Cpus dying more often now?

[Justintime]

i5 8500 - Was in some random HP Deskpro, BSODs - Critical process died, IRQ less than blah blah etc.. windows won't install without bsods when it did manage to complete would lock up etc... tried memory, gpu etc.. nothing. Tried a new 8500 and all problems gone. put the old one back, bsods. Tried in a different board with more control and noted with turbo boost off cpu was 100% stable, enabled and it went back to bsod country.

9400F - Same thing really except disabling multi core solved it so probably a bad core.

9900 non K - Won't run dual channel memory in any board with any memory, usb transfers in the 30-50mb/sec range but with good cpu in the 100mb + range with same stick and files.

9700K - Very random POST and lock up imminent but worked fine otherwise with no BSOD etc.. lol, cleaned it to hell but same result on multiple boards.

i5 7500 - Died randomly in clients pc, new cpu works fine. Never seen that amount of cpus die in a decade muchless a year! Seen a few Ryzen ones died too but those are mostly DOA, are Cpus much more fragile these days or what? Most of these cpus are non overclocked stock ones too.

Oh yeah work with few clients who have hundreds of Coffee, Kabylake etc.. with no issues but i hardly look to the cpu being the fault at first these just surprised me being they came from such mundane scenarios too lol

most likely mobo socket warping or dodgey pins in board? maybe reinstalling cpu would have had same effect as new cpu?

Different boards, same results.. new cpu sorted it every time. I even compared to capacitors/smds on the back etc.. to see if anything was missing.

The only CPU I have had die was down to operator error. Had been up all night sorting out my Duron 900, a friend came around and distracted me. Put the system back together and fired it up, could hear a random ticking sound, it was the processor slowly blowing itself to bits as I had forgotten to mount the heat sink, at least it meant I could now get an Athlon 1gHz.

ugh i'll admit to cracking the odd core with the mounting systems back in those days. Used to build pcs weekly for sale so saw a lot of cpus and those first generation ceramic body Socket A's were super fragile, i was accustomed to PIII durability! Chipped the odd core now and then but seems it was only substrate damage, probably lost 2 or 3 to actual core cracking.

You might not have realised this but buying the non overclockable CPU's you have increased your chances of getting failure down the road. These CPU's are the lower binned ones that don't make the cut and are poorer silicon than the CPU's that go on to become 'K' CPU's.

That being said, you do seem mightily unlucky to have had so many CPU's die on you! Have you been breaking any mirrors, walking under ladders or opening umbrellas inside your house in the last few years?

Not my cpus personally, i still do minor pc repair on word of mouth, used to do it for a living in another lifetime but no longer.

I've owned or built PC's for almost 30 years now, Never had a duff CPU personally. When I was selling them many moons ago, no end of problems. They were mainly Cryix based PC's

Cooling too, Cyrix cpus ran hot but heatsink technology was behind imo for what was really needed.
