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:


Any help would be appreciated

According to that output, you have lots of p-states, so I think you were successful.
In my Broadwell-E system, I only have one p-state still. How are you booting? Any fakecpuid?

I don't think the output from AppleIntelInfo.kext is sufficient. It doesn't show how much time is spent in each state. See my posts #103 and #105. How does the differences between my 2 outputs explain the difference in performance? I don't think it does unless I'm missing something.

I haven't been able to make my SSDT at all, so the output is whats already running

Also the Max turbo Frequency is 3.8Ghz on this chip, so it's definitely not right

this is what i'm running

Hi all, Piker Alpha told me to
Are you using this update of AppleIntelInfo.kext? That one works perfectly fine here.

And all that you really need is: ./ssdtPRGen.sh -turbo 4000

Either that or any other higher turbo value that you use in the BIOS for when you OC your setup.

What's that about: "But still the same error"? What error are you referring to?
Click to expand...

So my new AppleIntelInfo.kext output now looks like this:
So it looks like i've "lost" some CPU P-States and they've all changed:

CPU P-States [ (12) 33 35 ]
CPU P-States [ (12) 30 33 35 ]
CPU P-States [ 12 30 31 33 (35) ]
CPU P-States [ 12 30 31 33 34 (35) ]
CPU P-States [ (12) 30 31 32 33 34 35 ]
CPU P-States [ (12) 28 30 31 32 33 34 35 ]

and these have changed from my original output without inserted SSDT

IA32_MPERF.................(0xE7) : 0xB5578D459
IA32_APERF.................(0xE8) : 0xB2115D8A2
IA32_THERM_STATUS..........(0x19C) : 0x88520000
MSR_PKG_ENERGY_STATUS......(0x611) : 0x53D3328
IA32_TSC_DEADLINE..........(0x6E0) : 0xA3C0D07269

Edit edit (3rd time)

Piker on his blog explains why:

Intel® Turbo Boost Max Technology 3.0 is only used for Windows software and not OSX

Is it full speedstep? also i wonderwhy can't check speedstep with method using Console app with AppleIntelCPUPowerManagementInfo.kext?

Forgot, i'm using Sierra. Maybe cause is AppleIntelCPUPowerManagementInfo.kext not support Sierra yet,right??

hi all
i created ssdt using this guide and it went well but I am unsure if its working fine and is there any clover changes need to done I have P states and C states enabled and here is the output with a warning Warning: 'cpu-type' may be set improperly (0x0705 instead of 0x0905)

Ya, also waiting for Broadwell-E. 1 C and 3 P-states atm... (6850K)
Also the ssdtPRGen -show flag does not show squat for some reason (-s gives error)...
