Well killed may be a strong word, severely degraded is probably more appropriate.
My CPU is a i7 6850k @ 4.2GHz core 1.275v \ 3.2GHz cache 1.15v installed in an MSI Godlike Gaming Carbon will a full custom hardline water setup. Last night I was reading some threads on what clocks and voltages others were running and decided to give 4.4GHz @ 1.32v core a try, I left it for a couple hours to run 6 threads of Linx which failed after an hour and a half or so; core temperatures peaked at about 78°C, fluid temperature was ~31°C depending on how reliable the XSPC thermistor is (pre radiator).
Set it back to my 10 hour stable small FFT prime profile, only to instacrash with a stop code on boot.
So I'm thinking cool, no worries; that's why I do a system image before tinkering in case I corrupt something...
Except it is now crashing even when booting from a Windows 10 DVD. I'm not an expert but I do have basic troubleshooting down, even a clean cleared CMOS is crashing.
I finally managed to get it back stable by clocking it down to 2GHz at 1.28v, but it looks like she's done for.
I also decided this is a good excuse to get a 6900K (I know, yes I do threaded work too), in the mean time I'm going to see if Intel will swap my CPU and sell the replacement should I be so lucky. No I don't have their overclockers warranty and I don't plan on being dishonest about the circumstances.
I'm not looking for advice so much as I wanted to share my experience with the community, mostly as an example in case anyone else was thinking of or is running voltages in this range.
TL;DR: I killed Broadwell-E with only ~1.32v (give or take a few mv for load line calibration and such).
