I have three systems in my home, all running BG3 for family members and none of them have an issue so this is not an "AMD" issue. This could be background software related issues.
I have witnessed a Sapphire RX 6800 XT Nitro+ that would reliably crash the system the moment its junction temperature reached 110°C (not 109, not 111, always precisely 110). The initial symptoms looked a lot like what's described in this thread: most games were totally fine, but some games (the ones pushing this particular part of the GPU a little further) would cause a system crash after some play time. The issue would also appear if the card was moved into a system that was perfectly before.
I concede that this is not a hard proof of an issue in the GPU BIOS (we could not attempt an update to test with a newer version). But given how repeatable the issue was, and the fact that the card was part of one of the first production batches, I remain convinced that this was a bug in the thermal throttling mechanism.
For the chipset issue, I have also been able to fully and reliably reproduce the issue on completely distinct B550-based configurations on Windows, Linux, and FreeBSD (also tested with various BIOS versions). That was about 7 months ago.
As much as I want to support the underdog, gotta say I have not been impressed with AMD's QA those last few years.
