thewierdone2000 Posted March 22, 2011 Share Posted March 22, 2011 Hey all, I know that OS X doesn't support SLI, however I dual boot my machine into windows 7 for some gaming. I am wondering whether a single graphics card will be recognized if I have the SLI bridge installed. ie. If I have two cards in SLI, when I boot into OS X, will it detect one of them as normal, or would I have to remove the SLI bridge? Specifically it is the GTX 460s that I am looking into doing this with. I've searched around a bit but couldn't find any real answer to this question. Thanks in advance!

kch0pa Posted March 22, 2011 Share Posted March 22, 2011 That will work. Only drawback is that there is no Fermi support in OSX, so GTX460's would not have QE/CI support.

Actually, nVidia released official support for the GTX 480 and subsequently the GTX 460 can work under it. It was a bit of a pain to setup (partially because of all the clean up required of the old drivers) but I was able to get it working by doing the following: 1. Remove nvenabler from /Extra 2. Install TonyMac modified nVidia Driver (This is same as stock, just modified to not check whether you're installing on MacPro or not. 3. Set your hackintosh to identify as 3,1 (or modify /System/Library/Extensions/AppleGraphicsPowerManagement Info.plist to have device ID of your device (0e22 for the GTX 460) under 4,1 or 5,1 (depending on what your mac identifies as...). This is to fix problems with the card not getting the juice it needs to run properly 4. Set up a custom EFI string in com.apple.Boot.plist (various guides can be found for this, I used OSx86Tools) 5. Reboot and hope! Worked for me. Anyway, thanks for the answer! Here's hoping it'll work in SLI.

Gringo Vermelho Posted March 22, 2011 Share Posted March 22, 2011 Chameleon 2.0 RC5 with GraphicsEnabler=y works fine as well and it's easier than installing injectors or making device-property strings. You'll need to start OS X with GraphicsEnabler=n until you install the nvidia drivers though. there is no Fermi support in OSX, so GTX460's would not have QE/CI support. Where have you been? Snow Leopard has had Fermi support for a whole year now. People have had QE/CI on GTX 480 cards since March 2010 in 10.6.4. Proof of upcoming Fermi support appeared in 10.6.3. http://www.insanelymac.com/forum/index.php?showtopic=214219 Link to comment https://www.insanelymac.com/forum/topic/252974-sli-card-configuration-possible/#findComment-1659330 Share on other sites More sharing options...

But whatever, I guess it does work indeed.

You must install the Quadro 4000 nvidia drivers to get Fermi support.

Sadly that didn't work for me when I tried it. I spent about a week futsing around with various ways of getting it to work, and the only thing I could do was device-property strings to make it work. Lots of people have reported success with that, so I think I'm an exception.

Gringo Vermelho Posted March 23, 2011 Share Posted March 23, 2011 Maybe you needed to set PCIRoot=1 in your /Extra/com.apple.Boot.plist for GraphicsEnabler to work. You can easily check that by looking at your device-properties string (from before hex conversion :-).

Tried that too Like I said, I tried every way of getting a graphics card to work that I know of (DSDT in addition to the already mentioned ways) and that was the only way that I could get it working.
