Radeon R9 270x Framebuffer/ID problem?

8 posts in this topic

Recommended Posts

Hi all! My first post here  :)

 

First of all, I want to say a warm hello & thank you to everyone on here! InsanelyMac has pulled me out of the s**t many a time before now!  :rofl:

 

On the topic of this graphics card - I have followed Vlada's InsanelyMac post (Here) regarding this GPU & I haven't had much luck!

 

Basically, I have the Sapphire Radeon R9 270x running on (Niresh) Mavericks 10.9.2 - it's displaying as 'Radeon HD 7xxx 2048 MB'.. I am getting full resolution, and I assume QE/CI is working as I can make a move in Chess. However, running a LuxMark benchmark I am getting a "clBuildProgram -11" error, and in Unigine Heaven I am barely scraping 10fps with the settings on Extreme  :(

 

I have tried installing Vlada's driver package and it just gives me nothing (Black screen on DVI, screen goes off completely on HDMI). I have tried the Terminal method too, still no luck. The only section I could not follow properly was the DSDT section - I couldn't find the "PEGP" device in MaciASL, my Graphics Card is on PC02 according to IORegistryExplorer.

 

So I guess my question is, has my n00b level reached a new extreme & I'm missing something completely obvious? Or should everything be working?

 

BTW, I have another Mac installation on my second HDD, so copying/restoring {censored}-ups is easy enough for me!

 

 

Thanks in advance!  ^_^

Conor

Hello everybody. I`ve just successfully patched my Asus R9 280X. Everything is OK. BUT!

I can`t understand why pushing on "monitors" in settings, system settings freeze. 

Before patching i had same situation.

Yosemite DP6.

 

Anybody know why it happens?

Does system preferences freeze or does your entire computer freeze? You should check if you can see any Console messages when it happens.

 

I don't know how many displays you are using, but try booting with a single display at a time from each port, and see if there's a particular port that's causing it. If you can find that only 1 port is causing it, maybe try different control flags for that port.

Ah fair enough, thanks! I'll report back when I manage to get Clover working  :) keeps restarting on me after UUID at the moment!

      Problem:
      When I Attempt to wake my Machine from sleep, the screen stays black, although the computer is obviously awake !
      This Machine has a 1300W Power Supply So Sleep is Very Useful.
       
      I Tried:
      1) FIX_WAK and FixShutdown as per Clover Wiki.
      2) Although I am using "SAPPHIRE Radeon PULSE RX 580 8GB GDDR5", which Should be completely Supported by Mojave, I Also changed the Part Number to "113-4E353BU-O4E" as per this Guide: http://www.xlr8yourmac.com/archives/feb18/RadeonRX-580_MacPro.html. The GPU is working GREAT without even Clover Inject
      3) Tried to Run this command: disablehibernate.command.zip
      4) Tried darkwake=0 to 10
      5) Disabled wake on USB & Wake on LAN (BIOS)

      Hi,
      I have the following system:
      - Gigabyte Z370M-D3H M-ATX
      - Core i7-8700K Coffee Lake
      - Gigabyte Radeon RX 560 4GB
      - Crucial Ballistix 16GB DDR4
      - 960 EVO 1TB NVMe SSD
      - 850 EVO 500GB SSD
      - Crucial 500GB SSD
      - The 2 500GB SSD's run in Raid for data storage.
      - Western Digital 3TB HDD - Time machine
      - EFI here (too large to attach): EFI.zip

      Questions:
      1. I have a dual screen running from Radeon card, 1 on DP and 1 on HDMI. The one screen on DP goes randomly blank from time to time. Any ideas?
      2. I've read that the kexts should preferably be installed in /library/extensions. I would like to know what kexts should remain in the EFI. I read that you should install FakeSMC in both locations (EFI and L/E). If I follow this route must I change something in the config.plist?
      3. USB info in System Information (attached does not seem correct. I've followed the changes suggested but I'm not sure if this is the best it can be.
      4. Are there something in the EFI and config.plist I don't need or doing wrong?

      Feedback will be appreciated.
