I have a 5820K (Haswell-E) with Asus x99 Pro USB 3.1 and the next situation with the Power Management:

1st scenario:

-NullCPUPowerManagement.kext (has no effect) & SSDT with XCMP active (I also applied frecuencyVectors.sh to my MacPro 6,1 SMBIOS). I'm not sure if I applied clover Kernel PM patch at one point of my current system and it is the reason why XCPM works.

-Side effect: The BIOS values about C states, IntelSpeedStep or Turbo Frecuencies Intel features has no effects on SO (XNU CPM). It always are enabled despite the BIOS values. Another thing I noticed was low CPU performance on Apple Logic Pro than the before times when I used the 2nd scenario.

2nd scenario:

-Using NullCPUPowerManagement.kext and FakeCPUID to 0x0306E0 (Ivy Bridge E5) which has no XCPM. I also restore the original frecuency vectors plist (on X86PlatformPlugin.kext) which came with the OS installation.

side effect: With this fake CPUID, I cannot run the system without NullCPUPowerManagement.kext. Also I tried to set clover patch Asus AICPUPM to use the native AppleIntelCPUPowerManagement without NullCPUPowerManagement, but only boots with NullCPUPM...

It does not matter, because the fact is that I have more performance at 2nd scenario with software that I normally use.

I also have C-States and IntelSpeedStep in the 2nd scenario. The difference with 1st scenario is that the CPU doesn't reach the nominal frecuency. I mean the Turbo Boost does not work on 2nd scenario (I figure it is about the fakeCPUID P-States watching the AppleIntelInfo.kext output. Only shows 33 on top of P-States list on this scenario. The SpeedStep works because I can get for example 1,2 Ghz, and on the P-States List I can see the value 12). Another difference is that I can disable this Intel features by BIOS and the OS understands the change. (On this 2nd scenario I'm sure that XCPM mode is 0 by 'sysctl machdep.xcpm' command output)

Observation:

I think it is not an effect of SpeedStep because I try disabling/enabling on 2nd scenario, and the SO recognizes BIOS values and all works apparently equally fluent. My suspicious of my performance fall with XCMP (1st scenario) is that XCPM does not manage my cores as well as without it. All the features works but not at the same performance that without it. I notice it with the CPU performance meter and the behaviour of the software, with the same project on Logic. At first scenario the CPU is burnt (not all cores are working) and I have audio system overflow and Logic stops. At second scenario I have a lot of CPU free (with a balanced use of cores) and the program flows without overflow.

After that, my question is: Can I disable the XCMP without making a fakeCPUID 0x0306E0?. It is the only way the system disables XCPM. At 1st scenario I have NullCPUPowerManagement installed on S/L/E but it does not matter because it has no effect while I don't fakeCPUID. I test removing the CPUPM SSDT but the XCPM mode is still active.

The behaviour of 1st scenario could be a previous execution of my system with clover flag Kernel PM patch active, and my kernel is already patched forever till I replace kernel file with the original. I read that the Kernel PM patch permits the XCPM on the CPU implemented at kernel level and it does not matter if I have NullCPU kext or AppleIntelCPUManagement.kext. This last conclusion fits perfect with my 1st scenario casuistry.

I think that the problem with XCPM could be a C state switching problem. I think my monocore performance on Geekbench in my 1st scenario is minly higher than on 2nd scenario as opposite than the multicore. My suspicious is that XCPM not hang well my high cpu processing situations.

Thanks all people and I hope my situation helps others. For now I am using 2nd Scenario about the performance fall with XCPM.

For my custom CPU SSDT that is always, on 1st and on 2nd scenarios, located on clover ACPI/patched folder. I also add -x 0 on ssdtPRgen.sh but no effect. With my real CPUID, the XCPM is always active.

XCPM Performance fall solution (Asus x99 Pro USB3.1 + i7 5820K, Haswell-E):

I've applied the next steps to fix the performance problem I described (low perf. on XCPM vs high perf. on NullCPUPowerManagement.kext + FakeCPUID)

Works on both (Sierra and El Capitan):

0.-No clover kernelPM, Asus AICPUPM, Haswell-E, or similar predefined Clover's patches. No FakeCPUID and delete NullCPUPowerManagement and AppleIntelCPUPowerManagement and AppleIntelCPUPowerManagementClient kexts.

1.- frecuencyVectors.sh for MacPro 6,1 on Haswell-E, patched by the script suggested on ssdtPRgen.sh output.

2.- on ACPI clover section, SmartUPS to YES and reboot. After that I don't have the warning 'system-type 1 instead of 3' on ssdtPRgen.sh. I generated my SSDT then I copied to EFI/Clover/ACPI/Patched location. No DropOEM checked but I have these entries on Clover's DropTables array from ACPI section:

3.-Apply the next patches on clover KernelToPatch section.

Now I can play my logic project and no problems. Like at the begining with NullCPU but with a lower CPU temp and power consumption than before and now with turbo frecuencies...

You can see that cpuid_set_info patches are disabled because Picker Alpha says on his blog that this values are included now on Kernel by Apple.


Thanks to Piker-Alpha

Working like a charm now, my 6700K is throttling down to 800Mhz and Turboing to 4.4Ghz just like it should.

Done.

Download the script manually from his Github page, replace the version you've already got with the version you manually downloaded then follow the guide again (obviously skipping the part where you download the script). Worked for me :)

Rank SSDT newb here (sorry). I just upgraded to Sierra, and the generated OC SSDT appears to be limited to 4200. I'm OC'd to 4600. So, I tried the Pike-Alpha ssdtPRGen.sh to generate a new SSDT, and used the -f 4600 option. Dropped the resulting file into the proper location, but on reboot got 3900, by system non-OC default as the top speed.

Here's the output, where I notice a motherboard error and a system 1,2 error, but compilation is error-free:

AML Output: /Users/tracyv/Library/ssdtPRGen/ssdt.aml - 2256 bytes, 28 named objects, 45 executable opcodes

Compilation complete. 0 Errors, 0 Warnings, 0 Remarks, 0 Optimizations
Mine is a old, reliable system, so: is it the errors that are keeping me from getting 4.6? The 4.2 SSDT is working of course, but it would be nice to get back my 4.6.

I'm new to using ssdtPRGen.sh, so I'm not sure what to do to fix the issue, or even what it might be. Comments and suggestions greatly welcomed.

I don't really know what the first instruction means: "Configure system with appropriate SMBIOS for your CPU using Clover Configurator"

I have the latest clover configurator but I don't know what would be an appropriate SMBIOS and what would not be.

I went ahead with the Sierra install recommended smbios sys def of 14,2, however I'm using an old Sandy Bridge i5. 14,2 iMacs are Haswell. Is that why I'm having trouble? I followed the process to copy the ssdt.aml, however I couldn't follow the process to check functionality because terminal says

bash-3.2# sudo -s

bash-3.2# chown -R 0:0 ~/Desktop/AppleIntelInfo.kext

bash-3.2# chmod -R 755 ~/Desktop/AppleIntelInfo.kext

bash-3.2# kextload ~/Desktop/AppleIntelInfo.kext

/Volumes/Data/TOA/Desktop/AppleIntelInfo.kext failed to load - (libkern/kext) authentication failure (file ownership/permissions); check the system/kernel logs for errors or try kextutil(8).

bash-3.2# kextload ~/Desktop/AppleIntelInfo.kext

Recommended for your system is iMac 13,2.

I tried 13,2 and got the same result in terminal. Do I just keep trying lower and lower system definitions until I get a different response from that terminal command? How low can I go with iMac or Mac Pro in order to keep Sierra?
