I feel so justified for doubling down on Zen 3, and replacing my dead R9 5900X with an R9 5900XT lol

I'm getting worried, 'cause I've got the same. What killed yours?

[–] ipkpjersi@lemmy.ml 3 points 14 hours ago (1 children)

Bad luck. I started getting random reboots, the reboots started happening more and more frequently. I tried a few kits of spare RAM I had laying around, reboots kept happening. I replaced the PSU with a brand new one because mine was a decade old, reboots persisted. I replaced the CPU on a whim (with an upgrade if it was fine), problem went away entirely, not a single reboot since.

That's strange - I had some of the same symptoms and it ended up being a completely different thing - a dying (and then eventually completely dead) SSD (the Phison controller fiasco).

Other than that the CPU itself seems fine and it's only shown very minor degradation over the 4-5 years I've had it - i.e. it used to boost up to 4975 or 4950 single core, now it only goes up to about 4900 (no PBO, no CO); and I've also had to fix the SoC voltage because of the memory - but I haven't touched that in like 3 years, so not sure it's even degradation.

Yeah I tried increasing voltage, decreasing voltage, resetting BIOS to default settings, etc. I tried everything you could think of but nothing helped.

I did see a post on reddit from someone else with the same MCE hardware errors in Linux that I was getting, with the same random rebooting, and their 5900X ended up dying too.
