What I did for USB3 is I bought one of these https://www.amazon.com/gp/product/B00JFR2H64

and disabled the on-board USB3 from the bios, and patched the Z820's USB3 cables to this card, so the front USB3 plugs would work.

 

 

 

wow, this is a great idea !

 

 

Now I tried use it on the z820 too and I got working USB3 without errors, freezes, etc (like with GenericUSBXHCI.kext).
Yes, I still not see USB3 controller in the System Profiler, but it is not a pain for me ;)
 

 

:huh: I'll try as soon as possible ... This would be absolutely great !!!!!

 

About SATA connectors, connect the SSD to grey (11) :

They are the native achi SATA controller.

 

-The 4 white next to them (15) , is the SCU controller. Forget it.

-The 6 white on bottom of the mb (13) is the LSI controller. From mac os they are only visible if you boot with the astek driver patched in this thread. Anyway I suggested you that use the grey connectors for the System HD.

bilbo, thank you.

 

I’m slightly confused…

 

About SATA connectors, connect the SSD to grey (11) :

 

 

They are already here… 

Hmmmmm… Maybe I should to change SATA-mode in BIOS from "AHCI+RAID" to "AHCI"? I will try to do it…

Am I right that it will not affect on SAS ports (there is RAID 1 with data HDDs)?
Sorry for stupid questions, but it is a new MoBo for me, and I not explored it completely yet.

Yes, it clear for me. As I wrote above, data storage is connected there; and seems like it works OK. At least no issues at the moment. But thank you in any case.

oh, yes, that is. The ACHI setting has to be set to "AHCI" only.

 

And no, that doesn't affect to SAS ports . It only affects to native ACHI , grey connectors.

 

By the way, I tried with mXHCD and it doesn't work. I have some patches applied, and maybe it needs take a look with more attention. To makes it shorter, could you send me your efi folder?

Done.
It is an EFI folder which I use now.

Seems I was inattentive again. My kext and kexts from X79 package have a slightly different size.

Let me know if I can help with something else.

 

UPD: Yes, my problem with "lost" SSDs is solved. Just switch from "AHCI+RAID" to "AHCI" in BIOS.

bilbo, thank you once again.

 

UPD2: Attachment deleted. Working kext you can find in post #159

Or direct link to download it

As you guess, the external icons patch has no effect on the Astek driver.

 

There is a way, but it cannot be done with Clover, so you have to directly modify the Astek driver:

  1. Find the AstekFusion2Adapter.kext
  2. Right click and "Show Package Contents"
  3. Open the "Contents" folder
  4. Edit the info.plist file. Look for:
<dict>
  <key>CFBundleIdentifier</key>
  <string>com.apple.iokit.IOSCSIArchitectureModelFamily</string>
  <key>IOBundleResourceFile</key>
  <string>SASHD.icns</string>
</dict>

and replace with:

<dict>
  <key>CFBundleIdentifier</key>
  <string>com.apple.iokit.IOSCSIArchitectureModelFamily</string>
  <key>IOBundleResourceFile</key>
  <string>Internal.icns</string>
</dict>
Save it and reboot.

 

 

 

If by "that environment" you mean using the Astek driver, the answer is no. Your card is a MegaRaid 12Gbit/s adapter and the driver is for 2nd generation, 6Gbit/s, FusionMPT ones.

Thanks. That's what I thought but hope springs eternal.

I can´t understand your config files.. ^_^  It's different in several aspects .. but what I don't understand is how your usb works ...without usbinjectall kext. I tried to copy your config without this kext and usb stops working ... how I expected.  Btw, you have a 5,1 smbios ...  ?¿?¿? Could you tell me what steps followed to fix usb?

Don’t try to understand, it is a test versions, not final for work.

Yes, I still have a 5.1 SMBIOS. I need to verify an one assumption (if it will be correct, I post it here).

 

Could you tell me what steps followed to fix usb?

 

Just remove GenericUSBXHCI.kext and add mXHCD.kext

Kext only you can get in attachment to this post.

 

but what I don't understand is how your usb works ...without usbinjectall kext

 

Are you sure?  ;) Look at screenshot…

No, I decided to start from El Capitan following to your manual.

And I have a bad apprehension now… kext can be not working under Sierra… I can’t test it now…

Hi guys,

 

A little optimization for our Z820 in multithreaded software use could be this:

 

Disable NUMA memory implementation in BIOS. It seems Mac Os X doesn't take aware of NUMA and then it's not optimum if enabled.

 

I get 51000  Geekbench 3 multithread (When NUMA disabled) in oposite to 49000  (when NUMA enabled)

 

This maybe lost a few points on single-thread.

 

Test your own to confirm if your CPUs benefit from this.

Glad to hear that it works not for me only :)

 

I think that I will delete an EFI folder from my post and leave here a working kext only.

In general, I followed the guide, especially instructions about DSDT/SSDT. I hope it is obvious from the picture that I did it on Sierra, not El Capitan. I don't use raid, only a single Samsung SSD for target install and HDD instead of USB stick.   



BIOS version = 2.15.1229
Clover version = 2.4k rev 4077


DSDT/SSDT/config.plist in the attached file


The system is very stable, everything works great (all software I use, for example: LightWave 3D, Cinema 4D, RealFlow, FinalCut Pro, LogicPro X ...). As far as I can see the only glitch is when the system resumes from sleep animations in GUI are a bit laggy - probably this goes to NVidia driver. It would be nice if someone tests my configurations (in the attached file) since I think there might be a room for improvements. What I miss the most, are working USB3 ports. As I can see, only two USB2 ports are working.  


Regarding ssdt.aml, first I created SSDT for my CPU E5-2670v1. Power management seemed to work and power consumption of the system was 140W (Wattmeter is always pluged-in), but Geekbench (Multicore Score around 22k) and my renders were too slow compared to Win7. HWMonitor was showing the lowest frequency of CPU was 2.2 GHz. I was playing with the ssdtPRGen.sh script further and eventually it worked out (not sure though) with E5-2670v2 setting. 


ssdtPRGen.sh script parameters that I succeeded:


sh ssdtPRGen.sh -cpus 2 -target 0 -l 32 -c 3


After that, the lowest frequency was correct (1.2 GHz) and full performance was regained (renders as expected, i.e. 3-5% faster than Win7, Geekbench showed almost 39k). That's it. 


Tests and reports by other users are more than welcome. 


Big thanks to author's tutorial, I wouldn't manage without it. 


I made at least 400 reboots with previous OS X versions in the past but power management never worked that well.  


 

 

 

 

What kexts did you use ? both in refi folder and /S/L/E ?

 

I see in your clover folder there is patches in config.plist for AICPUM, did you patch the kext or just use the clover patching? 

 

I have basically the same setup (3.91 bios though, Sierra 10.12.6) but with a pair of 2690 v1 cpus and I cannot for the life of me get this thing turn on PM..  I can get the cpu to scale back if I use nullcpupm but this is no use really.  

 

The rest of the z820 guide is spot on for patching DSDT and installing and setting up all that good stuff but the PM part I'm struggling with, no idea why I can't get this to work when I see reporting like this that it does on your Z620..   Feels like I tried everything and failing, I must be missing something stupid :)

 

I patched AICPUM with the perl patch, tried it also vanilla with clover patches, no joy

I try it was almost all ssdtPRGen flags it seems but pretty much the last run I used the same flags as you .. My ssdt looks same but for cpu diffs I guess..

I have tried in clover many an option from the one in Z820 guide, which would be my preference and many options up to what you have, you seem to have too many I think.  Enabling the c and p states like you have in the config.plist seems to only give me 2 states 28 and 29, which is max... 

 

Any info appreciated.. (from all working z620 owners) (hopefully one with 2690 v1 cpu too) :)

 

Cheers

Sorry about that. I have no experience in V1 cpus.

 

From my guide:

 

 

 

23- Follow instructions from here:

 

a- Follow step 1 i your cpu is V1 (Sandy Bridge E) . Skip step 1 if your cpu is v2 . It’s not needed for Ivy bridge E cpus. Go to step2

 


 

 

-Did you follow the step 1 of the link?? . for V1 you have the use the patch of step 1 and step 2. It's only download the patch and execute it.

-don't forget the bios setting. There is one menu specific for PM and it has to be enabled. Read the first part of the guide.

 

You don't need use nullpowermanegement.kext. It's a bad habit.  In some mb is needed to avoid KP.  But in our machine is completly useless.

Hey Bilbo,

 

Yes I followed it, still seems not to work.. thanks for replying and the guide .. awesome..

..and the bios setting?

 

Could you post the syntax to generate the ssdt? and ssdtPRGen version?

 

As general advice, don´t use any drop table function from clover. I think they are incompatible with ssdt generated by ssdtPRGen. In general, all options of KM of clover are useless.

Yes bios also.. pretty much the bios settings I had in place already. I'll check the drop table stuff as I am dropping cpupm and dmac.. sure I had it dropping nothing at one point also but never hurts to revisit.

 

 

Edit - I'll send the ssdt syntax when I get back to pc,. On phone typing this is just now.. for version currently it's 21.x but have used many from V12 to 14 to 15.x.

 

I think syntax will be -target 0 -cpu2 -l 32 -c 0 -x 0

 

But I have tried vanilla and many more with changing cputype panicking on boot.

 

 

Cheers

To extend my advice, don't use any option of PM section in clover.

 

Send me your clover folder via PM if you want. I can't promise anything, because I don't know z620 rigs. But maybe, just in case....

      THE GREAT GUIDE
      HIGH SIERRA + Z820

       
      ********
      10/07/2018
       
       
      *********************************************************************************
      ————————————————————————————————————————
      ————————————————————————————————————————
       
      (from El Capitan's guide)
      (from Sierra's guide)
       
      Introduction:
       
      Hi everybody. 
      Again, a new guide version, updated to High Sierra. I hope it will be useful for you all. This time, the update is easy. Basically, the 100% of Sierra’s guide is still valid for High Sierra. The guide has been updated to update links, kexts versions … etc, and some parts try to be more clear. Just there are some important topic to keep in mind:
       
      1. What's new?.
      There is a new and absolute important setting to install High Sierra. We have to activate “legacy ACPI cpu tables” in Advanced Section, in BIOS. Without this option enabled, we will get a KP. 
      This option changes completely the structure of the SSDT needed for PM. We have to get rid old SSDT versions, if you extracted them with this option disabled. And all SSDT generated by ssdtPRGen, too. And, if your DSDT has the “SSDT-1-CpuDef” code injected, (following my previous guides, to skip "No ACPI Processor declarations found in the DSDT!" error, (see PM section) ) you will have to delete that part, because the DSDT will cause a KP. A better method is described in this guide. No need of add strange code into DSDT.

       
      2.Can I use my old files from Sierra´s EFI folder?
      The most important, yes. You can keep your config.plist and your DSDT(see point N.1) … saving tons of time. You have to use the new drivers64Uefi files installed by new clover version, and update the kexts versions of main kexts. The specific kexts for our dear machine, USB3, Astek driver, remains in same version.Of course, I provide of all links and files (into my stuff folder) in this guide.
       
      3. So, do I Need repeat again every step of this guide?.
      If you comes from Sierra´s guide, no. After 1stboot and graphics divers install, you can use your previous files (see point 1.) reboot and jump directly to PM section. 
      For new users, Yes, sure.

      4. Consider any part of this guide open to discuss.
      If you see something wrong, or which could be improved, please, just say it, and I’ll fix it. English is not my native language. If you can’t understand some step, or something could be best written, please, just say it and I’ll fix it too
       

      FOR 26x7 and 26x3 USERS!!!. Finally, there a Fix to this models. It´s under test, but I think it should work. Check out FIRST the last section of this guide.
       
      5. And please, (this is for "anonymous" users) don't PM me with personalquestions. No need for that.Any question can be answered openly.
       
       
      Ok, let’s go.
       
       
       
      PART I
       
      1-BIOS SETUP
       
       
      This guide is for UEFI systems. This is not important to follow this guide except in Clover installation section. Keep in mind it to adapt some settings if you need use legacy-bios mode. 
       
      If you don’t need any special option, and you have been playing with options, reset the bios to default settings.Later, you will be able to change and test, if you need some specific option. The next section describe the essential options. 
       
      6. The main BIOS options are:
       
      In storage: 
      set ACHI mode (IMPORTANT).
       

       
       
      Set boot order. UEFI first, (for me), USB first and HD second. 
       


       
      Security : 
      Device Security: I like disable unused devices (scu controller and serial port). Optional.



       
      Disable Vt-d: Disabled. IMPORTANT. 
       

       

       
      Secure boot. Disabled (...to boot with non signed OS). 
      I use UEFI boot, but I keep legacy support active. This is optional.
       

       
       
      In Power :
      Set Runtimepower management to Enabled. This option will allow Power Management later. About the rest of options, I’m not sure of the impact in performance. Set them by default by the moment. Not important for the guide. Only remeber for further tests that with Pcie Performance Mode enabled, power boost is disabled. Idle Power Savings manage sleep policies.


       
       
      In Advanced:
       
      Set PXE, Storage and Video to EFI. (for me) , or legacy, as your want. If you have a graphic card non EFI-compliant, you can set video in Legacy, keeping an UEFI boot.
      Don’t forget set thunderbolt policy in Legacy mode.
       

       

       
      And Now, the essential setting for High Sierra: 
       
      -Enable “Legacy ACPI CPU Tables”
       


       

       

      _________________________________________________________________________________________________________________________________
       
       
       
      PART II:
       
      INSTALLATION
       
      7- MEDIA CREATION
       
      (This guide assume you have a MacOs running. I have no idea how do it on PC)
       
      -Important: Download HighSierra dmg only from Apple.Don´t use suspicious dmgs or Isos. It’s not longer available to search in Apple Store, since Mojave release. Go to this link, and click in “Get macOS high Sierra” (at mid of the page). It will open the apple store download link. The dmg is downloaded in /Applications folder. Let the file in Applications folder. (and keep one compressed copy for future attempts)

       
      -Format one USB stick with common settings:
       


       
      Go to erase tab, select GUID partition table in options, and Mac Os Extended (Journaled) as Filesystem. Name the partition as “USB”. Ok to Apply.   
      On a terminal window, type (copy and paste) :  
      sudo /Applications/Install\ macOS\ High\ Sierra.app/Contents/Resources/createinstallmedia --volume /Volumes/USB --applicationpath /Applications/Install\ macOS\ High\ Sierra.app --nointeraction  
      Enter and type your admin password. It will take 10-15 minutes. (When it finish, you’ll see the prompt again)  
      8. INSTALLING CLOVER.
       
      -Download Clover from here. Version used to make this guide: Clover_v2.4k_r4658.
      -Download Clover Configurator from here. It makes easier edit config.plist file and we can use a lot of clover features easily. Now there is a “global edition”
      -Download plisteditor pro demo for edit info.plist files.
      -Download my High Sierra stuff folder. (at the end of the guide)
      -Additional tools: One tool for install kexts, fix permission and rebuild cache. I use Kext helper from rampage’s dmg, although I need always force quit. I don´t like the rest of utilities. This is a personal option. Also you can download  EFI mounter (from download sections of this site). CloverConfigurator mounts EFI too, but maybe with this utility is easier.
       
      -Install Clover in the USB. On first screen, don’t forget change the install location in order to do not install on your Internal HD. Select your USB stick.
      Click on Customize. Choose “Install for UEFI booting only” and “Install Clover in the ESP” as main options (if your system is UEFI-based) This is optional: choose your favorite Theme. In Drivers64UEFI select: Now is longer section. It´s only because is more exact showing the drivers installed. We have to keep selected the default options and add the same additional drivers. Keep in mind two important things:                   -There is a new driver, APFS driver, for the “new” filesystem. This driver is now essential, in order to allow clover “see” HDs formatted with this FS. It´s activated by default. 
                       -The OSxAptiopnFix2Drv has a new version, v3.
                ... The conclusion of this long explanation, is that we have to add to the default selection of drivers: 
       
                                - EmuVariableUefi-64
                               - OsxAptionFix3Drv
       

      Let the rest of option unselected and Click on Install.
       
       
      9- CONFIGURE CLOVER

      When clover finishes, it will mount EFI partition. Time to modify it. You’ll find all necessary files in my folder. There are three things to modify: config.plist, drivers, and kexts
       
      9.1 Config.plist
       
      The default config.plist is not useful for us. Replace it by mine (folder n.2)
      But take a look to options (with clover configurator) to understand my options in order to be able to adapt them for your specs or your preferences. It’s a basic config.plist. I could add more options or fixes. but is a good idea install with minimum options. 
       
           Acpi section.
          All fixes in ACPI section has been removed except some minor fixes in 2 subsection, smart ups option, etc. SmartUps it’s not important now, but it will be later. So I prefer activate this option. 
          The most important, The rename usb devices patches are included. 
       
          

          Boot section
          Bootflags needed are only -v and npci=0x2000. Of course -v is optional only to see the boot process. You can deactivate it when you finish.

      They are:

           
       
      These are the versions Updated since Sierra´s guide.
       
      FakeSMC.kext. If you remember, I have some unexpected KP due to fake smc sensors. Well, I have searched a bit about this, and testing. The main topic is keep the fake smc version and sensors kext of same version or branch. There are several branchs developing              different versions (slice, rehabman, kozleck, etc), after test, and test, I think the most stables and those which gives me best sensor readings is kozeck version. I attach the v1440 from kozleck. In this step I only use FakeSMC kext, withput sensors kexts. Anyway, if you have a better version, use it. Just, don´t forget no use the sensors Kexts.   
      VoodooTSCync.kext, to avoid boot with -x (from rampagdev, dual cpu dmg). You’ll find several versions into my folder.I haven’t noticed any change using the generic or the specific version. I think that is not important for our platform.                  The customize method is:

       

       
               Anyway, I provided the generic version and customized versions for every cpu.

       
      IntelMausiEthernet.kext . Kext for the ethernet card from rehabman. (2018-0424version). It will allow have internet connection on first boot.  AppleIntelE1000e.kext. Kext for ethernet card from here (2017-10-18 version). (Change of  server if you have problems downloading) <<<< update. Use this better than IntelMausiEthernet.kext
       
      UsbInjectall, for USB2 from rehabman( 2018-0822version)  
      And add to /EFI/CLOVER/Kexts/others
       
       

       
       
      Lilu kext (from here, 1.2.7version)  
      WhateverGreen.kext (from here, 1.2.2 version) old NvidiaGraphicsFixup proyect has been integrated into this proyect. It's useful for nvidia and amd graphics cards  
      This couple of kexts avoid black screen booting with 6,1 smbios. Is quite important keep in mind the versions of these kexts keeping the right versions among this kexts. Prior to update some of them, you have to check in original websites if it's is compatible with the rest. These versions are ready to work with 10.13.6. 
       
      Thats all. We have our usb installer ready. Copy in a folder all stuff necessary to repeat the process and copy it to the USB stick. You will have it available after first boot.
       
      Reboot from the USB stick and install High Sierra. 

       
      10- INSTALLATION

       
      Some advices:
           -Use only USB2 ports, preferably the front USB2 port.
           -Don’t use USB hubs, or cable extenders… (personal issues)
           -Unplug any other usb device
           -Be sure that you have plugged your internal sata drive to one of the two internal achi sata controller.
       

       
           -The boot process may be slow, (and with terrible and apocalyptic errors). Be patient
           -Maybe, the boot stucks with the error “consideredRebuildKernel …. blabla”. Just reboot again.
           -If you have two monitors, shutdown one can help with graphical errors.
           -Plug your graphic card in PCI Slot 2.
           -For inexperienced users: On first screen, go to disk utility and erase the Volume. (APFS and GPT). Quit the utility and return to first screen. Choose Install.
           -The process is splitted in two steps. The first step promises take only 4 or 5minutes … and now, it’s true!!!. It will take4 or 5 minutes(with a SSD).
           -After this first reboot, in clover boot screen, you will see more partitions than expected. APFS file system manage more partitions in a more complex way (physical layer, logical layer… bla, bla). Select  the new internal HighSierra boot installer partition, not the usb installer. It will finish the  process. This step, takes 10-15min aprox (using a SSD).
       
      Note.I had some unexpected reboot in this step. Only re-trying if you have it also.
       
      -To boot again after installation, keep booting from USB , ant then choose internal HD as clover boot screen.
       
       
      ---------------------------------------------------------------------------------------------------------------------------------
       
       
       
      PART III:
       
      FIRST BOOT
       
      11. Optional updates.
      Finally, we are on High Sierra's Dektop. The Mac os Version is 17G65. In the date of this guide (oct/2018) is the last version. (there is an optional update only for real macbook laptops). For future security updates, this is the moment to update. Set up the internet options and update the system, but remember check if the Lilu and whatevergreen kexts are compatible or if you need use a new version, or you will geta KP or a black screen on boot. Update using the update app, reboot, and wait for the update installation.
       
      12- Install Clover.
      On first reboot, install clover again on HDD, repeating same process and same options than with the USB installer, but keep in mind you have to add some options on clover’s screen install:
       


       

           -Install RC scripts on target volume
           -Optional RC scripts
           -Install Clover Preference Panel.

      …and install clovermanager.app. This is optional but it’s the best way to manage the themes and find a good theme. I provide of one nice High Sierra Theme and the Bootcamp theme. Of course, left this for later. 
       
      Install clover and add same files used on the USB: config.plist , hfsplus driver and kexts. Reboot. You can now extract the USB installer and reboot from the internal HDD.
      After boot, go to clover preference panel and set it to auto mount EFI partition. It will be useful along this process. Disable this when you finish and you get stable your system.

      Hey guys,
       
      I'm really hoping someone has the experience and ability to help me iron out the last remaining issue on my build.  
       
      The motherboard is: Gigabyte Z370 Aorus Gaming 7 and I'm running a Alpine Ridge thunderbolt card (Revision 2).   I've gotten everything working for the most part with the exception of Thunderbolt hotplug.  This is the last piece of the puzzle.  I've tried so many different DSDT/SSDT's, cable plugged in, and unplugged, without any luck at all. 
      I've managed to get my Focusrite Clarett 8Pre Thunderbolt working and it's showing up under the PCI section.  It works great, until I shut the device off and turn it back on.  I'd really like to try to get this hotplug issue sorted out, but I've had absolutely no luck so far.
       
      I've managed to get the Alpine Ridge NHI and USB controllers showing up in the PCI section too, but for some reason, the USB lists a bunch of ',,,,,,,,' after the name. 
       
       
      I'll be the first to admit - I don't really know a whole lot about what I'm doing with this stuff, but I've attached relevant files in hopes someone more experienced and knowledable can help me get this working.  
       
      Thanks guys!

      Hello! My internal SSD lifetime is running out so I'm thinking how to upgrade it. I don't want to replace it with slow Sata SSD so I want to buy OWCMercury Helios and install new nvme fast ssd, but I won't be able to boot from it using standard boot loader.... Is it possible to boot nvme ssd using Clover on real iMac?
