A Question About DSDT
2 2

Question

I don't need DSDT for my hardware, but I am having some problems with my graphics.  I read somewhere that I just need to set something up in DSDT to fix it.  I'm just wondering if I can use DSDT even though my hardware doesn't require it.

Depend Upon What Hardware you have ?? like latest Intel 8 series chipset's with UEFI Bios don't required any DSDT ,,for Last or Older Chispets required DSDT you Mac OS X working properly ...post your system Specs ...i'll check out you need or don't ..

ASUS M5A99FX PRO R2.0  Mobo

AMD FX 8320  8-Core Black Edition 3.5GHz  Processor

Radeon HD 7770 Core Edition  Graphics

32Gb DDR3  Ram

 

Everything seems to be working fine except for the fact that my graphics card is running like it 15 years old.  Desktop and normal programs work but I can't watch youtube or any other web pages that use flash, even switching to the launch pad or mission control is slow and laggy.  Almost like I don't have any video ram.

Any idea how I could fully enable QE/CE?  I'm new to Mac and Hackintosh so I'm learning as I go.  I'v found a few things on the web that said I need to edit something and add the vender id and product id.  I found those id's but not sure what to do with them now.  Any help would be appreciated.

Download EFIStudio and Chameleon Wizard

 

And get your GPU STRING using the above mentioned software.

 

Copy this STRING.

 

Open Chameleon Wizard and goto "2nd TAB" aka chameleon boot plist.

 

In left-down side where it says device ID, paste your string into the box and hit apply.

 

Reboot.

EFIStudio doesn't have my video card in the list. I figured out from searching the net that the vender and product ID's are 683D 1002. It's a Radeon HD 7770  1024Mb card.

 Radeon HD 7770 cards requires GraphicsEnabler=No ,,make sure you have radeon Kexts installed sometimes those are missing 

 

use below command check you have kext or not 

Type in terminal:
kextstat | grep ATI
and once
kextstat | grep ATI

Output should be:


com.apple.kext.ATISupport (8.1.4) <65 10 9 7 5 4 3 1>
com.apple.kext.ATI7000Controller (8.1.4) <87 65 10 9 5 4 3 1>
com.apple.AMDRadeonAccelerator (1.0.8) <89 66 65 10 7 5 4 3 1>
com.apple.kext.ATIFramebuffer (8.1.4) <87 65 10 9 7 5 4 3 1>

I tried what you said;

 

Type in terminal:

kextstat | grep ATI
and once
kextstat
| grep ATI

 
Nothing happens. It just keeps going back to the command prompt.  I downloaded and installed the files for my card from the 'Downloads' section from here.
But no difference.
 
When I go to System Information utility and Graphics/Display, this is what it tells me:
 

Display:

 

  Type: GPU

  Bus: PCIe

  PCIe Lane Width: x16

  VRAM (Total): 7 MB

  Vendor: ATI (0x1002)

  Device ID: 0x683d

  Revision ID: 0x0000

  Kernel Extension Info: No Kext Loaded

  Displays:

Display:

  Resolution: 1920 x 1080

  Pixel Depth: 32-Bit Color (ARGB8888)

  Main Display: Yes

  Mirror: Off

  Online: Yes

 

My card has 1024 MB  not 7 MB
