ML: Native Ivy Bridge CPU and GPU Power Management

[toleda]

im a little confused. i got p8z77-v lk and followed this thread http://www.tonymacx86.com/dsdt/84495-asus-p8z77-vlk-motherboard-dsdt-help-2.html, but the OS stops loading just before the GUI is supposed to load. .

If your profile is correct; i5-3550 is not HD4000. No OS X support for HD2500.

running as iMac13,2, no OC, no DSDT, with SSDT from post#1. msrdump reports 12 16 37 38 39, as explained at post#1. I'm glad it getting down to 12, which saves some energy at idle (5 Watt). X86PlatformPlugin and X86PlatformShim is loaded. Geekbench-Score now 12949 (with DDR3-1333)

You have confirmed my test results. Is there a question?

on this thread, one user has 3570K IB PM working and another has 3770K working. Two 3570K users (both AMI BIOS) on supplemental 10.8.2 have problems. I don't have any other suggestions at this time.

At last I have IB CPU & GPU Power Management working on my P8Z77-M Pro. X86Platform is enabled by ssdt as follows:

Downloaded the latest version 2.5 of ssdtPRGen.sh from https://github.com/Piker-Alpha/RevoB...s/ssdtPRGen.sh, and edited in Textedit as set out in SSDT Generation Script (IB PM) post #71 by Intamara. Then opened Terminal and generated the SSDT (now saved to the Desktop). Opened in DSDT Editor and made the IB Power Management ssdt edits (in Scope(\_PR.CPU0) by toleda in post #1 of this thread, then deleted the duplicate Method (_DSM, 4, NotSerialized) section. I didn't need to duplicate the bottom p-state as some have suggested.

P-states so far using MSRDumper are: 16 22 29 35 40 43 which I am more than happy with.

I am using the latest patched bios update 1805 and 10.8.2 supplemental update 3104. Macmini6,2 symbios.

My ssdt.aml is attached below.

Now I hope I can make this work when using Clover bootloader. - it is working, no problem. Great.

Max freq is wrong. Read_me_first/II A. Generate SSDT - MaciASL/5. Set Maximum Turbo Frequency (MHz) + 100. Use 3800.

No luck.
I had to install AppleACPIPlatform.kext rollback from 10.8.1 (MultiBeast option) during installation process: can this affect Ivy Bridge Power Management?
Meanwhile I tried with 10.8.2 update (not the supplemental 10.8.2, but this one) No success either.
I will try with various combination of custom ssdt parameters and options.
Any other idea?
New files attached

Wow, thanks! Your SSDT made my rig: 3570K @ 4.2 OC on P67 work like a charm

MSRDumper PStatesReached: 16 21 28 35 40 42

Hi all,

My numbers:

MSRDumper PStatesReached: 8 17 18 19 20 21 22 24 26
Processor: i5-3317U
SMBios: MacBook Air 5,1

Many thanks, before my geekbench was 4110, now i get 5800 Am very happy

Question: Can someone please tell me how to fix this?

@ toledo
i have a 3770 i7,

 

[toleda]

No luck.

The attached SSDT.aml is not from this thread. Still interested in an IOReg with the ssdt suggested in Post #90. 10.8.2/12C60 is the only version used for all testing.

 

[toleda]

Problem: my log

Attach your ssdt.aml and a copy of IOReg. [Guide] How to Make a Copy of IOReg.

im a little confused. i got p8z77-v lk and followed this thread http://www.tonymacx86.com/dsdt/84495-asus-p8z77-vlk-motherboard-dsdt-help-2.html, but the OS stops loading just before the GUI is supposed to load. i'm using imac 13,1 as the smbios.plist definition. the bios is 0908 and has been patched to support native power management. i actually got it working before to boot in non-safe mode but now it doesn't work.
i also put the gpu id thingie to 9 as someone else did on the forums, but no dice. the bootloader is the stock one that comes with the latest multibeast.

Off topic. Post in Installation forum.
