xympa Posted October 21, 2011 Share Posted October 21, 2011 My HD 5870 is only showing 8x PCiE, and it's connected to a 16x slot, It's also showing some lag while browsing inside steam. I haven't played any games yet, so i can't speak of the acceleration... Do I need a special Kext? I was under the impression that these Atis were natively supported since 10.6.5...

I used this tutorial, I'm not sure what version of chameleon I'm using, but I'll let you know as soon as get a chance to reboot. UPDATE: I'm using Chameleon 2.1 r1627 UPDATE 2: Nevermind, i guess my mobo is going awire, I switched to the second pcie slot and it's working fine...
