Not all P-States are used

[acidos77]

Just installed El Capitan on the following hardware:

 

i7-2600K

GA-Z68X-UD3H-B3

MSI Radeon HD 6870

Latest Clover loader

 

Before I had(still have) Yosemite on the same hardware working perfectly, including P-States. It was giving me most of states

 

AICPUPMI: CPU C6-Cores [ 0 1 2 4 5 6 7 ]

AICPUPMI: CPU P-States [ 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 (38) ] iGPU P-States [ (17) ]

 

 

It was configured using ssdtPRGen.sh, produced SSDT, copied into EFI partition.

 

Now after I installed El Capitan, I copied the same SSDT and the same clover configuration. However, the results are not like for Yosemite. This is the most I could get.

 

AICPUPMI: CPU P-States [ 16 35 36 37 38 ]

So I assume that my CPU is just running on close to max power, which is not effective. Also I don't have any iGPU states.

 

Worth to mention, that I am only using FakeSMC kext, located on EFI's kext folder. For states, I put AppleIntelCPUPowerManagementInfo.kext into the same kext folder.

 

Any help to find solution is appreciated.

Try this: config.plist.zip

 

And run Piker's scrips again, look what i found in your SSDT:

Store ("ssdtPRGen version: 9.1 / Mac OS X 10.10.3 (14D136)", Debug)

That could be it, but I can't run the script on El Capitan. This is how I was running on Yosemite, but on Capitan I get this warning:

The following also not giving me the list:

Error: 'TDP' must be in the range of 10-150 Watts... exiting

So I am little stuck on generating new SSDT...

Hmmm, about this, is good you talk with Pike.

 

Maybe it bug in his script..

Meanwhile I am unable to use USB3. If I enable USB3 from BIOS, Capitan will stuck on 

 

PCI configuration begin

 

On Yosemite I was using XhciDxe-64.efi and clover-patching AppleUSBXHCI. For Capitan this patch is not available and I am not even sure whether the freezing is before AppleUSBXHCI or after.

For the p-states you get what Apple uses for the machine you have defined as your model if you want proper lower power usage then use windows or linux anything but OSX basically, usb3 support is borked in El Crapo there are numerous threads all over the internet on this epic fail by Apple.

If you're interested in having lots of P-States then iMac is not the best choice, try a MacBookPro8,x model.
