This guide is for get a working Power Management on any X79

 

1. We need to patch the AICPM with the OMNI patch otherwise it will never work. I made a command file for this, Open with double click a type your password. (Is only if you have a Sandy Bridge-E if you have a Ivy Bridge-E skip this step)

 

Perl patch: 

 

10.12 aicpm patch.command.zip

 

Or

Clover patch (If you prefered to use the clover patch not need to use the perl patch)

Using clover configurator is easier. Your clover configurator have to see like this.

2. We need to patch the Msr lock. For this we need download the following script. (Is only if you have a board with msr lock if you have a Asus or Asrock skip this step)

 

AICPMPatch

 

NOTE: Clover has the MSR lock patcher but for some reason does not work with X79 platform.

 

 

3. Finally we need to download the following dummy kext and put it in /System/Library/Extensions/

 

10.11 X79PlatformPlugin.kext.zip

 

 

4. Now is time to create it a SSDT for our cpu for this you need download the ssdtPRGen.

 

install.command.zip

 

5. Download InsanelyRepairPermission and repair and touch with

sudo InsanelyRepairPermission -rt /

Greetings stinga11 from Sydney Australia.

 

I am interested in building an X79 HackT based on the E5 1660 v1 (Sandy Bridge EP). It would, ultimately, serve as an "Octane" rig (potential for multiple nVidia/CUDA cards).

 

Its like a slightly better binned version of your 3960X + pcie3 + lots of ram, as you can see:

 

http://ark.intel.com/compare/63696,64620,70845,77780,75780,75781,77912

 

Do you know of anyone that has made a successful Sandy Bridge EP, E5 1660 v1. I've only seen omni get so far before abandoning the idea, and you (with a few others, mainly shilloh) seem to have stuck it out with Sandy Bridge.

 

I note Pike has made some recent strides in XCPM on non supported hardware, and thought you might be able to extrapolate to this use case?

 

The price of (allegedly ex server oem) overclockable E5 1660 v1's is very attractive.

 

Anyway, thanks for considering this request.

All the best.

Hmm... on a dual Xeon 2650 Sandy I'm getting KPs, but I'm seeing a lot of ACPI problems during boot with FakeSMC plugins, so I removed for now the SSDT-1, will re-patch AICPM and will try to generate a new SSDT-1 and report back.

 

EDIT 1 : Did a new SSDT but PM isn't working or at least performance isn't what it should be. So testing again with SSDT which was working under El Capitan.

Works great now thanks for the patch man :)

 

btw how do i test if i can use xcpm with my sabertooth x79 and 3930k cpu and ?

 

I enabled the kernel flag -xcpm in clover and even KernelPM flag then booted back to the system and then tried to see if it work with terminal command sysctl -n machdep.xcpm.mode but it returned 0 :( what did i miss i hope you could help me.. should i generate new SSDT.aml ? even used mac pro 6.1 and that didn't help. the cpu don't clock down and stay on 3.2ghz and imagen how the south bridge fan sounds :P not to mention how hot the cpu get after 5 min

The XCPM doesnt work with sandy bridge, Sandy bridge E and Ivy bridge E. Piker Alpha found a couple of new pacthes that can enable the xcpm on the future.

Thanks for following up with Pike, and translating for us 'mortals'.

 

FYI. I am trying to learn (hello command line, where have you been my whole life!)... maybe this can shed some light on some of the minor architectural differences in i7 vs E5 1660:

Ok, did more testing on the dual Xeon Sandy here, and Clover "on the fly patching" doesn't work... I patched AICPM manually and replaced the file but still got KP's (for what reason I still don't know).

 

Good news is that I did a rollback to my El Cap patched AICPM and it works, PM is working under Sierra!

 

Third public beta is out, so I will update the system and try again, and of course report back if this is working or not on this particular rig ^_^

Don't use the El capitan patches with Sierra, only two patches are still the same the others five patches changed.

Thanks to you stinga, now I have a working x79 machine in good condition with Sierra. I have x79-UD3, E5-2670 and GTX670 config.

 

With 10.12 official retail, Speedstep & sleep were working well (use SSDT generated by ssdtPRGen.sh (Piker Alpha's))

Now I am in 10.12.1 Beta 5, and do not have any problem with power management. At least it seems.

Thank you Stinga. Your patch info have helped me a lot since El capitan.

As always thanks to Stinga for the excellent work on this.

 

For those who are interested you can still patch the MSR (if you need to) from Clover. The same patch I used in El Cap works for Sierra.

 

At least this works on my X79-UD5. It saves having to run Omni's patch with every update.

Just an update to myself, when I said the patch doesnt work on 10.12 (AICPM 290) and causes kernel panics - it was related to a locked MSR on my board - implementing the Clover flag for the MSR unlock makes the kernel panic go away and power management works great.

 

So some boards like mine KP on the latest AICPM but didnt before.

I'm having trouble getting this working on an ASUS P9x79PRO & i7-3960X (it is overclocked to bclk 125, freq 4135, turbo 4500). I have it set as MacPro5,1 

 

I followed the steps above and patched the AICPM using clover configurator. I skipped the MSR as I have an Asus motherboard. How do I check it is not locked ? (I run an over clock in Windows with no issues)

 

I Dowloaded and installed the X79PlatformPlugin.kext. Although this doesn't load automatically. I put it in SLE and also on clover kexts. If I look in System Information I see not loaded and Signature Validation Errors: Kext signature validation error code -67030. I have SIP Disabled and can load the kext manually once the system is loaded.

 

I created the SSDT - it did give me a warning and I am using MacPro5,1 and a Board-id autogenerated by clover I think.

Thanks stinga, I have changed to MacPro6,1 - however it is still not working.

Do I need to worry about the warnings & use any other parameters for the ssdtPRGen.sh ?

 

Any help appreciated, thanks

You can not be use a MacPro5,1 definition because this guide was made to use a MacPro6,1 definition.

 

I've been using MP5,1 just fine on my X79 with your patches and a SSDT. I don't use the kext as it's designed for MP6,1. Speedstep is working as is Turbo.

 

ccozmo: type bdmesg into Terminal and have a look for MSR. Clover should patch it automatically if it detects that it's locked. It looks like we have the same board and mine doesn't have a locked MSR. Then check that all 7 patches to AppleIntelCPUPowerManagement are being applied.

 

I'm not overclocking my 3930k so I didn't use any custom parameters with ssdtPRGen. Just let it build a default SSDT for the CPU.

 

If you're still not getting any working speedstep, have a look at your CPU settings in the BIOS and see if anything there might be the cause.

Did you do anything special with your SSDT ? What parameters did you use ? Are you running Sierra ?

 

Can I see your SSDT and config.plist for Pro Mac ? Seems very close to my build

Here they are. I just edited out the serial numbers from the config.plist.

 

You're probably better using MP6,1 if you can as it's a closer match to the hardware. I originally built this machine to run Snow Leopard, so that's why I've stuck with 5,1.

Thanks Riley
