Acceleration on Asus Radeon HD 7850 2GB?

1 post in this topic

Recommended Posts

I have an ASUS Radeon HD7850 with 2GB of VRAM. I'm on Yosemite 10.10.2, using Clover. Yosemite only reports the GPU as a Radeon HD 7xxx 2048 MB, and I don't think it's being fully accelerated. I've been looking all over but I have no clue what to do. I've used tai-personality.pl, used radeon_bios_decoder, redsock_bios_decoder, and I've set Clover to inject ATI and use the Aji frame buffer. This made my computer screen go black after the boot bar, and sleeping and waking the computer did nothing - same with the Futomaki frame buffer. I downloaded a modded AMD7000Controller kext for an HD7850 and used inject ATI + Aji frame buffer, but when i restarted, my screen was not the right resolution, colors were off, everything was laggy. OS X reported the GPU as an HD 7850, but with only 7mb of VRAM, so obviously that kext was incompatible. What do I do for full acceleration? I've attached my DSDT, my radeon_bios_decoder output, and my redsock_bios_decoder output.

 

EDIT: Turns out I wasn't in sleep mode. When the computer actually went to sleep and I used the Aji profile, and waked up the computer, the screen turned on and Yosemite reported it as an HD7850 2048 MB. So now I just need a solution on how to keep it this way, without having to always restart.

      Clover r4542 ISO compiled with GCC and minimal config.plist compatible for use in VMWare Workstation.
       
      Tested with unlocked Workstation 14 running OSX 10.9 -->10.14 guest in Windows X64 host.
       
      Installation
      1. Download and unzip "EFI_Clover_r4542 for VMware.zip". Mount Clover-v2.4k-4542-X64.iso by double clicking on it.
      2. Mount your VM's EFI System Partition eg in terminal
      sudo diskutil mount disk0s1   3. Copy EFI folder from step 1 into the EFI partition
      4. Shutdown the VM, add bios.bootDelay = "3000" to your VM's vmx file
      5. Reboot your VM, press <F2> to access the VMware Boot Manager and add CLOVERX64.efi to the boot menu.
       
      Substitute your own unique and valid MLB and ROM variables in the /EFI/CLOVER/config.plist (Rt Variables section) to activate iMessage/Facetime on your VM.

      Hi guys, this thread is to show you a new and open source app, created by me, that I called TINU:
       
      The name means: TINU Is Not #####, the U refers to a popular software that is used to create Mac OS hackintosh installers (that for good reasons is banned on this forum), but the aim of the name is to explain that this app is a totally different thing from that software and works in a totally different way.
       
      This app basically is a graphical interface for the createinstallmedia executable that is inside the Mac OS installer apps, it is capable to create a Mac OS installer on a drive completely vanilla like what you do using the command line method, and also this method is recommended by apple itself. In addition to this, this app provvides also to you some customization features and a better management of the hall macOS isntall media creation process
       
      Allows you to create easily a macOS install media without messing around with command line stuff and without using disk utility, all you need to do is use the app and then install clover on the usb drive once TINU has finished or leave it as is you want to use it on a Mac.
       
      Features:
        - Simple to use UI that allows you to easily start the macOS install media creation process
        - It can work with every Mac OS installer app that has the createinstallmedia executable inside of it's resources folder (including also beta and newly released installers)
        - You can use any drive or partition you want that can be erased and is at least 7 GB of size
        - Works on Mac OS recovery, so you can create a macOS install media from a bootable macOS installer or from the macOs recovery, and you can use TINU to install macOS too.
        - All vanilla, the macOS install medias created with this tool are 100% vanilla, just like you created them using the command line "createinstallmedia" method in the terminal, with also some extra optiona features
        - Open source, you will know what this program does on your computer and also you can create your own version by downloading and playing with the source code
        - Does not requires to do anything of special first, just open the program
        - No need to go in disk utility first, TINU can format your drive for you
        - Uses recent and more modern APIs and SDKs and Swift 3 language
        - Transparent graphics style available (use alt + s on the keyboard or View->Use transparent style)
        - Works using the latest versions of macOS and will also support newer Mac installers out of the box without needing for an update
        - Advanced section, to customize your macOS install media
        - Installer customization: Kernelcache/prelinkedknerel and boot files replacement (a feature that can be handy while dealing with old Macs or with beta installers when you need to mod or change the boot files some times)
        - Clover EFI folder installer
       
        Features that are planned for some future versions:
        - Integrated EFI partition mounter tool (TINU can already mount EFI partitions from version 2.0, but a dedicated section which allows to mount every EFI partition in the system will be added)
        - Install clover and configure clover
        - Install kexts inside the kexts folder of clover
        - Clover drivers customization
        - Use custom dsdt in clover
        - integrated pre-made clover config templates database from a remote and open repository
        - Support for other languages, at least Italian   Rquirements:  - A computer that runs Mac OS X Yosemite or a more recent version (Mac OS X El Capitan is required to use TINU in a macOS recovery or installer)  - A drive or a free partition of at least 7 GB that you want to turn into a macOS/Mac OS X installer  - A copy of a macOS/Mac OS X installer app (Maveriks or newer versions are supported) in the /Applications folder or in the root of any storage device in your machine (excepted the drive or volume you want to turn into your macOS install media)   Note that this app is under the GNU GPL v3 license so any reuse of the source code must follow the license's terms   Latest stable TINU release:   Download the app:                                https://github.com/ITzTravelInTime/TINU/releases   View the source code:                            https://github.com/ITzTravelInTime/TINU       Frequently asked questions about TINU:  https://github.com/ITzTravelInTime/TINU/wiki/FAQs     NOTE: if you have problems with your USB installer of 10.13.4 or newer version not being detected by clover you have to use the latest clover and if it still does not detectets your usb installer you have to remove the invivible file called .IAPhysicalMedia located into the root of the usb installer. This issue is caused by a changement in the apple's createinstallmedia, don't blame TINU for that, TINU does only uses the installer creation method from apple, which has been changed by appleitself, causing this problem for hackintosh users some times, this issue should be resolved in the latest versions of clover which will no longer require that you do changements to let your usb dive to be detected, a setting to do this fix automatically in tinu is also present TINU in the adavnced settings, starting from the version 2.0 of the app. I leave also some screenshots as well

      1 - Preparando PENBOOT:
        1.1 - Baixe a imagem do Sierra e deixe na pasta "Applications";
        1.2 - Formate o PenDrive e altere o nome para: "MyVolume";
        1.3 - Abra o Terminal e digite a seguinte linha de código, dê enter e quando solicitado digite sua senha. Aguarde o término da instalação, geralmente demora em torno de 20min:
      sudo /Applications/Install\ macOS\ Sierra.app/Contents/Resources/createinstallmedia --volume /Volumes/MyVolume --applicationpath /Applications/Install\ macOS\ Sierra.app  
       
      1.4 - Baixe a última versão do Clover EFI bootloader: Download
        1.5 - Abra o Clover, na última etapa, clique em Customize, depois marque a opção "Install for UEFI booting only", como na imagem abaixo:

       
        1.6 - Provavelmente a partição "EFI" estará montada, abra a partição e substitua a pasta "CLOVER" por esta CLOVER Asus X99 Deluxe II - Sierra.zip.
       
      2 - Configurando BIOS
        2.1 - Atualize sua BIOS para a versão mais recente, a minha é: 1902
        2.2 - Reset as configurações de sua BIOS em: Exit/Load Optimized Defaults;
        2.3 - Vá para: Boot/CMS (Compatibility Support Module)/Launch CMS: ENABLED;
        2.4 - Vá para: Boot/Secure Boot/OS Type: Other OS;
       
      3 - Instalando OS
        3.1 - Ligue o computador com o Pendrive espetado, ele automaticamente irá iniciar o Clover, caso isso não aconteça, na tela inicial da ASUS, pressione F8 para escolher o pendrive como boot primário;
        3.2 - Em algum momento futuro, seu clover pode não arrancar corretamente, caso isso aconteça, na tela inicial do CLOVER pressione F11 para limpar o NVRAM, ele irá reiniciar a máquina automaticamente, em seguida voltará a arrancar normalmente;
       
      4 - PÓS-INSTALAÇÃO
        4.1 - Inicie seu MAC temporariamente pelo Pendrive como boot primário;
        4.2 - Instale o clover seguindo as etapas 1.4, 1.5 e 1.6 . Apenas não esqueça de alterar o destino para o HD Interno com a instalação do Sierra.
        4.3 - Feito isso, reinicie seu mac, agora sem o pendrive;
       
      5 - VÍDEO
        5.1 - Na pasta CLOVER que anexei acima, já possui as kexts NvidiaGraphicsFixup.kext e Lilu.kext ;

      Hi,
       
      I thought it would be nice that I would be the first here to give my experience with getting Mojave running and mostly working on my system.
       
      My specifications are as follows:
       
      iMac 14,2
       
      GIGABYTE GA-Z97X-UD5H / Intel Core i7-4770k @ 4.4GHz / 16GB Corsair Vengeance DDR3 @ 1600MHz
      MSI AMD Radeon HD 7870 2GB OC
      250GB SanDisk Ultra 3D NAND SSD / 120GB OCZ Agility 3 SSD
      1TB 5.4K HDD
       
      I used the config that @MaLd0n helped me with. Seriously, he is a legend. HERE is my Clover Config including everything I use for 10.13 High Sierra and 10.14 Mojave.
       
      Installation Procedure:
       
       
      Create bootable USB media with createinstallmedia - sudo /Applications/Install\ macOS\ 10.14\ Beta.app/Contents/Resources/createinstallmedia --volume /Volumes/"Insert Volume Name here"  ***** Remove quotation marks!!! 
       
      **"--Applicationpath" is now depreciated and should not be used when making a 10.14 Mojave USB. I do not know if this will change in upcoming releases.
       
      ** ConvertToAPFS is now depreciated and no longer works when installing 10.14 Mojave beta 1. Using the command "--converttoapfs NO" will not work if you use it with "createinstallmedia".
       
      Editing "minstallconfig.xml" within the "macOS Install Data" folder on the target partition chosen during installation to change "ConvertToAPFS" from "TRUE" to "FALSE" would also not disable APFS conversion.
       
      Installation ran through well, but it did restart just after installation began which seemed to have been caused by a crash, but it seemed like it was normal as this happened twice as I tried installing Mojave earlier and the same thing happened. Rebooting again into the installation on the target drive that was selected before described as "macOS Install"  and named "macOS 10.14" resumed installation.
       
      Everything from then on was easy and smooth. I set-up my iCloud and things as such and was brought to the desktop of macOS 10.14 Mojave!
       
       
      What does work:
       
      Graphics (Acceleration/Metal) // 4K video dropped 0 frames // Picture-in-Picture
      Mouse and Keyboard
      USB 3.0 -  Full 5 GBP/s - Only ports above HDMI Port and front I/O
      USB 3.0 under both Intel and Killer Ethernet ports function with USB 2.0 devices.
      Ethernet (only Intel NIC so far) Both NIC's work, Intel I217-V and Killer E2200
      iMessage
      Sleep and Wake
      Shutdown
      Restart
       
      Update #1:
       
      Temporary Fix: ***I have gotten audio to work after browsing Reddit, I stumbled across this post: https://www.reddit.com/r/hackintosh/comments/8orn7w/mojave_files_needed/e05kkj9/
       
      Update #2:
       
      I have just found a kext for the on-board Killer E2200 NIC after searching with device and vendor ID's on this forum.
      https://www.insanelymac.com/forum/files/file/313-atherose2200ethernet/
       
      Update #3:
       
      Audio is now fully operational with new version 1.2.8 of AppleALC, from here: 
       
      What does NOT work:
       
      USB 3 under Intel I217-V NIC and Killer E2200 NIC Ethernet Ports // Only function with USB 2.0 devices.
      Audio Temporary fix in Update #1 above   Fixed in Update #3
      Killer E2200 NIC Fixed in Update #2 above
       
       
       
      This is the information I have been able to gather thus far whilst using Mojave.
       
      I hope this helps someone in getting Mojave running on their system.
       
      Regards,
      Mohamed
