ATI Graphic Issues on AMD ML Hackintosh Systems

193 posts in this topic

Recommended Posts

Rite since Great Work has been done by all the Devs on the new Legacy Kernel theres still a few Bugs to be taken care of on Phenom and Athlon Systems to get QE/CI in all his beauty running

 

Since the 1st Kernel has been released were still suffering from GUI Problems -> http://cl.ly/image/1G3V3I3s3k0Q

 

This Thread is to discuss and keep the Nvidia one clean from us buggin in

 

Post your Test and Workarounds ,your Cards and Thoughts on how to solve it

 

In my case a 5770 Batmobile will add some Picture later on

:wink2:

HD5870 here, using Andy's latest amd_kernels the glitches disappear in about 30 minutes. However, the system is not nice to use as long as the glitches appear there.

Also, the one when dock is shown from the "hide-mode" doesn't disappear. The dock just flashes for about a second and then acts as normal. :)

With my 6570 they go away with time. Some have found that deflecting the QE/CI kexts for your card may help.

So, i am trying the whole afternoon to get a step further, and maybe i did.

 

Until now i booted my system with GraphicsEnabler=No. My graphics card (hd5670) was detected as Radeon 5000 series.

 

When i tried to boot with GraphicsEnabler=Yes i got a panic in ATI5000Controller.kext. But when i ad AtiConfig=Hoolock, the system boots up and my card is detected as 5600 series. I tried Langur so far but it ended in a black screen. But i still have glitches and artifacts.

 

wastez, i think you tried different framebuffers. What was your experience?

 

Now i'm gonna try some different framebuffers and maybe some other smios.plist. This has to work somehow :D .

other framebuffers will give you most likely no ouput on your videoport ....

and other mac model neither since they not affect ATI Cards as much they do to nvidias

I think there is nothing we can do. I gues the kexts are using a instruction set which is not supported by the Kernel or something else.

So if no Developer help we will not get it working.

@spakk:

 

the problem is not the graphics card itself. in the video the dude is installing mountain lion on an intel cpu. so as andy says, its a problem with the delaytime the ssse3-emulator introduces. on intel and bulldozer etc. cpu's you have native ssse3 ;).

 

and in german ;)

 

das problem ist nicht die grafikkarte. in dem video installiert der kerl mountain lion auf einer intel cpu. andy sagt, dass es ein problem mit der verzögerung gibt, welche vom ssse3 emulator kommt. intel und bulldozer etc. können ja nativ ssse3... von daher gibt es hier keine verzögerung ;)

since some real mac users flashed there ATI Cards with lower clock settings to get rid of glitches

 

why dont we drop a rom with lower settings and try booting with that

 

could that work ? to reach the same effect ?

Yes, it could work.

Also it will give the opemu more time.

hmm, they increased clock setting. my card also hat about 150mhz gpu/ 200mhz ram clock setting in power save mode. they suggested that you increase the settings to about 400/1000. it's more about deactivating the power-saving modes. for my card it didn't work, but there are a lot of mac people where that didn't work either. still has the feeling that this is a "mac" problem. but if someone would try to edit his graphics bios, i could give help.... did this yesterday all day long :D... so i gained a little experience here. but if you could just do this with a rom......

 

but all the different ati-cards have other roms.... so one had to offer more roms for the different ati cards out there, or am i wrong?

So, underclocking GPU could work? :D

I could try with my old HD4650, if I can find it and the machine agrees to boot. :)

Are we sure this isn't something opengl related? When I compare my 4870 (only glitches in chrome with flash as far as I know) and my 5450 (lots of glitches in safari etc).

The 4870 is way faster (more shader units, higher clockrate), so for me it's hard to believe this is speed related.

 

So I looked up some specifications, these below stood out as the only difference in capabilities (besides raw power of course).


         4870      5450
OpenGL version      3.0      3.2
Shader Model      4.1      5.0

I think this could be the problem!

Is it true that HD5770 is woring OOB?

Because my little brother has graphic issues on that one to.

-About my HD6770 , after reinstalling with another installdisk i also have issues -

yes that is true and your 6770 is Chipwise the same aswell AFAIK

 

 

wastez and myself tested with underclocked roms for 5770 without alot of changes in glitches /artifacts

 

so i guess that is a dead end .....

 

investigate more

 

Andy could u have a look inside the AMDRadeon kexts for any clue if you have a minute these days
