Radeon HD 6770 full QE/CI! (Mountain Lion)

[Rickondrius]

Greetings!

As most of you know, the Radeon HD 6770 is not supported by Macs and you HAVE to flash your cards BIOS to that of the Radeon HD 5770.

So I came up with a final solution to this, and save the worries of flashing your 6770, losing your warranty and possibly leaving your card unusable. Check out the link below:

Here's a pic for reference:

Tested on an XFX Radeon HD 6770 850M 1 GB GDDR5, VGA and DVI work perfectly fine. Not sure about HDMI.

By the way, games run perfectly smooth, I tested it with Starcraft II at Ultra settings 1366x768.

Note: you must be running the latest version Chameleon/Chimera for it to work. Also you must boot with GraphicsEnabler=Yes.

Enjoy!

Worked for me in a Gigabyte HD6770, but two issues:
1- Geekbench have down aprox to the half compared to my old card, Geforce 210 (512 mb, DDR2)
2- Dual monitor does not work, only mirrored mode

I need to use 2 monitors, so if there is no solution for that unfortunatelly I will need to downgrade to my old Geforce 210 (512 mb, DDR2)that allows dual monitor or think about the flashing to 5770.

Any update on dual monitor compatibility? I am currently looking into installing a 6770 in my Mountain lion rig. I have two monitors that i use without mirroring... is there a fix for this with the 6770 yet? i am trying to avoid flashing to 5770. if you ended up flashing please describe any things to watch out for. thanks!

Hi

I got a XFX 6770 card. I tried the linked updated Kexts. Edited the com.apple.Boot.plist. Always hangs.

Flashes the graphics screen then I see stuff about trying to load my ntfs drives.

I've tried Aticonfig of Vervet and Pithecia
GraphicsEnabler = Yes

Thing is when I boot into safemode, I get a 1920x1200 resolution and the systemreport reports that I have an ATI Radeon 5000


its not a big deal that it sees it as a 5000, I just want to be able to boot without safe mode...

any ideas?

edit: turns out to be the ATI5000 kext giving me issues...

What did you edit in the 5000 kext to make it work ? Any help would be appreciated.
