Mela quadrata Posted November 3, 2014 Share Posted November 3, 2014 Hi, when my GPU pstates change from a state to another one, I have a flickering in my lcd similar to this video with a real macbook: My nvidia geforce 9800m GTS works perfectly, using all pstates of 168mhz, 275mhz ,400 mhz and 600 mhz, but, every time they move from a state to another, the flickering appears... Could you help me? Does it's an issue in the agpm configuration? (With Windows all works good) Any help will be appreciated, thank's in advanced Link to comment Share on other sites More sharing options...

Mela quadrata Posted November 8, 2014 Author Share Posted November 8, 2014 Have you modiefied your AGPM? Or is it vanilla? I use dsdt.aml patched for my nvidia 9800m GTS, that it's recognized as GFX0... Into my Smbios plist I use macbookpro 5,1 and into the file info.plist of AppleGraphicPowerManager.kext, at the voice machines/mabookpro5.1, there is GFX0 agpm configuration... When I use the notebook with powersupply, the minimum frequence remains only of 400mhz so the flickering will be only if the GPU change to the maximum of 600mhz If I unplug the powersupply, the GPU works with all frequency, 168mhz, 275mhz, 400 mhz, 600mhz; So the flickering is most frequent and very annoyng... (Istat menù show me that also gpu's memories frequency change) If I connect the notebook to an external monitor, the gpu stops the frequency frozen to the maximum of 600 mhz and max memory of 799mhz, so I never have the flickering... I attach my IoReg: IoReg.zip Link to comment Share on other sites More sharing options...
aphioner Posted November 8, 2014 Share Posted November 8, 2014 I see that you're using Graphics Enabler? If that's right, try to boot without it. Or vice versa. And then we'll figure out something else. Link to comment Share on other sites More sharing options...

And then we'll figure out something else. No i'dont... My Nvidia is enabled directly by dsdt.aml... However I've tried also without dsdt and with graphic enabler but it's the same problem... I also installed nvidia web driver, but the issue remains... It's very frustrating when I've to use the notebook in battery mode without external monitor Link to comment Share on other sites More sharing options...
Mela quadrata Posted November 10, 2014 Author Share Posted November 10, 2014 @ aphioner No idea?!? No one knows how to fix it? It's never happened to anyone this problem?!? And yet, if you search for "flickering" on the net, jump out many similar cases even on the original MacBook ... Link to comment Share on other sites More sharing options...
Mela quadrata Posted November 13, 2014 Author Share Posted November 13, 2014 I made other tests with AGPM ... if I remove completely agpm.kext, all frequencies work anyway ... This leaves me to think that the frequency management and probably what causes the flicker occurs elsewhere, in some other kext ... However, it may depend on what you need to make some changes in the dsdt.aml? As mentioned, also removing my dsdt.aml and starting with graphic enabler = Yes, the flicker is still ...

Mela quadrata Posted November 15, 2014 Author Share Posted November 15, 2014 Meanwhile, look at what Apple had released for laptops MacBookPro 5.1 with a 15 "screen (characteristics of all very close to my hack): http://support.apple.com/kb/DL1502 the efi firmware apple is going to be installed in the folder: System/Library/CoreServices/firmware Updates So the flickering was a real problem of the software respect macbook hardware close to mine... So, I also tried different profiles of macbook pro once since the patch was specifically referring to macbookpro5,1 (the profile which I use) ...Even with different profiles, flickering persists... I also read this: http://www.hackintoshosx.com/topic/20867-intel-hd-4600-flickering/?do=findComment&comment=104037 Now, on the basis of the above, kindly ask you "how pulling from Windows, the Edid, and then how I inject it in OS X?" the info about my monitor (taken on Windows 8.1 by Aida64) are these: --------[ Monitor ]----------- [Quanta QD15AL022 ] Monitor Properties: Monitor Name Quanta QD15AL022 Monitor ID QDS003E Manufacturer QUANTADISPLAY Model QD15AL022 Monitor Type 15" LCD (WSXGA+) Manufacture Date 2005 Serial Number None Max.
