EVGA GTX 660 Ti SC (3GB) Problem with Mountain Lion

[liquidblood]

Did it! I just replaced ONLY the "OpenCL" file! Thanks a lot friend! Works now!

My EVGA GTX660 Ti 3GB just arrive today and Im having the same problem, can you help me, Im just a noob in the hackintosh world, so, where can I get the opencl file thanks

Ok! Go to SYSTEM folder, open LIBRARY folder and then you will find a folder called FRAMEWORKS. In there you will find a folder called "OpenCL. framework". Then follow this trail of actions: OpenCL.framework/Versions/A/OpenCL

Once you find the OpenCL file, you need to edit it with a hex editor, such as Hex Fiend. Open it with Hex Fiend and you have to do these:

1) for 32-bit part:
find 3d 01 00 00 80 73 e7
replace with 3d 01 00 00 80 90 90
yes, its just last two bytes to disable the check

2) for 64-bit part, for lion
find ff 50 68 48 39 d8 73 e5
replace with ff 50 68 48 39 d8 90 90

for mountain lion
find ff 50 68 4c 39 e0 73 e7
replace with ff 50 68 4c 39 e0 90 90
P.S. doesnt applies to gtx670/gtx680, they have a different problem

Its working now my score in ocean wave was a little disappointing 332.7 Luxmark 1095 behind the GTX 580 but at least it works. I installed the OpenCL fermi patch rebooted and then installed the GTX 6xx support I saw this method in another forum I don't remember where but thank you and thanks to the person who made that post I do whant to ask a question what ID are you using in SMbios ?

 

[Gatsouni]

Glad to hear that it worked, the ID is the default Nvidia: 0x10DE

Thank you for the reply but what I meant was what Mac Id (Macpro 3,1 imac 12,2 etc)

Personally I use, "iMac12,2", it is compatible with my Asus P8P67 Pro B3 motherboard, actually it is the only ID that works perfectly with this specific MB.
