Como corrigir a memória de video

7 posts in this topic

Recommended Posts

Em alguns casos o GraphicsEnabler do Chameleon funciona para ativar o vídeo, porém a quantidade de VRAM aparece errada. Isso é apenas visual, mas para quem quiser acertar, aqui vai uma forma:

 

Rode este comando no terminal para obter o string device-properties gerado pelo Chameleon:

ioreg -lw0 -p IODeviceTree -n efi -r -x | grep device-properties | sed 's/.*<//;s/>.*//;' > ~/Desktop/device-properties.hex

Converta para plist (coloque o gfxutil.zip no desktop)

cd ~/Desktop
./gfxutil -s -n -i hex -o xml device-properties.hex device-properties.plist

Edite a VRAM no device-properties.plist   

<key>VRAM,totalsize</key>
<string>0x40000000</string>

O valor está em hexa, pode converter para decimal usando a calculadora no modo programador, mas normalmente basta dividir ou dobrar o valor que você já conhece.

 

Exemplos:

0x20000000 = 536870912 (bytes / 1024^2 = 512 MB)

0x40000000 = 1073741824 (bytes / 1024^2 = 1024 MB ou 1 GB)

0x80000000 = 2147483648 (bytes / 1024^2 = 2048 MB ou 2 GB)

 

Converta o device-properties.plist editado para hex

./gfxutil -i xml -o hex device-properties.plist device-properties-new.hex

Copie o string do arquivo device-properties-new.hex para a chave device-properties no arquivo /Extra/org.chameleon.Boot.plist

 <key>device-properties</key>
 <string>cole o string aqui</string>

Desative o GraphicsEnabler (ou remova a opção)

   <key>GraphicsEnabler</key>
   <string>No</string>

Para quem usa Clover o ajuste pode ser feito através da opção VRAM no config.plist

  <key>Graphics</key>
   <dict>
      <key>Inject</key>
      <true/>
      <key>VRAM</key>
      <integer>1024</integer>
   </dict>

Allan, te comento que el link a gfxutil requiere login para descargar en Olarila. Subelo aquí que será mas directo. Gracias por la guía!

 

EDIT: puedes borrar este post si quieres para que este mas limpio el hilo.

Olá

 

Grande guia esse ai do Olarila, me ajudou quando comprei minha GTX 760 e dava 0mb kkkkk ajustei e pronto e no momento eu estava usando Chameleon

Só uma coisa allan: Seria muito bom se fosse colocasse nos créditos o link do guia e o nome do usuário que o criou originalmente :)

 

Pro chameleon eu tenho que baixar um comando, rodar um comando no terminal e ainda fazer umas matemáticas.....

Pro Clover é só colocar o tamanho da memoria e pronto

 

Isso só me dá um pensamento: Clover=usuario normal ou leigo se usar HV/Chameleon=usuario que faz tudo na manual e não tem medo de enfrentar códigos, linhas e até uma matemática  :P

No Chameleon fica assim :

 

<key>device-properties</key>

 <string>cole o string aqui</string>

 

No Clover é a mesma coisa?

Não, no Clover o ajuste fica na chave VRAM e é bem + fácil veja um exemplo:

 <key>Graphics</key>
   <dict>
      <key>Inject</key>
      <true/>
      <key>VRAM</key>
      <integer>1024</integer>
   </dict>

1024 é só um exemplo, pois 1024MB=1GB, 2048MB=2GB e por ai vai, isso depende do tanto da tua memoria sendo que ela deve ser sempre expressa em megabyte.

      Hello guys!
       
      Here's how you can add a signature in your profile.
       
      Signature.mov
       
      Follow the rules.
       
      Signatures, Avatars and Nicks
       
      Keep your signature/avatar clean and tidy - should you receive a PM from the staff regarding your signature/avatar, please make the requested alterations or it may be removed/shortened appropriately.
      To keep pages loading fast for everyone, we request that your signatures and avatars contain no animations or high-definition graphics of any kind.
      Signatures should be no more than 6 lines of text using a regular font. If you can't fit all of your system specs in that you'd like, why not create a small graphic to contain the information?

      hi there, 
      when attempting install 10.10 to my old PC, it reboots everytime when attached pic shows up. my hardware is:
      mb - unika p35 (with ich9) 775pin
      cpu - intel xeon x3210
      video card - nv geforce 8600gt
       
      could anybody know what was wrong? or is it possibly because of the video card, or the powermanagement?
       
      thank you so much for help!

      Hi   Clover limits the number of gpus to 4 :   from Clover source code : rEFIt_UEFI/Platform/Settings.c :   GFX_PROPERTIES                  gGraphics[4]; //no more then 4 graphics cards   Anybody knows why?   This number is limiting for me : - 1x gpu is AMD display GPU - 1x gpu is Supermicro's built-in vga IKVM output (Matrox 0x532102B)  
      - 3x gpus Nvidia for Cuda   I At present, I have to take off one Nvidia (but I'm trying to disable the build-in vga IKVM output through software, so that it's available for other operating systems : I'll make another post on that topic, to keep things clean)

      Hi!
       
      I’m starting a designing course and I’ve been told a Macbook is the best option to handle specific softwares like adobe Photoshop perfectly.
      Right now, i’m studying in Lisbon, Portugal. So, I would need to buy it from some Portuguese store, in case I need to claim warranty.
      Anyway, I started my search and found som results, fort some Portuguese stores , i’ll leave a link below.
      I'm aware that a desktops like a Mac Pro would be a much suitable solution, but I need a laptop to take to classes.
      I think a 13” Model is enough since the retina screen helps me see details better, but I don’t understand the software requirements for each type of software.
      What do you guys think I sould buy?
      Feel free to make any question or suggestion!

      i have ended up getting high sierra installed on my intel DQ670w board. i used a premade high sierra/clover dmg i extracted to a usb flash drive. right now the audio, networking arnt working and the video card i have in the machine an nvidia geforce 1050 gtx ti it works but has very very very choppy/jittery video. i did find some kext files for the network and audio but when i put them in the extensions folder they didnt do anything to add audio or networking. also i have to get the machine to boot from the hard drive rather then having to boot the usb flash drive to get the hard drive to boot and i have to work on the video card stuff as well. i am not to good at this stuff cause usually when i have tried stuff i end up breaking stuff or that stuff doesnt work. i am not all that code or certain tech savy. i am not the brightest. i like things laid out where its all like this is the files and where you get them from this is how u work with them kind of thing. it does agravate me when people just wont lay out stuff as like a dummy book does and makes everything easy. i tried on facebook groups and got as far as to be told what kexts to find but never told where to find them. i did try to look on my own and i did find a few kexts but they where ones that needed alterations to the os to even make them usable. the video kext or driver i was told to install it and do something like change something to true. all i need are the kext files and to make the machine boot from the hard drive rather then complaining it doesnt have an os on the drive or having to use the usb flash drive to make it boot and the video files and to know how to deal with the files and make them work without having to start over with everything and reinstalling stuff
