got a Hackintosh with an ASRock B85M Pro4 Motherboard, an Intel i5-4440 @ 3,2 GHz and a Sapphire R9 390X Nitro 8GB GDDR5 running OS X 10.11.4 with Clover Bootloader. I got a very annoying issue: After irregular period of time the screen turns black (not video signal lost) or the System freezes (this phenomenon rarely happens).
So obviously this is an GPU related problem since under "Diagnostics Reports" there are Log files generated titled "Kernel GPU Restart": Here is a file attached, that includes the Log files, maybe somebody can read sth out of it and might tell me, whats the reason for this issue. Note: My GPU is supported by OS X out of the box and hence Injecting ATI or adding a fake ID is unnecessary.
What I already tried to fix this issue: * Patched the SSDT & DSDT: Thought this would be a power management issue, so I did this in hope that it would solve my problem. Unfortunately it didn't. * Checked LoadVBios: Attached the exported GPU BIOS from GPU-Z and placed it on my EFI partition. * Added another Framebuffer name for this card in Clover Configurator ("Baladi" and "Radeon") and added a framebuffer patch for the 290X / 390X (as I said unnecessary and did not work anyway).
So, I'm currently at the point I get a lil bit frustrated because I do not have any clue how to solve this problem / what causes this problem, so I'd really appreciate your help!
