The power is not working correctly for the video card that is what I get if it is not working full power all the time to it the frequency and voltage to is is supposed to drop when it is working like I see with the frequency here I don't get voltages displayed. Thank you When I have mine connected to external display (only tested the VGA) it disables the laptop screen so I have never seen any lag like you describe, is this connected via the dvi port yours has? If so try vga to see if it helps. So it seems that Clover uses the correct settings, right? So depending on what HWMonitor shows (GPUSensors), it seems that it runs on high speed permanently. I saw that the 8600M GT and the 9500M GS are similar - only the GPU memory clock of 9500M GS is 10% faster than the 8600M GT. For example it doesn't need a FileNVRAM file to get iMessage working I already changed the AppleGraphicsPowerManagement so this worksĪctually I don't want to change back because I find Clover better. Maybe the graphic card has to calculate so much that this causes the problem Have you got an external monitor connected, too and check whether you also have also lags?
I write it in this thread again The lags from Mission Control, Application windows and switching desktops seems to be gone if I disconnect my external monitor. This seems to take care of it entirely if you have it plugged in at boot it disables the laptop screen on my machine at least that is why I say after boot plugin, no idea why the dummy plug does what it does but it works perfectly for this purpose. And if you ever use it not connected to the Dell monitor then notice some annoying flickering when it changes power states you will need a VGA dummy plug which you plug in after booting but before the desktop loads. You need to rebuild the caches or the change will not be seen and use MacBookPro6,1 as your device for this to work. I use MacBookPro6,1 for my ist on my 6920G which has the same video as yours the edited section looks like this. You can at least in Mavericks edit the AppleGraphicsPowerManagement.kext and put your device ID in one of the macbook entries. Also if you see "Error agpm controller unknown platform" then it means you are not getting proper power management for video card. The latest version of Chameleon will boot Yosemite so you are probably better off using that and getting the correct injection done. edit: I also attached my ist for Clover (with not injected Nvidia) and my dsdt, maybe you need this
Could I fix this by using EFI or something else? Has someone Mavericks / Yosemite, uses Clover and has a GeForce 9500M GS and tell me how to get it correctly work ( performance, battery safe on idle, QE/CI)? So what can I should I do? Inject graphic card or not? I prefer not, but my Yosemite should always start and not with luck.
But to can download iMovie, I used Clover for some minutes with the result that it recognised the wrong 8600M GT and the download did not start because of a low power GPU.Īlso it seems that not injected graphic card let Yosemite runs "smoother" (for example on scrolling through pages). In Mavericks I used Chameleon/Chimera which always recognised with GraphicsEnabler=Yes my GeForce 9500M GS correctly. I attached some pictures in System information with (not) injected graphic card and Chimera. It seems that this happen in the step when normally the cursor appears in startup (so before the login window). If Clover should not inject my graphic card, it tells me correctly that I have a GeForce 9500M GS but often on startup Yosemite, the notebook restarts again. But injecting graphic card makes booting Yosemite constantly. If I check inject Nvidia graphic card in Clover Configuration, Clover tells me that I have a GeForce 8600M GT.
It seems that this is caused by two problems, one problem is that Clover does not recognise my graphic card correctly. But I have several problems that caused that my system is a bit laggy especially using Mission Control and Application Windows. I successfully installed Yosemite on my Acer Aspire 7720G with Nvidia GeForce 9500M GS graphic card.
