Post-installation Tweaking/final touches.


May 4, 2020
Hi all,

I have to say my Ryzentosh is running great. Please see link at the end to my success story page with all the specs in details.

  • CPU: Ryzen 7 3700X
  • Motherboard: Asus Rog Strix x470i
  • Graphics: VGA Sapphire Radeon RX 5700 XT NITRO+
  • Case: NZXT H200
  • Wifi-Bluetooth: Bcm94352z. (I was meant to order the Bcm94360NG but made a mistake on Ali express with selecting the correct type. Kext are very easy to help activate the card)
  • Installed: Big Sur 11.2.2 | Windows 10 Pro
  • Bootloader: Opencore 0.6.6
I am trying to update my ACPI for my own build and add some corrections

SSDT-EC-USBX.aml - AMD EC controller updated as guide dortania.
SSDT-PLUG.aml - CPU power management, I do not know if this is necessary... please if someone could advise.
SSDT-RHUB - Fixing USB controller. This is working fine in combination with my USBmapping kext.
SSDT-SBUS-MCHC.aml - SMbus fix. Seems it is not working correctly, also added a screenshot with the terminal command to check.

When I am using the prebuilt ssdt - SSDT-EC-USBX-DESKTOP Ryzentosh is running fine. No crashing or freezing.
Now wanting to tweak with the above combination it seems to freeze and crash. I have added all the ACPI in the attached, as well as, DSDT dump plus some screenshots to show that I think I have built the ACPI correctly. There is also quite a time gab before the actual boot log starts...

Also, IRQ conflicts, How can I know if there are any? I added HPET for possible info here...

Anyway, I am just trying to reach those final touches to have everything working.
