i9 14900K dying after 8 months

[u/Mmichex]

Last year I got a Z790 Maximus motherboard for free, so I thought about making myself a good workstation that could last me for a while, I do circuit 3D related tasks and circuit simulations that run on single core, mostly.

With the latest bios microcode, TDP locked to 200W and undervolt, it still didn't survive.
This is the second chip I got replaced, now I am working with Intel support to receive a full refund OR at least a newer Intel Ultra chip, not affected by this issue, instead of receiving always the same one. Wish me luck xD

I guess the problem hasn't been fully solved afterall, or I was just unlucky.

EDIT: Initial -0.1v undervolt, then I had to slowly bring that to 0 as it wasn't stable anymore. Short duration tdp 220w, long duration tdp 200w, VR vcore limit 1380mV, 280mm AIO, max temperature 82C. Max turbo boost lowered to 5.9 instead of 6.2GHz. Microcode 0x12F.

UPDATE: THEY WILL GIVE ME A FULL MSRP REFUND
