ATI/AMD 5xxx 6xxx 7xxx 2xx 3xx Graphics Cards Framebuffer Personalities

Any advantages in terms of performance running a specific framebuffer rather then none? i have a gigabyte r9 280x runs good so far without issues but reads as a radeaon 7**
Massive difference in speed.

P.S.
Speed wise there seems not really a difference between Radeon and Baladi for me at least.

I'm in the same boat with a dual 280x setup. Have you done anything about changing your card names/IDs on your Hackintosh?
 
If I did not inject a frame buffer, how can I determine which frame buffer was used by default? kextstat?
 
Hello Tonymacx86
I need a little help with my Ati/Radeon HD 6670 and 6450 cards. I was able to get them to boot up and they are working but my issue is they are flickering in and out like it trying to work like the color gets throwed off. Is there a fix for this i have used IOReg to look up the names (Gibba,Lotus,Muskgrass) and i am only using the HDMI on each one. Thanks for your help in advance.
 
Hi Guys! I'm trying to make a build with 2x Radeon HD5850's. Would be anybody that kind and make a step by step guide for a noob? (this is my very first built) I read the topic starter but don't really get where, how and what should I insert/write. In the clover bootloader I found the gpu section where I can check the injection and I also filled the GPU ID (that 0x68991002) but I do not know what else and how should be filled, or if it is necessary or maybe better some fully other way.
Currently I'm always stuck at the half of the installation the part of sierra is already on the SSD, but when the restart comes, it still boots from the USB, and if choose the bootloader to boot from SSD it stucks/restarts
currently I got this errors in verbose mode (see attached picture).
The MoBo is a GA-Z170x-Designare (bios F2... should I update, or better to not?)

Can anybody help pls?

How can I look up the best framebuffer and device configuration for a ATI Radeon HD 6470m in Sierra? Do I need to change these values in the config.plist, as well clover boot screen, as well in the 6000 controller kext itself, so guidance would be great. I'm trying to enable the AMD6000 controller kext to see the video card. I also assume you have to modify the device ID+ FB name the config.plist in the EFI, as well in the info.plist on the 6000 kext itself?

Thank You
 
Can someone please help me with my Radeon HD6450?

I can‘t see the UniBeast Installer Screen. Its flickering two times after its halfway through the apple logo and bar and then its going to sleep or whatever it does. I‘m down to this framebuffer thing but nothing works.
 
Good Morning!
I have the same problem.
Worse, I have a R7 240 2GB and I wanted to activate the mojave and catalina and I can't.

If I managed to activate these two, I would have two good hackintosh here!
