@kernellogger I have doubts it's really the memory tbh, I see from prior logs it has happened in the past (these mce reports) but it didn't segfault things like it has now...
I am seeing sudden temperature spikes when compiling with all 32 cores (i9-14900k) but no such error when stress-ng'ing.
BTW I have 192 GB of RAM (don't ask me why I can't answer) which is the max the mobo can support so possibly a cause of weirdness... :>)
