No GPU Power Managment

[m4rkus95]

Second this! I am running on a gtx 760 and clock run up and down like they should. (especially when using quicklook and preview for pictures)

The fix worked for my MSI GTX 760 on 10.9.1 perfectly, too (which have the GK104 type like the GTX 670).
I tested it with Quicklook and Preview and the Freqs don't stuck at a high value; it go up and down like it should (see the screenshot).
I tested the power consumption of my whole system, too and it was around 65 Watts like in Windows 7. The temp of the GPU is around 29°C and the fans of the card is around 1020rpm in idyle.

Does 10.9.2 13C62 released today fix this?

No.

opencl still leaves card at full stock throttle. It's interesting that it leaves it at stock throttle though. My gpu sits at 979Mhz when full throttle is 1.1Ghz.

Personally this is a much better bug than the "B" card bug i spent months with. At least now GK110B are now right there with the "A" revs and earlier nvidia cards with the full throttle bug instead of crash bug That's once you take the opencl lib out of R331 package and replace the one in 10.9.2's geforceGL kext.

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.

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.
