A help for x79 (C602) users

[viniciusmi00]

For all users of x79 (C602) cards, who are having trouble getting Catalina and BigSur to work with Clover or OpenCore.

After spending days trying to get my x79 stop giving Kernel Panic in BS I was successful with a Patch. I realized that there are still people with difficulties in Catalina too, so I will leave some tips that can help you to get Catalina and BigSur.

For Power Management work in Catalina and BigSur there is a Patch in Kernel and Kext Patches, in KextsToPatch:

Name*                                                                                                       Find*.                      Replace*                     Comment

com.apple.driver.AppleIntelCPUPowerManagement                        7511B9                   EB11B9                        10.15, 11

com.apple.driver.AppleIntelCPUPowerManagement                        3E7538                   3E9090                         10.15, 11

Like a:

For BigSur not to get a Kernel Panic in IOPCIFamily there is a Patch in the ACPI, in DSDT.

Patches                                                                           Find*.                                                  Replace* 

UNC0 _HID to XHID                                                       554E43 30085F48 4944                   554E43 30085848 4944       

UNC1 _HID to XHID - UNC1 to Dual CPU                   554E43 31085F48 4944                   554E43 31085848 4944
Note*: UNC1 only required for cards with 2 processors

Like a:

You can use my EFI as an example, just stay tuned as I removed some essential files to get smaller.

EFI.zip

 

Note: In CPU > Type, you can remove these codes and put your CPU's code to appear correctly in "About this Mac"

To find the code of your CPU, just open the IOJones App and find the reference for your CPU (probably above the AppleACPICPU). The code for your cpu is found in the "cpu-type" property. Just reverse the order by placing the last 2 numbers first and the first two numbers last.

Hi, first of all, thanks for the help.

I am having problems updating to BigSur and I believe a relationship with what you comment.

First of all I do not load the AppleIntelCPUPowerManagement, I understand that it is only used on laptops.

The second thing is that I am using OpenCore 0.6.3 and a patched DDST from Marl0n, initially I used the SSDT-UNC.aml from the official opencore guide but same Kernel Panic in IOPCIFamily .

I have included the UNC0 _HID to XHID patch but continue with the Panic  .

@Hector Melendez I don't know what it can be, I'm also not good with OpenCore. Mine is functional, see if it can help you.

I'm also not getting my USB 3.0 to work. The "GenericUSBXHCI.kext" kext is not working on Big Sur. I am looking for a solution, but so far I haven't found it. Is your USB 3.0 also controlled by Asmedia ASM 1042?

I abandoned OpenCore, I had some problems. I'm just using Clover. See if my EFi folder solves your problem.

Note: I already changed the SMBIOS serial before I sent you the Clover. You can test this folder without having to change the SMBIOS serial.

Hi guys. I'm having a hard time with a hp z820. It has a dual e5-2670 and been struggling for days. I followed the dortiana guide for sandy bridge e but I cannot get it to load successfully. I have a ati 570 on it.

Using oc 0.6.4 which I attach just in case.

Thanks in advance.

Hey guys,

I got PM to work fully in OC, I followed the official OC guide and generated the SSDT with Piker's script and set up the Omni Patch. Config bit for OC attached, as well as Output from AppleIntelnfo

Hi mate, do you have x86platformplugin loaded in ioregistry?

Thanks for sharing the .plist. Do you mind sharing the ssdt so I can compare with mine? 

Thanks in advance.

[JakubW]

Hey, no the x86platformplugin plugin isn't loaded, it wouldn't load anyway, just the kext patches

And here is the SSDT, nothing big, most of the job was done with Pikers script.

got improvements on SSDT and loading x86 platform plugin, now it is loading correctly and Mac single core turbo is displayed correctly. To generate it I sues the script with following attributes 

./ssdtPRGen.sh -p 'E5-2670' -x 1 -target 0 -c 3 -cpus 1 -l 8 -mode custom -d 3

You need to extract amps from your motherboard and copy APIC.aml to your desktop.

[kundaria]

it looks like all are testing on catalina 10.15.7 

its not working on BigSur 11.2.3

i am trying since last two weeks not a single patch of AppleIntelCPUPowerManagement on x79 is working on BigSur 11.2.3

[osamamattar]

I make my ssdt in windows using SSDTTime-master I just want to know how to change the cpu type to i7 3820 in OpenCore board is Asus p9 x79 rx 570
