Hi thunder72fr,

You've managed to apply DSDT patches through Clover binary patches.

Can you please let me know where did you fin these ? Is there any guide ?

I'm trying to not generate an DSDT.aml and instead make all patches go through Clover on the fly generation...

Thanks for your help in advance.

Boa sorte,
Paulo

After following the tutorial i do seem to have more p states however my average frequency seems to be much higher at idle according to Intel Power Gadget.
Is this normal?
Before it only seemed to stay high if i was opening heavy app or doing something that would justify it, in this test i opened adobe premiere before putting the file in clover.

Help?

Visit http://ark.intel.com to gather the required data:

Processor Number

Done.

I have the same error.

Hey, can someone help me on with this AppleIntelInfo.kext. As soon as I load it, the pc reboots. I did pull the SSDT.aml from the script and copied it to the patched directory inside Clover.

I have a i7-5820K, if someone has a good SSDT for it, I will take that too unless my SSDT? confused here.

thank you

I'm running a 2700k i7 CPU and, at first, my install of El Capitan would have a panic in AppleIntelCPUPowerManagement.kext so I put the NullCPUPowerManagement.kext in the EFI partition of my boot drive (a standard 64GB USB drive) and that seemed to solve that issue.

Now I get a hang when the loading bar is full and in verbose mode it says this:

hfs: set VeryLowDisk: Vol:Untitled, freeblks:0, dangerlimit: 12

Is this a problem with the SSDT?! How do I fix it?

For those with Skylake systems, ammulder has extracted SSDTs for power management for most CPUs in the following thread (not setup for overclocking):

Simply download the SSDT for your CPU and place in Clover's /ACPI/Patched folder. Be sure your system definition matches your CPU.

Any suggestions on getting this to work with Broadwell-E? I have a 6950x and it only shows one P-State. I ran Pike's script and installed the SSDT, but it did not help. I'm using fakecpuid=0x0306F2 to make this system boot. Intel Power Gadget shows my CPU flatlined at 4GHz all the time.

Code:

16:555  0:022  Inserting ssdt.aml from EFI\CLOVER\ACPI\patched ... Success
16:583  0:028  End: Processing Patched AML(s)
16:595  0:011  Out of control with CPU numbers
16:606  0:011   CPUBase=0 and ApicCPUBase=0 ApicCPUNum=20

Compile and use the latest version from GitHub. If there's still a problem, follow the troubleshooting method described here: https://github.com/Piker-Alpha/AppleIntelInfo/issues/8#issuecomment-188892586

Hi all,

I'm trying to use TonyMacx86 above guide and I keep getting the:

Error: Unknown processor model

I'm using the:

Version 15.8 - Beta

Which is supposed to have broadwell E support from what I can tell in the config files:

# With Intel Turbo Boost Max Technology 3.0
#
#i7-6950X,140,800,3000,4000,10,20
#i7-6900K,140,800,3200,4000,8,16
#i7-6850K,140,800,3600,4000,6,12
#i7-6800K,140,800,3400,3800,6,12 (that's the one i'm using)

I tried running with the flags:

-p 'i7-6800K' -f 3400 -turbo 3600

But keep on coming up with the same error

I've also downloaded the latest AppleIntelInfo.kext and get the following information if it helps:
