Ryzentosh suddenly randomly crashing after 30-60min

Hi everyone,

I made 2 days ago my first Ryzentosh based on OpenCore running macOS Big Sur and everything seems to work pretty well, until the screen suddenly turn black and the PC starts rebooting.

First, here's my config (a bit weird because there's 2 different GPU in my system because of the lack of Webdrivers on Big Sur) :

  • CPU : Ryzen 5 3600X
  • Motherboard : ROG X570-E Gaming
  • 16Gb 3200mhz DDR4
  • GTX 690 (Disabled when on Windows using device manager to avoid conflicts with the second GPU)
  • GTX 1070 : Disabled using a SSDT for macOS to use the natively supported Kepler GPU instead, so only used when booting on Windows

I can use the computer for 30 min, sometimes almost an hour, but at a given time macOS completely stops and the PC just reboots. I'm using the verbose "-v" argument in my boot flags and tried to look at the logs in the console app, but I can't figure out what's wrong.

A copy of my system.log : https://drive.google.com/file/d/16A8Asr9dIeSYDLZLW73qZS6EQy2XMFj-/view?usp=sharing

I still am a kind of newbie so ask me if you more infos / logging files are needed.
Thanks !
