Enable Hardware Acceleration for HD 6950 (Mountain Lion)

23 posts in this topic

Recommended Posts

Hi! Mountain Lion works well and recognizes my Sapphire HD 6950 2GB (full 1080p) but how can I enable hardware acceleration?

For example: without hardware acceleration the LaunchPad and a lot of app are too slow...help me! thanks a lot!

@figarotheall:

update: OS X 10.8

 

introduction of new kext:

 

AMDRadeonAccelerator.kext

 

that will replace the ATIRadeonx3000

 

In 10.8, I don't think it uses X3000 anymore. Try and edit info.plist of x3000 and amdradeonaclerator.kext then try booting with and without it.

No. I've tried edited AMdRadeonAccelerator.kext but it still given a white screen.

And ATIX3000.kext already has 6719-1002 in it if you look hard enough ( or search? ).

Still a no-go for acceleration for 6950 on 10.8

I had issues with white screens and garbled graphics on my Ati card in Mountain Lion too.

 

I "fixed" it by using the AtiController, AtiFramebuffer and AtiSupport kexts from Lion (make sure you aren't using the AtiX3000 kexts) and the AMD kexts from Mountain Lion. You may also need to pass in the correct AtiConfig and AtiPorts for your card in org.chameleon.boot.plist, if Chameleon doesn't automatically pick the right ones for you.

@manor

 

Thank you very much for sharing you 6950 files with us.

 

I have a question concerning the DSDT's do we need them all installed? How do we that the best way?

 

install kexts via kext wizard

and edit graphics to your dsdt.

set bios intit

then restart -v

 

Enable whitescreen

You have to use Mini DisplayPort Male to DVI-D Dual Link Female Premium Adapter

you need another Graphics Card to get 6950 work

I tried nvidia card @ 1 slot and 6950 @ 2nd slot but the two video cards are recognized as multi-monitor, in fact the main desktop is shown by the nvidia card and AMD card simply shows an empty desktop, so if I unplug the nvidia, I have only an empty desktop without hardware acceleration....You should find another method that works with only my HD 6950...with two card it doesn't work. :wallbash:

if you see cursor with gray screen.. press power button to goto sleep and press again to come back. u might get desktop. if u dont then ur kext aren't loaded properly or incorrect ones. i can get 6950 working with full resolution just no acceleration. which makes it useless pretty much.
