No GPU Power Managment

[chevalier433]

Good to hear of a possible solution. Can anyone else verify that this works? I can't test it as I have HD3000. I wonder if that would work?

It should work for you too.

I have had my HD4000 enabled since ML. Power management still broke with my 660.

First go to your bios set IGPU as your primary graphics and shared memory to 64MB.
Finally in your org.chameleon.boot.plist bellow these lines <key>GraphicsEnabler</key>
<string>No</string >

inject

<key>Graphics Mode</key>
<string> 1920x1080x32</string>
<key>device-properties</key>
<string>7f0000000100000001000000730000000200000002010c00d041030a000000000101060000027fff04002c0000004100410050004c002c00690067002d0070006c006100740066006f0072006d002d006900640000000800000005006201140000006800640061002d0067006600780000000d0000006f6e626f6172642d31<string>

If you have a 1080p display.If not adjust your current resolution in line 2.


and voila! you have both GPU's working together and this ****ty bug disappear.Good luck!

Dude your iGPU is not identify properly.Look mine.

I have had my HD4000 enabled since ML. Power management still broke with my 660.

Maybe you think is enabled post a pic from about this mac.

660 and 4600 here

Without injecting anything both graphics have been recognized since I installed it the first time. Does it make a difference if I inject anything? Will it solve the clock problem? And how do I get the strings for my igpu?

Thanks in advance

Opening the attached pics makes my GPU clock up again...

Same here, gtx 760, intel 4600, both recognized, no injection, remains stuck, but noticed that the lower it starts its about 647 mhz since i enabled the intel.

I was able to duplicate the issues mentioned in the last couple of posts. I think it has something to do with:

<key>device-properties</key>
<string>7f0000000100000001000000730000000200000002 010c00d041030a000000000101060000027fff04002c000000 4100410050004c002c00690067002d0070006c006100740066 006f0072006d002d0069006400000008000000050062011400 00006800640061002d0067006600780000000d0000006f6e62 6f6172642d31<string>

As soon as I add this key to my org.chameleon.boot.plist the Intel HD 4600 is not recognised anymore. Maybe it will work if we get the string right for the Intel HD 4600.

@chevalier433 You are using an Intel HD 4000 correct? How did you find out the device property for that iGPU?

Dear friends i am not an experienced hackintosh user but i learn fast.I think the mistake you've done is that you have connect the monitor cable to your PCIe card connect it to your iGPU and i hope to resolve your problem to identify your igpu properly.Good luck everyone have an nice night and sorry for my english.

ΥΓ.If you connect it to igpu your both card will work just fine for example if you play games or adobe CS6 suite your pcie will identify and use as in my setup.
