I bought myself one of these Sapphire Radeon HD 6870s a couple weeks ago for my new hackintosh. When I first booted it using the “GraphicsEnabler”=”Yes” flag in Chameleon, it booted fine and recognized the card as a 6870 in System Profiler but only one monitor worked. I disabled GraphicsEnabler and rebooted, and surprisingly it worked perfectly without any hacks. It shows up as “ATI Radeon 6xxx 1024MB” in System Profiler, but dual monitors are supported and all ports work. Unfortunately I couldn’t get 3 monitors to work, which was the main reason I went with an ATI card over an Nvidia card. That seems to be an issue with either the card itself or the DisplayPort to DVI cable I’m using, not with OS X because it’s the same in Windows 7. I definitely recommend this card if you’re building a hackintosh, it performs well and works right out of the box.
You need an active HDMI to Display Port Adapter to get the Monitor 3 and 4 working properly!
BR, derpuma
I think you’ll find also that with GE=no, as no real frame buffer is not loaded some apps like the DVD player, Ableton Live etc will crash.
Did you get your third monitor to work ? I’m trying the same here but no success.
just installed the latest chameleon, but nothing.
No I gave up on it. I think I read somewhere that the HDMI port is connected directly to one of the DVI ports so if you’re using both DVI ports and the HDMI port that could be the problem.
I havent been able to get dual monitor working with one connected to dvi and the other to the other dvi but with a dvi to vga adapter. Its only displaying through the port with the adapter.
Any ideas?
Do you have GraphicsEnabler set to yes? On mine if I do that only one DVI port works.
One thing that I found with my cards is use a gigabyte card instead on a sapphire one. I found this out the hard way. As an alternative, try getting a real AMD one. That worked with me too.
