Hard crashing after high CPU load (macOS 11.5, OpenCore 0.7.1 Debug)

Hey there! It's my first time posting but I'm hoping you lovely folks can give me a hand here.

I recently completed building my video editing system. It's running an i9-9900k on a Strip Z370-F board and using an RX6800 as a GPU.
I can boot perfectly into macOS, everything is running fine and all until I put the system under load. Within 3 minutes of coming out of that high load period, the system hard crashes. I have 3 different error reports, all saying different stuff but all generated from the same event; Render in Resolve and then hard crash when trying to do anything else.

I'm running a MacPro7,1 SMBIOS (which I am aware isn't recommended, however I had issues with H264 encoding using the iMac19,1 SMBIOS), I've mapped my USB ports and have fixed power management. I have also gone through the MMIOWhitelisting process and ensured that my memory map is correct. If anyone else needs any other specs/details, please ask! I'm happy to share my EFI or any logs that I can find. What I am noticing in the Console applications is a large number of VTDecoderXPCService crashes, but I'm not too sure if they're linked.

Thanks!
Caylem.

Had another two crashes so far, one related to an exFAT drive causing a kernel panic and the other a nice ol' bog-standard type 14 page fault error. Attaching logs for reference. I've also got a bunch of crashes in the console to do with WindowServer.

assume you have an exfat drive plugged into your machine?

I did, but that has since been pulled. Same behaviour, got the second page fault type=14 error as shown above in the attached files.

does it still crash out when you use iMac19,1 system definition?

It would crash out frequently however when I fixed power management and mapped USB ports, it stopped.
The reason I couldn't use that system definition is because H264 renders would become garbled when hardware accelerated. I mean really garbled. When I switched to using MacPro7,1 that all stopped.

I did yes.
I am willing to completely reconfigure the system with your advice should you think I’ll have a better time on iMac19,1?

i think that would be best

if you go back to iMac19,1, don't forget to edit your usbports.kext info.plist and make sure it says iMac19,1 inside
