Question - 5800X fails single core cycler test

Bought the chip in Nov. 2020 for my main/daily rig and it's been running relatively smooth since then. I had a system crash with the following reboot saying there was no drive. Don't know what fixed it but 3rd or 4th boot it came back to life. I had a screen flicker about a week or so ago but...

I tried this on a 3900x that has run prime95, Rosetta, WCG and every other software and it failed also, even though its never failed in real life on any real software. I am sure anyone can make software to make CPU's fail, but SOB didn't even fail, and its very picky. I think its software designed to make it fail... Or not really fail, just report that it did. Regardless, this is a BS test IMO. I had 2 of 24 cpu's fail at stock.

Edit: if you want something no software can break, run it on a server, that is what they are for. For a home computer, you can make them fail, not a server.

This cycler seems to run Prime95, which has the same core as PrimeGrid. The difference is it runs each core at maximum turbo. Turn down your turbo and you should be fine.

But, yes, that means the single-core turbo is set too high.

I never run anything in single core.....
