My 14900KS is burned. I can send it back but I don't know what to do.

I am Japanese and my primary language is Japanese.

I got a crash when running OCCT CPU EXTREME with this setting

Then I checked to make sure it was burned.

Interesting that this kind of damage could happen with default settings. How long were you stress testing the CPU before it incurred this damage? Does it still operate?

[Eunice-Yunisu]

It's a short time, about 10 minutes.

[Norman_Trashboat]

Just to clarify, this was done in one single run of OCCT? The one posted in the video? 

Looking at it, you oblierated your CPU. TJMax for 14900KS is 100C, you were 15% over that threshold for a very long time and a whole lot of clock cycles. 

Was this setting enabled by default?

[Eunice-Yunisu]

OCCT was run multiple times, taking a total of about 10 minutes.

Although it depends on the motherboard, the default settings are Tjmax 100℃ and Fast Throttle Threshold 107℃.
