i9-9900k is dead after 6 months used. Would like to understand and know why and what killed it.

[Zaydez]

I have been using a i9-9900k in my pc for the past 6 months flawlessly, until then it was dead yesterday during half-way used of my pc. My pc went freeze and I had to forced shut down it, and it was looping boot with BSOD message whea_uncorrectable_error. I have tried to update my bios version to see if this solves the issue, until then pc will never boot up again.

 

How do I find out the i9-9900k that is the cause of this BSOD error message and no booting again after updating bios version:

- Swapped to another processor to check if the pc boots up, and it does.

- with i9-9900k on the board, motherboard's Onboard LED stuck at "VGA" part even with GPU has taken off.

 

I would like to find out and understand what could be the possible causes that killed the i9-9900k so quick.

 

Additional information:

- Never over-clocked the processor in the past 6 months

- Motherboard: Asus Rog Strix z390-e

- CPU cooler: Corsair H110i Platinium

- GPU: Asus Rog Strix GTX1080

- PSU: Corsair RM750i Gold certified

- RAM: 32gb Corsair Vengence LPX

 

Would appreciate if someone could drop comments to let me know what are the possibilities. Thank you!

If it was always cooled properly and you weren't pumping tons of voltage through it, I'm going to go with: shit luck.

RMA it and carry on.

 

Welcome to the forum.

Ya this sounds like just a bad luck of the draw. Warranty exists for reasons just like this, as said above, RMA and move on

try putting the cpu in the other boards. the board you'be been using is pretty high quality so it shouldn't have any trouble with the cpu. also it really sounds like something has gone extremely unlucky. perhaps a voltage spike somehow? doesn't seem right anyway though.

best of luck with RMA

Might have been a bad MB, could have been a bad RAM stick, could have been a bad PSU, a bad HDD/SSD... perhaps something in the PCIe bus... contamination on the LGA?  Bent pin? this is the trouble with having a single computer for diagnostics. Whatever it was it's something hardware related. that's what WHEA is. Windows Hardware Error Architecture. without more to go on than that, i'm afraid we'd just be guessing. and if you don't have other hardware you can test with, i'm afraid RMA is all you're left with.

This has happened to random 9900K's and 8700K's over the last few years.  It's very rare (then again, people here, reddit or OCN/hardocp etc make up a very tiny percentage of users, but overall sample size can be extrapolated outwards), but there were a few threads about this on Hardforum and reddit some time back about 9900K's dying suddenly after a few weeks (even others about 8700K).

 

No one knows what happened either.  It's unknown whether a core or low level cache just decided to up and die, whether the board(s) suddenly threw tons of voltage into the chip randomly, or whether the IMC died or not.  WHEA_Uncorrectable_error (Stop 0x124) is usually always core or cache related, not IMC, afaik.

 

What happens if you set your core to x47 (stock) and set your cache ratio to x36?

Does the system boot now?  If it does, can it run prime95 29.8 build 6, with AVX disabled, small FFT preset (no one should be using 26.6 now, 29.8 build 6 lets you disable AVX in the options now).

So guys, i have RMA-ed my i9 9900k, and apparently intel replied out of stock on the unit right now. What can I do?

I assume that would be for you and intel to sort out. what options have they given you?
