KushKrime Posted April 5, 2015 Share Posted April 5, 2015 Hi everyone. I'm hoping somebody will be able to help me with power management on my system, because after months of tinkering I still can't get speedstep working. My problem is that after following the Power management for Sandy/Ivy Bridge/Haswell CPUs guide on this site and then installing the SSDT I get a black screen upon boot. I've tried booting in verbose which doesn't help much because it appears the system boots just fine right before said black screen. Anybody got any idea what my problem could be? I'll attach relevant files just incase. SSDT.aml.zip config.plist.zip Link to comment Share on other sites More sharing options...
KushKrime Posted April 6, 2015 Author Share Posted April 6, 2015 Bump. So can no one help me? I'm really trying to take advantage of my CPU but can't with only two states. Anything would help. Link to comment Share on other sites More sharing options...
Ezzyme Posted April 15, 2015 Share Posted April 15, 2015 I was getting the Black Screen of Death just after the boot loader. This article in OSXDaily saved me: http://osxdaily.com/2014/11/22/fix-macbook-pro-booting-black-screen/ Link to comment Share on other sites More sharing options...

Try boot with this boot argument: -v GraphicsEnabler=Yes IntelCapriFB=10 I was getting the Black Screen of Death just after the boot loader.

KushKrime Posted April 20, 2015 Author Share Posted April 20, 2015 Hello @KrushKrime. Before you go to States, you need enable your video first. Try boot with this boot argument: -v GraphicsEnabler=Yes IntelCapriFB=10 Thanks for the reply Allan, I had begun to lose hope in a solution. I tried the boot arguments you supplied and the result is the same, a black screen. Does "IntelCapri=10" apply to me when I'm using discrete graphics (R9 280X)? In addition I found that using "-xcpm" allows me to boot into my desktop but it also causes random restarts and really high multipliers even though I'm not overclocked; I used iStatMenu to see that.

Sorry i forgot about you R9 280X, the IntelCapriFB=10 boot argument is for HD 4000. 1 Link to comment Share on other sites More sharing options...

Allan Posted April 20, 2015 Share Posted April 20, 2015 Appreciate the reply. I've uploaded IOReg down below. Hmmm, man, your Power Management is very wrong: Put the SSDT in EFI/CLOVER/ACPI/patched And use this config.plist: config.plist.zip Is the config.plist above don't work, try this: config.plist 2.zip 1 Link to comment Share on other sites More sharing options...

I didn't have to use any other argument, but I am only seeing a turbo of 3.7ghz instead of 3.9. Maybe i should stay with iMac SMBIOS? Link to comment Share on other sites More sharing options...
Allan Posted April 20, 2015 Share Posted April 20, 2015 Ok. Now send me again other IOReg. What you use for your enable USB3? 1 Link to comment Share on other sites More sharing options...
KushKrime Posted April 20, 2015 Author Share Posted April 20, 2015 Uploaded. USB3 works out of box for me. I have not had to install or modify anything for it to work. Many thanks. IORegiMac.zip Link to comment Share on other sites More sharing options...
Allan Posted April 20, 2015 Share Posted April 20, 2015 Ok, now your Power Management is right! Make a test about your States following this guide: How to check your states – Using AICPMInfo, MSRDumper or AppleIntelInfo 1 Link to comment Share on other sites More sharing options...
KushKrime Posted April 21, 2015 Author Share Posted April 21, 2015 MSRDumper is reporting all states active, including 39x. I just don't know why my CPU only goes up to 3.7ghz turbo (37x) - based on Intel Power Gadget, and iStatMenus. Maybe that's as good as it will get haha. Anyways I think i'm ok with that so thank you much for helping me through this, it is very appreciated. This community is awesome! 1 Link to comment Share on other sites More sharing options...
Allan Posted April 21, 2015 Share Posted April 21, 2015 I recommend you use HWMonitor. Make a backup of your current FakeSMC, and use this plugins: 1 Link to comment Share on other sites More sharing options...
