Mr. Hackintosh Posted September 12, 2013 Share Posted September 12, 2013 Hello everyone! Posting here to see if I can get some help with this issue I am having. First off let me tell you a bit about my computer: Motherboard is a Gigabyte Z68XP-UD4 with BIOS F6 Graphics card is an ASUS Geforce GTX 560Ti Top (Direct CU II) Device ID: 10de1200 Operating system is 10.8.4 installed using latest MyHack. Used a certain post-install tool with DSDT install and added sound and networking drivers from there. Using a System profile MacPro 5,1. with the Nvidia web drivers (running off the OSX default driver) Now, everything works just like I want it to except for the power management for the graphics card. When under OS X the GPU fan spins faster and faster as the card gets warmer and warmer even on idle. I found some tutorial on how to edit the kext to have the power consumption/heat/fan speed reduced to work about the same as it does in Windows (very quiet on idle - and cool) BUT... Whenever I make the edits to the AppleGraphicsPowerManagement.kext... when I boot in verbose mode I DO see that it does recognize the card and fires up power management for it but for some reason the screens (I have two) goes black.... If I put back the original unedited kext then it starts fine again, but then the graphics card gets very warm!! Any help with how to fix this would be very much appreciated. Is there anyone out there with my kind of graphics card that has gotten it to work? I did try to put a posting on "that other hackintosh forum" but not feeling any love there so that's why I'm turning to you guys here hoping I can get help in resolving this issue... Thank you very much for your time and I hope for some help in solving this issue. //Mr_Hackintosh Link to comment Share on other sites More sharing options...
