I tried everything listed in that link and many other things found here and there but I could not get PM working on my Ivy bridge since Ventura. It was working great before that.

It was working great before that.

Currently, I am suffering from a phenomenon that AGPM does not work properly on Catalina.
EDIT:
It is now operating by Opencore 0.8.9 and #15 instructions.

Hey I have ventura on an x58 sabertooth legacy with i7-960 and rx 570 gpu. What I did was just creating an opencore efi with oclp choosing macpro5,1 on an usb drive. Then I just took most kexts cryptexfixup, some avx and also power management and also the kext patches and put the into my config. Now I have some kind of power management with idle and boost freq. Everything works smooth, except hevc and usb1.1 devices.

Things to know when trying to run macOS Ventura on Ivy Bridge:

• Guide for fixing legacy CPU power Management in Ventura:https://github.com/5T33Z0/OC-Little...abling-acpi-power-management-in-macos-ventura
• And of course you need Post Install Root Patches from OCLP if you need on-board graphics (≤ 13.2.1)
• Don't install or update to 13.3 beta. Graphic Drivers from OCLP won't work (boot will be stuck in the first third of the boot progress). You can use the ltest version of OCLP for re-installing the Intel HD 4000 drivers on macOS 13.4

I would like to share my Ivy Bridge + Ventura 13.3.1 and dGPU is RX560.

Hey, any tips? I'm wondering if you had to use OCLP or not. Can you share your steps? Thanks

My step1. Make sure the efi could run macOS 12 Monterey at ivy bridge + rx560.

step2. download and add the CryptexFixup to kexts folder and config.plist.

step3. config.plist
boot-args add -amd_no_dgpu_accel -cryptbeta amfi=0x80 ipc_control_port_options=0 amfi_get_out_of_my_way=1
Disable SIP: csr-active-config: 03080000
SecureBootModel: Disabled
Dmgloading: any

step4. Install macOS Ventura
step5. Login Ventura and download OCLP. Root Patch for dGPU and finally boot-args remove -amd_no_dgpu_accel

reboot and done!
Thanks.
