travis134 Posted June 16, 2010 Share Posted June 16, 2010 Hello there! I recently built a machine and posted the hardware I used quite awhile ago. Everything worked fine in regards to installing OSX, however my resolutions were {censored} as a result of using an unsupported video card, the ATI 5850 Recently I purchased a supported card, an EVGA Nvidia 8800 GT with 512mb Vram I have installed the new graphics card and I have successfully made Windows ignore it (My windows OS is for gaming, so I ignore the 8800 GT so I can use my monster 5850) I want to know how I can do this with Mac OS X. Basically here's my problem: I used the following tutorial to install OS X http://tonymacx86.blogspot.com/2010/04/ibo...ac-os-x-on.html Everything works fine when I have only the 8800 GT plugged in, however when I have both video cards in, and attempt to boot to OS X my fan on my NVidia 8800 GT maxes out; it sounds very bad, then nothing happens. Am I doing something wrong? Is my setup impossible? Thank you! Link to comment Share on other sites More sharing options...
Alessandro17 Posted June 17, 2010 Share Posted June 17, 2010 Is my setup impossible? That is good question! Having OS X working on a PC is a small miracle on itself. Expecting that it works with 2 totally different cards is way too much. Link to comment Share on other sites More sharing options...
