Can anyone verify if my P-core 3 is defected? - i9 -14900K

[Khoa]

This is a 2024 freshly bought i9-14900K - bought it in June

I just got the PC back from the retailer to re-paste the CPU and clean the dust

Lately I got crashed while playing warthunder with 3-4 chrome tabs opening

Things got more often when I see throttling 'YES' at P-core 3 right after the crashes. Simultaneously, my chrome tabs also got crashed.

Here is the attached photo in Hwinfo under light load after the cleanup and paste-reapplied.

Thank you for your assistance.

Best regards,

Khoa

This is sometime later ... P-core 3 at 70C

Hi @Khoa 

It looks odd, but theoretically you could get a single core boost affecting only one or two proffered cores.

I see that you have very high voltages as well. Having that behavior would definitely cause instability and risk of degrading.

Could you limit the max frequency in BIOS as an experiment?

[Khoa]

can you tell how? bios setting varies accros brands

I'm using

PRO Z790-S WIFI

MSI, right?

Try the per P-core ratio limit.

[aCNuser]

use Prime95 small ffts test

and see which core fails, then manually down the core ratio for that core

Yes if it does not meet advertised standards , it is 100% defective. 

RMA it. And in august again as they claim from then on there will be a fix.
