AMD R9 290X on Yosemite

[juutsch]

The new 5K iMac has a R9 M290X in it. So has anyone checked out if there's a native support for the "new" R9 Cards in Yosemite?

M290X is Pitcairn, not the same chip as the Desktop R9 290X that has a Hawaii chip.

The M295X is a new product, but rumours suggest it is a new chip named Tonga (R9 285 on desktop).

Some people got 290X to work but there's still some framebuffer issues (no multi monitor support).

I hope that now with the official Yosemite release, more people will try to fix the framebuffer so that I can use my 290X on OSX

Despite sharing the R9 name, the AMD R9 series actually composes of many different GPU families with different architecture. The R9 M290X/M295X seems to be structually similar to the HD7950/7970 of yesteryear so maybe we can get them working. People have reported 290X working natively with Yosemite (I've seen a lot) and 290 working with some kext injection (less seen so I can't say for sure). Still there are problems with frame buffers, HDMI audio, multimonitor setup and sometimes OpenCL. But good luck getting 27x/28x cards to work, I have seen few that claim to work.
Meanwhile nVidia is doing a great job writing drivers for OS X recently (even their 9-series) so I guess I'll just stick with my GTX770 for now.

I'm running my 290x perfectly using clover. I gave up on chameleon because you get white jibberish on black text whichever way you try and boot with it. Clover on the other hand gave me 0 issues. Card is recognised as AMD 8xxx series.

Nice! How about a guide?

Have you tried dual screen?

I've got an R9 290, and I'm also using Clover with 10.10. I tested dual monitors (DVI and HDMI) and OpenCL (Luxmark Sala = 2488). No problems, except for one thing: when it first boots up, the screen flashes over and over, and I have to unplug the monitor connection for a sec to fix it!

I had a similar issue with my r9 290x where the screen was fuzzy and I had to unplug the monitor for a second also. I was able to get it fixed by setting my monitors resolution for the clover bootloader using clover configurator.

Hi,
Do you used some patched video kext, DSDT edit, or something for get it working, or just it's supported by default for Yosemite ?

I used a fakeid of 0x67B01002 for the "ATI" key of my config.plist. That way the card presents as a 290x and the correct kext will load without having to edit any Info.plist. As far as I can tell, once the kext is loaded it will actually talk to the card and find out that it is a 290, not a 290x.

OK, I will try it.

Many thanks!
