SSDT generation script (Ivybridge PM)

[zetje01]

If you're using Chimera or Chameleon bootloader, in /Extra you'll find ssdt_pr.aml. Just rename it as ssdt.aml, install AppleIntelCPUPowerManagementInfo.kext, reboot and check speed steps as stated in that thread from Pike

Thank you!
Found the ssdt_pr.aml, renamed it, rebooted, and the speedstep readouts are:

Jun 20 15:47:15 pauws-mac-pro kernel[0]: AICPUPMI: CPU P-States [ 33 ]
Jun 20 15:47:24 pauws-mac-pro kernel[0]: AICPUPMI: CPU P-States [ 16 33 ]
Jun 20 15:49:37 localhost kernel[0]: AICPUPMI: CPU P-States [ 16 33 ]
Jun 20 16:57:21 localhost kernel[0]: AICPUPMI: CPU P-States [ 16 33 ]
Jun 20 17:21:54 localhost kernel[0]: AICPUPMI: CPU P-States [ 16 33 ]
Jun 20 17:22:00 Pauws-Mac-Pro kernel[0]: AICPUPMI: CPU P-States [ 16 21 33 ]
Jun 20 17:23:29 pauws-mac-pro kernel[0]: AICPUPMI: CPU P-States [ 16 21 27 33 ]

So I think creating (and using) the ssdt file has worked!
That is cool. I suppose 4 frequencies are the native states. Fine by me.
One hour ago (while waiting on an answer about the not working ssdtPRGen-script) I already installed that AppleIntelCPUPowerManagementInfo.kext and then I only had 2 states: 16 and 33
Glad to know my CPU is now running at speeds it's suppossed to.
(by the way, in HWmonitor/graphs i can clearly see the 4 speeds)

Thanks for helping me!

I want to OC my 3770k to 4.5ghz when I try and make an ssdt for it with ./ssdtPRGen.sh i7-3770K 4600 it stops at 2.2ghz when i stress test. what gives?

Hi, I got a few warnings when running the script.

Anyone know how to fix it?

Can somebody explain me, step by step, the process of 'duplicating the lowest p state' to fix the 'stuck at 800mhz' problem i have on 10.7.5 with my 3770k???

on my mountain lion partition speedstep is working fine when using the generated ssdt.

thanks in advance

Does Lion even have Ivy support? I don't think so. You would need to use SandyBridge PM w/ Sandy style SSDT.

I have recently started using iMac13,2 as a model on my hack to fix an audio glitch I had but noticed there are only x16 and x39 available as multipliers which appears to be correct.

Using the script, is there a way to increase the number of steps but keep the system definition (I am working my way through the thread...slowly!)?

That is normal for iMac sysdefs. Try MacMini instead.

 

[D-an-W]

I was hoping to be able to do it using iMac sysdefs, can I get at least three (I seem to have two at the moment)?

I think that is the way Apple wanted it. I've read reports that it works the same on real iMac. If you ask for iMac, you get iMac...

Hello

I have Ivy Bridge Xeon, 3.4GHz and max turbo of 3.8GHz. Currently running with no DSDT or SSDT of any kind and MacPro3,1 sysdef. I have 16 17 18 19 20 33 34 36 and sleep does not work (machine wakes up immediately).

I think I should and could use this script. I assume it knows about my CPU. But am I required to have a DSDT too, and which one of the Ivy sysdefs should I use? I do not care about overclocking. And when and how should I change my platform type, if at all?
