npub1pu3ryltaaqjym9gj5fpcv623edtfh2vuvrtcd8pz75p6nlyt0nrqyq8r76 (npub1pu3…8r76) It's hard to tell about prevalence from the outside, but I feel like getting a part that hadn't undergone sufficient manufacturing testing used to be extremely rare.
The cases I used to hear about (25 years ago) were things like, you overclock and overvolt your CPU for a year and then it starts being unstable, but those CPUs were never designed to be used that way, whereas now it's expected that many users will get "gaming" (or w/e) boards that do this and the parts won't work.
