Hi, so I OCed my 8086K to 5GHZ@1.28V and it's working just fine. I have a cooler Noctua NH-U14S and my temps don't go over 70°C while gaming and over 84°C while stresstesting with Prime 95 26.6. I just want to ask if i would be able to go higher if I delid it. I don't want to go over 70°C when gaming. And second question about silicon lottery. Is my chip average, better or worse than average? I have seen i7 8700K doing 5GHZ@1.2V . Thanks for answers and also you can share your OC result of 8086K or 8700K. :)

Every chip is different even though the 8086s are supposed to generally be better OCers vs other chips. I wouldn't risk a delid on a chip like that unless I was planning on trying to break an OC record or something. Frankly if I had a chip like that I wouldn't even be OCing it at this point as it should handle most anything you'd be throwing at it with relative ease. I will also tell you that my 9700k wasn't stable at 1.2v stock, so yeah that's the silicon lottery for ya I guess.

You wanted overclock results of our 8700k. I just found out after long weekend of stress testing that I can run my 8700k at Vcore 1.34v relatively stable. Means I passed 8 hours of Prime95 v26.6 in blend and 8 hours stress testing in real bench.

Interesting enough, Real Bench (which uses AVX) passed with all vcores starting a 1.31V. But prime 26.6 blend mode had blue screens within 8hrs with Vcores under 1.34v.

What kind of stress testing did you do? 1.28V seems a little low for stable it used with AVX. I can totally see you reaching this stable with no AVX but if you run heavy AVX workload benchmarks stable for longer than 8 hours at that voltage you would have a real good chip.
