NicolBolas Posted March 20, 2007 Share Posted March 20, 2007 Hi everyone ! I'm looking for any feedback/try/hint/tutorial, well, any information you may have about having multiple video cards in a homebrew mac. I'm not talking about SLI / CrossFire, those have already been talked about and are not supported afaik. For now, I'm willing to use 2 PCIe videocards on my Asrock Conroe XFire-eSataII mainboard. I already have a GF7600GT up and running with 2 19" CRT displays. I also tried a bunch of nvidia cards (6200, 6600, 7300GT, 7600GS), all work fine with QE/CI. I had some BIOS glitches at my first tries but I can now boot Linux with 2 video cards plugged in (7600GT and 7300GT). Mac OS can't boot with that : it freeze quite soon in the boot process (didn't check the verbose messages yet). Is there any way to get this working? The MacPro _can_ drive up to 8 screens with 4 7300GT installed, may a hackintosh do it as well? I'm considering any option : identical video cards, alternative mainboard, mixed nVidia / ATI boards, well, anything that could lead to have 4 screens with QE/CI running. Any help would be greatly appreciated, and thanks for reading this, now be thanked twice for posting any information you may have ! best regards, Jerome Link to comment https://www.insanelymac.com/forum/topic/45810-how-to-use-multiple-video-cards-eg-triple-quad-screen/ Share on other sites More sharing options...
BCrowie Posted August 23, 2007 Share Posted August 23, 2007 I am interested in this as well. Does anyone have a clue on how to get four displays running at once?

cubswinfllclssic Posted August 23, 2007 Share Posted August 23, 2007 I was interested in this awhile back as well, but I had no luck. Real Macs support as many displays as you have PCI video cards, but I tried adding a low-end PCI card to my already dual-monitor AGP setup, and the system crashed on boot. My only thought was to buy an old(er) PCI ATI gfx card that's Mac-compatible (there are a couple on ebay) and to see if using that alongside an AGP or PCIe configuration might work. Has anybody tried that?

A "Mac Compatible" video card wont help. Mac video cards has a special firmware instead of the BIOS/VESA support, in order to be used as the machine's primary video adapter. Also, a mac compatible PCI card will have it's initialisation firmware built for PPC arch.

manmal Posted October 21, 2007 Share Posted October 21, 2007 so you say that there is no way to go triple head or quad head actually in any way on hackintoshes?
