Power management for Sandy/Ivy Bridge/Haswell CPUs

hydra1ysk · February 23, 2014

Hello

I don't saw any problem... it said:
Number of P-States: 15 (800-2200 MHz)
Adjusting C-States for detected (mobile) processor
Injected C-States for CPU0 (C1,C3,C6,C7)
So... P-States was found and they're in SSDT, but like i said, it doens't enable... you need find a SMbios that work to you... try diferents models

Try iMac 12,1/12,2

Thanks for your help.

I try all smbios, someones give me kernel panic and other i only get the same (only pstate 8).

i think maybe the problem is the AppleIntelCPUPowermanagement. I got a kernel panic, after i replace the file with the original file (OSX disk) and now i can boot without problems. what do you think about this?

edit: i found something.... when i replace the file i don't get problems, but if i repair cache, i got the kernel panic maybe this file it's the problem)....

hydra1ysk · February 23, 2014

I FIX IT!!!!

The problem always was the SSDT file of this script. I don't know why in my laptop never works.... I use google and i found the SSDT for all intel processors included the SSDT for my CPU (i3 2330M). The steps i follow for get the SSDT works:

1.- replace de SSDT file with the SSDT for my CPU. I attach the file for all SSDT for i3, i5 and i7 processor in this post.

2.- Patch AppleIntelCPUPowermanagement (for this guide)

3.- repair cache and system with kextwizard.

reboot and now my computer feels faster. i run a geek bench and i get this score:

NOW

http://browser.primatelabs.com/geekbench2/2426915

but now i have a question. I need information about the p-states in my laptop. where i can get this info???

Hello

Good New!!!

To see your P-States.. use this app: http://sourceforge.net/projects/dpcimanager/

DPCIManager p-states not working after update to 10.9.2, fine before.

Pimentel · February 28, 2014

Hello

Yes... i noted this when update...

Use this kext to know about P-States: https://dl.dropboxusercontent.com/u/126585663/AppleIntelCPUPowerManagementInfo.kext.zip

i see this in my haswell i5 is this good ?

Well,

it is something.In my case, most of the time I am in state 34 (i5 4570). Although I would love to save more energy.

try to use AppleIntelCPUPowerManagementInfo.kext. read about this here

Download the kext, open Terminal:

cd /Users/youuser/Downloads

chmod -R go=u-w /Users/youuser/Downloads/AppleIntelCPUPowerManagementInfo.kext

chown -R root:wheel /Users/youuser/Downloads/AppleIntelCPUPowerManagementInfo.kext

sudo kextload AppleIntelCPUPowerManagementInfo.kext

cat /var/log/system.log | grep "AICPUPMI:"

after this code, you will see results, like this:

if you see all states and turbo, everything works fine.

for unload kext, use the last code:

sudo kextunload AppleIntelCPUPowerManagementInfo.kext

Note: where I put "youuser", enter your User name.

relikwie · March 13, 2014

That version of AppleIntelCPUPowerManagementInfo.kext you linked to, crashes my hack as soon as I load it. It is mentioned by Piker.

He suggests to compile the a fixed version from source. Tried that but the resulting kext fails to load. It is my first compile in xcode, so probably

I am doing things wrong.

ham4ever · March 13, 2014

Thanks that worked good

i saw

Don't install in S/L/E, mentioned cd/Users/youuser/Downloads because it is easier.

relikwie · March 14, 2014

Don't install in S/L/E, mentioned cd/Users/youuser/Downloads because it is easier.

Hi All@n, it is being loaded from Downloads (placing a dodgy kext in SLE is asking for problems).

Piker says that the kext KP's or craches the system for some mainboards, guess mine is one of them.

It is also not his intention to provide compiled kext's as he reasons it is not meant for the general audience and nitwits like me.

Actually, I am wondering why we should have states ranging from 8 till turbo. 8 makes the system unworkably slow.

I currently have 16, 21, 28 and 34 (achieved by using the specs for my cpu using ssdtPRgen.sh) w/ smbios Macmini6,2.

If we would want it vanilla and how Apple does it for the iMac's, we should only have min and max (16 and 34Ghz).

cheers, relikwie.

ham4ever · March 14, 2014

i installed kext in S/L/E and i didn't get any KP lucky me i guess

What is your CPU?

i installed kext in S/L/E and i didn't get any KP lucky me i guess

Nice, the bad news is that lots of messages appears in the Console.

relikwie · March 14, 2014

What is your CPU?

i3-3245 CPU @ 3.40GHz

Allan · March 15, 2014

i guess it's normal, 16, 21, 28 and 34.

but put your signature, is best to help you. post about your LGA.

PiccioShow · March 21, 2014

Hello, I followed your guide for the hardware on my sign, All seems to be fine, but with ssdt and patched AICPUPM my hackintosh seems to be running a lot slower, how can I know what's wrong there?

Also the wake from sleep state is very slow, it requires around one minute, I don't know if it's regular...

thank you very much!

Attached is the ssdt that I'm currently using

EDIT: I downloaded DPCIManager (using ML 10.8.4) and I can see, if I boot with NullCPUPM, 16 P-states while I'm stuck at 16th.

If I boot with patched AICPUPM I only get 8, I'm stuck on 8th state and the console of DPCIManager gives me error messages like "P states: I/O error, trottling to 9hz" down to 1hz, and then "P-states: method failed, exiting 0xE00002CA"

What's going on there?

SSDT.zip

Allan · March 21, 2014

for me DPCIManager i have the same problem about P and C states.

try this method: AICPM Info

if you use Chameleon, erase Generate P and C states, which is on boot.plist.

never use NullCPU and AICPM together

PiccioShow · March 21, 2014

I built the system cache without NullCPU and then I put nullCPU in S/L/E so that I can boot with NullCPU using -f flag, or without it just booting from kernel cache...or at least I was thinking this could work...

I don't actually have Generate P stats and Generate C states in my boot.plist.

I'll try erasing at all nullCPUPM and looking around with AICPUPM info, thank you very much.

Allan · March 21, 2014

the kext AICPUPM info, it caters to inform you if the states are working.

will not replace AICPM

guan · March 22, 2014

Hi All@n,

I have followed this guide but I still can't check if states are OK. Unable to use AICPM, KP on launch this Kext.

And HWMonitor give only 2 coefficients CPU X8 and X 36.

More details here :

http://www.insanelymac.com/forum/topic/275429-hwsensors/page-50?do=findComment&comment=2005728

Thanks for your help.

PiccioShow · March 24, 2014

Nothing to do with AICPUPMInfo.kext, I can't enable it. WIth HWMonitor I can see my cpu freq stuck at 800Mhz.

Entering sleep mode and waking up HWMonitor shows 3,5Ghz.

also waking from sleep audio is not working anymore, showing in the conosolle IOAudioStream[xxxxxxxxxxxxxxx]::ClipIfNecessary()-Error... I'm using an external Firewire Sound card, maybe there's some problem with firewire

Allan · March 24, 2014

like I told you, AICPUPMInfo.kext is just for information. will not help you about the states.

none of the methods that are on this topic helpful to you?

PiccioShow · March 24, 2014

Sorry for my bad english, I think we have misunderstood. I know AICPUPMinfo is only for information, I'm not using it to replace AICPUPM or anything else, just trying to load it from the root folder with the terminal commands you gave, but It doesn't work, it said that it's not installed correctly...

anyway no, nothing found on this topic was helpful, I tried changing smbios but nothing changed, maybe I must regenerate ssdt and repatch aicpupm after each smbios change?

I tryied duplicating the last p-state in the ssdt created with the script, because I've found that this could be a solution for i7 3770k PR, but it doesn't work neither.

Allan · March 24, 2014

try using SMBIOS iMac 13,1.

maybe I must regenerate ssdt and repatch aicpupm after each smbios change?

That sounds good.
