ASUS nVidia Geforce 660 GTX problem

[kgariba]

Hello everyone,

I just replaced a BFG Geforce GTX 280 that was working very well with a new ASUS Geforce GTX 660 on my system. Previously it worked very well and was stable with mountain lion (minus inability to wake from sleep and occasional inability to shut down). I have a dual boot with Win 7 and everything works well on it (so I know the card is fine) but once I tried the mac boot, the boot stops at the gray screen (that normally shows right before it shows the desktop) and... that's it. I tried rebooting (because sometimes that would do the trick) but nada. Any advice on how to fix this would be great (i.e. how to update the drivers). I haven't touched my hackintosh set up in a while so I am kinda rusty on what I should do first. Thank you all very much.

Here's the rest of my set up:

Asus P6T Deluxw V2 MB
Antec 750W PSU
Intel i7 920 2.97 Ghz CPU
G.skill 12GB RAM
WD 500 GB HD (with ML)

Any help would be appreciated.

You need to use GraphicsEnabler=No and the 660 also needed the nvidia drivers installed before 10.8.3. After 10.8.3 660 worked OOB with GraphicsEnabler=No

That fixed it! Thank you! Worked out of the box after switching Graphics Enabler to 'No'.
