ML: Native Ivy Bridge CPU and GPU Power Management

[demonknight9]

Hi again guys, toleda, just one quick question, I have changed motherboards and instead of the h61m-d2h-usb3 I now have a series 7 z77-ds3h after reading again the first post I am unsure wether I should use the ivy power management like I was using with my last series 6 board./QUOTE]
Yes, PM is for the processor not the motherboard.

Many thanks

So CPU PM seems to be working for me with my i5-3250K, right? I'm using the Macmini6,2 sysdef.

6/26/13 11:09:48.000 PM kernel[0]: MSRDumper PStatesReached: 16 22 28 34 39 41

Edit: I read through a bunch of the earlier posts in the thread, and I now know how to verify the following. I'll check this evening when I get home from work.

How can I verify that the GPU PM is working though? I have a GTX 670, and GPU frequencies etc are not showing up in my HWMonitor (just installed the latest FakeSMC plugins from MultiBeast to be sure, but still nothing there.) I'm using a DSDT for my P8Z77-M Pro with PJALM's MaciASL patches, and mrengle's AppleNativeGPUPowerManagement.kext.
Sorry if these are stupid questions – I've tried reading up as much as I could, but I'm a bit lost, so any pointers would be very appreciated.

Hey toleda, just clarifying. You replied to me earlier and said to use Sandy Bridge sysdefs & Sandy Bridge PM with my Ivy Bridge CPU & mobo? Is that right? I don't understand. I am using the Mac mini 6,2 sysdef and I can see my multiplier going from 16 to 46. Not sure if that means it's already working or not.

A general question too, if you will. Is the idea to get on the same platform regardless of CPU? Like since I have a 3770K, is getting on a sysdef of an i7 mobile board like the Mac Mini what I want? Or is the idea to get on a similar sysdef to your CPU, regardless of platform? Like since the 3770K is similar to the 2600K, do I want to get on a sysdef with that CPU? Thanks in advance for your radiant wisdom

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?

Post to SSDT generation script (Ivybridge PM) . Include log when the script ran.

I have tried MSRDumper.kext and it reads only one pstate. pstatesreached = 35 now I have patched my bios and it reads two pstatesreached = 16 35. What does it mean? I have attached screen shots of the console reading the pstates and appleintelcpupowermanagement timing out. This is really confusing.

This is really confusing.

ML native CPU power management is disabled with S/L/E/NullCPUPowerManagement.kext installed. Remove the kext, repair permissions and cache and restart. Reply with IOReg.

I searched /s/l/e but there is no nullcpupowermanagement installed.

So… I'm getting some weirdness here. I'm in the midst of switching bootloaders from Chameleon to Clover, and I think I've gotten Clover to load my SSDT (I dropped it in /EFI/CLOVER/ACPI/patched as SSDT.aml, and have set DropOemSSDT to Yes in config.plist.)

I'm getting the following errors during boot:

6/28/13 11:23:07.000 PM kernel[0]: X86PlatformPlugin::setRingTable - AICPM failed to load ring table with status 0x0: Get=0, Load=0, Install=06/28/13 11:23:07.000 PM kernel[0]: X86PlatformPlugin::configResourceHandler - Failed to set ring table!

The weird thing is though, that speedstepping seems to be working:

6/28/13 11:28:43.000 PM kernel[0]: MSRDumper PStatesReached: 16 26 34 39 41

And in IORegistryExplorer under X86PlatformPlugin I have 36 CPUPStates values and 5 CPUCStates ones..

So, am I good? Can I ignore the errors or do I need to do anything to be safe? I'm using MacBookPro9,2 sysdef (getting less P-states than Macmini6,2, but Geekbench score is almost 1000 points more). Attaching ioreg if it matters.

Your Console log shows NullCPUPowerManagement.kext installed and interfering; keep looking. Otherwise, clean install.
