That reminds me of how I accidentally tracked memory issue to the failing power supply.

I noticed (after some windows bluescreen) on memtest that the memory is showing some errors. Ordered another 16GB pair, replaced it and.... the problem persisted.

Suspecting something with motherboard I just chalked it to something with mobo and pretty much said "well I'm not replacing mobo now, it will have to wait for next hardware refresh. Gaming PC so no big deal. And now I had 32 GB of RAM in PC.

Weirdly enough, problem only happened when running on multi-core memory test.

Cue ~1 year after and my power supply just... died. Guessing bad caps I just ordered another and thought nothing of it. On a whim I ran memtest and....

nothing. All fixed. Repeated few times and it was just fine, no bluescreen for ~ 2 years now too.

I definitely want to get next machine with ECC but the DDR4 consumer ECC situation looks... weird. I'm not sure whether I should be happy with on-chip ECC, I'd really prefer to have whole CPU-memory pipe ECCed
