Vertiphon Posted December 17, 2007 Share Posted December 17, 2007 I have a PCI-E Geforce 6600 that I'm using in my hackintosh. Uphuck 10.4.9 installs just fine with it (P4 Northwood, SSE2), but I get blackouts whenever OS X tries to use the card's acceleration features: playing video, 3D effects etc. After a second the screen comes back for a moment, then it blacks out again. Once the video / 3D effect / etc stops, the blackouts stop. I get the same behaviour whether I use Titan or Natit drivers What is causing this? Edit: Solved. OS X just doesn't like the card. Replaced it. Link to comment Share on other sites More sharing options...
plprado Posted December 17, 2007 Share Posted December 17, 2007 I don´t know if this is the same issue you´re having, but this happens to my system when it overheats. With me it happens if I overcharge my cpu (using audio and Image programs at the sime time). Besides that, my case ventilation is far from good, that´s why I keep a big fan pointed to my cpu. Whenever it happens (usually when the weather is hot) I open the case and turn the fan on, and it stops right away. I know, this is very primitive, but it works...

Vertiphon Posted December 17, 2007 Author Share Posted December 17, 2007 Right, I should have mentioned that the same Geforce came from a PC where it worked flawlessly. I'm not overclocking my Hackintosh in any way, either. Link to comment Share on other sites More sharing options...
Vertiphon Posted December 17, 2007 Author Share Posted December 17, 2007 Okay, I've tried replacing the PSU, and that seemed to help for a while, but the blackouts came back. As luck would have it, I managed to get hold of a PCI-E Geforce 7300LE. Hardly a fast card, but it worked immediately and hasn't blacked out once. So perhaps OS X just doesn't like some cards: the 6600 I originally tried again is working fine in a PC. Odd. Link to comment Share on other sites More sharing options...
