Steiner Posted March 2, 2012 Share Posted March 2, 2012 Hi, i have a realy strange problem with my Gainward GTX 570 Phantom. When i start my hackintosh i have very low frames in different benchmarks like OpenGL Extension Viewer, Cinebench. Even the launchpad is glitchy. The strange thing is if the monitor goes into sleep mode and comes back out, everything works perfect. Then each benchmark runs as it should. THIS WORKS ONLY WITH smbios.plist Mac Pro3.1 from ######. With all other smbios.plist Versions nothing happens after the monitor suspend. Always low frames an lags every minute or so. My specs: Board: asRock z68 pro3 CPU: i5-2500k GFX: Gainward GTX 570 Phantom I have captured my screen with my smartphone, so you can see what i mean. http://www.youtube.com/watch?v=KgKkV9_OxiE I hope someone can help greets Marco Link to comment https://www.insanelymac.com/forum/topic/276660-gtx-570-strange-problem/ Share on other sites More sharing options...

Delete the AppleGraphicsPowerManagement.kext and rebuild caches Link to comment https://www.insanelymac.com/forum/topic/276660-gtx-570-strange-problem/#findComment-1802449 Share on other sites More sharing options...
mitch_de Posted March 4, 2012 Share Posted March 4, 2012 Yep, fore sure an AGPM (gpu powermanagement problem). You also can look at the AGPM thread in the Nvidia GPU forum here.

iLeopod Posted March 4, 2012 Share Posted March 4, 2012 Have the same problem, even with custom agpm or with deleted agpm.kext. Maybe the custom pcb or the frequencies are a problem. Try these drivers: http://www.nvidia.com/object/macosx-270.00.00f01-driver.html Pros: -no need to add ids - around 5k fps before sleep cycle and after around 7 k fps with opengl 2.x Link to comment https://www.insanelymac.com/forum/topic/276660-gtx-570-strange-problem/#findComment-1803038 Share on other sites More sharing options...
