ML: Native Ivy Bridge CPU and GPU Power Management

[NeXTguy]

-Opened AppleGraphicsPowerManagement.kext/Contents/Info.plist in Teksteditor
-Installed IOreg.expl. and opened in /././././AGPMController

Now what do I do next?
I'm pretty sure it has something to do with Vendor10deDevice1086

Maybe the two last bullet points of my post #573 in this thread help you. I have a discrete GPU but I do explain how to make the edits you're after. Wasn't obvious at first to me either.

Now what do I do next?

Nothing. No discrete graphics card, no AGPM edit required.

@ toleda and NeXTguy

Couldn't figure out how and what, so I decided to leave it, as it is working now.
By the way,
I connected my plasma (1024x768) with HDMI as extended desktop and ran some 1080p (I know, that's overdoing it) youtubes on it, and they ran beautyful.
HWmonitor shows spikes to max frequency, but the activity monitor graph stays between 10 and 20%. Or less!
(I mean CPU graphs; I don't have GPU in HWMonitor)

So I'm convinced it's working allright. Oh yes, 'the ripple' as well.
So thanks for the hints and tips guys!

HWMonitor is showing no GPU throttling, its all time at 723 MHz. When i edit the kext, i copy it on my workspace, edit it and copy it back. 5...6... seconds after that the system show a failer in a window... "....couldnt load kext". The System works after that still normal.

What do i wrong, please me help

Can't copy an edited kext into S/L/E with fixing permissions and cache. Use Downloads/Software/KextBeast to install an edited kext. You system is not working "normally" with this problem.

So now i downloaded Kextbeast and installed the edited applegprahicspowermanagement.kext. After that it comes the same failure, after reboot also....

"System extension can not be used. - ... Was installed improperly and can not be used. Install it again or ask the manufacturer ... "

I do something very very wrong... i installed no nVidia Drives, no other patches for OpenCL is this wrong ?

Thank you toledo for your help

Follow the directions, exactly.

Follow the directions, exactly.

Have installed the System complete new, new multibeast, then GPU runs only with 405 MHz.

Then set system definiton to MacMini 6.1 and edited AppleGraphicsPowerManagement.kext.

I deletet nothing in kext, i add the part for my graphics, then run Kexbeast and reboot.

NOW EVERYTHING WORKS, THX TOLEDA !!!!

Hi again guys, toleda, just one quick question, I have changed motherboards and instead of the h61m-d2h-usb3 I know have a series 7 z77-dsh3h after reading again the first post I am unsure wether I should use the ivy power management like I was using with my last series 6 board. I have an ivy bridge CPU with the hd2500. Can you or anyone else for that matter, shed some light on this?

Thanks in advance

Yes, PM is for the processor not the motherboard.
