My specs are CPU: Xeon E3-1230V3 MB: MSI Z87-GD65-Gaming Graphic: Sapphire R9 290X Tri-X OC.

I have 10.11.6 installed. I am using the latest Clover Bootloader. I made this CustoMac to do some graphic works but it only gets recognizes 7mb. 

 

I will list up what i did and make what to boot up.

1. If i use 290X Fake ID(0x067B01002) it doesn't boot up.(** GPU Hardware VM is enabled (multispace: enabled, page table updates with DMA: enabled)

I have to type 0x67B11002 to boot up. (I added 0x67B11002 to AMD8000Controller.Kext & AMDRadeonX4000.Kext)

 

2. If i uncheck inject ATI it doesn't boot. 

 

3. I need this part in config.plist to boot up. if this doesn't exit bluetooth transport error comes up.

    </dict>

 

4. Checked bootlog. It sets my VRAM to 4096mb. But inside mac it says 7mb and has a hole lot of lags.

3:899  0:000  Set VRAM from config=4096Mb

3:899  0:000  ATI: get_vram_size returned 0x0

:900  0:000  ATI Radeon EVERGREEN family
3:900  0:000  Users config name Baladi
3:900  0:000   use N ports setting from config.plist: 4
3:900  0:000  (AtiPorts) Nr of ports set to: 4
3:900  0:000  ATI Hawaii AMD Radeon R9 290X 4096MB (Baladi) [1002:67B0] (subsys [174B:E285]):: PciRoot(0x0)\Pci(0x1,0x0)\Pci(0x0,0x0)

5. I tried Every ATI Controller settings in the forum and tonymacx86 forum but it doesn't work to me

6. I have dual monitor (27" alphascan & 24" Yamakasi) but it only recognizes as 30.5" inch 1 monitor

7. AMD Radeon GPU injector doesn't work.

8. In DPCI Manager My graphic says ' Framebuffer = .Display_boot ' I tried Hawaii, Exmoor, Radeon, Baladi, AMD, Tahiti ...

9. In PCI List My graphic says ' 1002, 67B1, 174B, E285, Advanced Micro Devices, Inc. [AMD/ATI], Hawaii PRO '

290x is nativly support. Don't do nothing. Delete fake id and delete injection i GPU clover section.  Just insert GPU to slot and boot system. 

I also did that but it gave me a just a gray screen. just in case I entered my password + enter I logged in but I only can see my wallpaper. That was all i could do.

Try this solution:

http://www.insanelymac.com/forum/files/file/424-agdpfix/

 

Or You can try to change CSM in bios boot settings. 

In my case when is diseble Mac boot to black screen. 

I Tested agdpfix but it didn't work .. i tried CSM also but it didn't work.

I would rather switch the port on the GPU to connect the monitor, since the gray screen and the wallpaper shows that the card seems to work, but the port might be identified as secondary.

Reinstall system and try again. I reele dont know what is wrong. I have this GPU and evryfing is working without any changes in config and kext.

I got things more worse with reinstalling.. now only one monitor comes up and boot.

I would rather switch the port on the GPU to connect the monitor, since the gray screen and the wallpaper shows that the card seems to work, but the port might be identified as secondary.

I tested everyport that I could try. and tested every combination. And I found out that when I enter nothing in graphics. the gray screen and wallpaper come out because it detects the VRAM as 2.5mb

Hi guys ! I don't know if i have to create new topic or post on this one... I have the same problem with a R9 290 (non X). I was on Yosemite and since i updated to capitan, my r9 290 has only 7mb vram. I tried a lot of solutions found on forums, but nothing worked... I also have 2 FHD monitors : one on DVI, second on HDMI.

 

I installed AMD 9000 + 8000 + 4000 + framebuffer kexts.

 

Here is my config.plist : http://filetransfer.fr/download.php?file=9A51MZ20B8

 

My config :

 

- i7 4790k

- MSI Z97 Gaming 5

- 32GB DDR3

- R9 290

- 1 SSD 500GB (Windows) + 1 SSD 250GB (OSX) + 2 x 2TB HDD

 

I need to make it works quickly because of my job... so please help me :(

 

Thanks a lot !
