Hi, I just built a new rig with following parts:

https://pcpartpicker.com/list/WxKZ8Y

After done setting up i tried to OC my core to 5ghz, according to this guy https://youtu.be/CoUtA7DKXhU

unfortunately once I started stress test on CPU it just get heat up super fast nearing to 100C and auto shut down in any of benchmarking tests

I tried stressing again after changing the thermal paste on cpu to kryonaut (was stock thermal paste from NZXT) and still overheat.

Hence, I tried to tune down the overclock by setting CPU Core Ratio to 48, making it achieving only 4.8ghz

Tried on stress tests again (CPU-Z, XTU, 3D Mark, Cinebench) This time all passed without auto shutdown but the temperature still hits over 90 once awhile, which i think it is still unhealthy?

So, is the only option is delidding? or there might be any setup problem?

Bro, not all chip can do 5ghz without hitting temp limit for high voltage, like 10% chance only. Also u need better water cooling also, even Noctua also no chance

4.8ghz already great

Whats your vcore?
I set mine at 4.7ghz, 1.17v, running max 66c on AIDA64 cpu stress test.

1. debauer vids are too generally and its totally based on his sample. I wouldnt put much worth to it.
2. Know ure cpu/mobo/ram.
a). 8700k .. have u tested your stock vid and see whats the scaling like.
b) strix had issues with voltage loadline issue during release..have they solved it yet?
c) test your rams first.

define the steps on a systematic way how u deduced that 4.8ghz is your max stable.

also theres a thing called avx offset.

better try with custom water cooling before delidding it... but again.. it's not cost effective...

should be normal cause 8700k heats up easily a lot. even water cooler cant manage to cool well too
