9600k Overclock Question

So I spent the last few days tinkering around with my 9600k. I just want to know if I really REALLY lost the silicon lottery on this chip. 

 

4.9ghz | 1.284v | Turbo LLC | AVX offset 1 | Low 70c

 

BUT

 

5.0ghz | 1.354 | Turbo LLC | AVX offset 2 | High 70c

 

Am I doing something wrong here? Why does it require more so much to push it up to 5.0ghz? Temperatures are not an issue. Running a NH-D15s. Just confused why 4.9 runs so much more efficiently than 5.0ghz

 

Stressed on Prime95 26.6 and Prime95 current version for non-avx and avx stability.

because you're nearing the frequency limit of the CPU and power leakage starts to get serious.

any thoughts on safe voltage on 9th gens? I've heard 1.35 1.3 etc.

1.4v, if temperatures dont get to 80C because at that point temperatures drop you more stability than voltage can gain
