i9-9900K Overclock

Main question.
Do I have a bad processor?

So I have tried multiple times to try and get my CPU to overclock to 5Ghz, which is apparently meant to be very possible with the 9900K.

I have a Corsair H115 AIO cooler, and ASUS Maximus XI Hero Wifi motherboard.

What settings should I be trying and voltage to get the CPU stable at 5GHz?

I have used multiple guides, but can't hit 5GHz.

I am thinking it is my processor.

I ended up following the settings from this guy:-

However I only managed to get 5GHz using a 500mhz AVX offset @1.32V.
My temps also reached the high 80s.

I know the 9900K runs hot, but these seemed very hot to me, personally I don't like the H115 cooler anyway as the fans are pretty audible and very tempted to switch back to air cooling and purchase the Noctau Black Chroma.

Corsair Vengence 3200 - TBH I just have a DUD of a processor.
It is the only CPU I have owned where I have not managed to get any stability going on.

I just lost the silicon lottery, it doesn't matter too much as the performance of the CPU at stock is good enough.
I overclock for the love of it more than the performance gain.

Yeah, I am not going to..

At what overclock speed across all cores are you getting better performance than out the box?
This was just from testing again over the weekend with a new BIOS, hopefully I will be able to push the system further or with less voltage when I have more time.
