No GPU Power Managment

[GinoTheCop]

I followed the instructions and I can not use preview any more. In finder the pic files won't show and when I open a picture file with preview this is what I see;



GPU is at low clocks and Photoshop seems to work fine..

Update; After the boot and using the pc for a while, i wanted to reboot, and safari gave an error, then it didn't boot back. Had to login in single user mode and manually revert back to original OpenCl file or else the system would not boot. So make sure you have a backup before you attempt.

My GTX 570 is working perfect since 10.9.2 without OpenCL Fixes what so ever only edited AppleGraphicsPowerManagement.kext:

I changed my smbios.plist to Macpro5,1 and deleted the appletymcedriver.kext in /System/Library/Extensions/ otherwise i got an Kernel Panic at boot.

 

[lucalang]

can you explain me how solve with my gtx 760?

 

[Steiner]

You need to know your Power States and Thresholds, and of course your Device ID. If you know that you can follow my guide.

Your Device id is 1187 but i have no idea with the states and thresholds

 

[lucalang]

Where can i find Power States and Thresholds for my GC?

 

[Steiner]

no idea, i found my on google

but you can try my exact edits with your device id, maybe this will work. But don't forget to save your ApplePowerManagement.kext to a save place.

Change bot Vendor10deDevice1081 to Vendor10deDevice1187

Change bot Vendor10deDevice1081 to Vendor10deDevice1187

Be careful; Fermi use thresholds and Kepler uses P states. If you don't know the difference, default is better than wrong.

Here, 10.9.2 didn't change anything.
gtx 660 Gigabyte overclocked
I even tried editing agpm, which does not have anything to do with opencl and preview.app which causes the 1.03ghz

So, after all those updates (OSX, nVidia, Cuda, ect.), has anyone managed to get the frequency-bug of our kepler-cards out of our hackintoshes ? I mean, i tried every possible combination, but never was able to get a proper power management.
At least, my way of getting rid of it was the OpenCL-Fix (by macandor). With 10.9.2, i am having no issues so far, everything is smooth. I don't have the new nvidia drivers, becuase after the OpenCL-Fix i cannot install them !

 

[MysticalOS]

Do you really want to slow down your system by crippling opencl to work off cpu only just to fix power management? 10.9 uses opencl in a lot of places and anything offloaded to GPU is a good thing. It doesn't really bother me at all that my GPU stays ramped up if it means working OpenCL on that gpu. I have 2 extra case fans on gpu anyways and it stays at 40C. It'd be nice if apple/nvidia would fix the bug, sure, but gutting opencl to "fix" it doesn't seem like ideal solution to me. Although maybe that just depends on how much opencl your apps use. I certainly wouldn't gut opencl if you use any pro apps though. If you do not use any pro apps, then all you might suffer is slightly slower preview/quicklook or other minor opencl things.
