8700k overclock

Hey guys, I want to try this CPU with different settings, going to see the best temps, and find a sweet spot for frequency and thermals.

Is enhanced turbo is something that needs to be off if I am doing 4.8-5.0 ghz?

Normal Turbo will be off, but for some odd reason Youtubers are saying to leave enhanced turbo on, why?
They are overclocking past 4.7, am I missing something?

Any other overclocking suggestions are appreciated. I already know to turn off Multi Core Enhancement, and to enable XMP to make ram what it's advertised.

Any other tricks with new chips, I don't know about?

I am coming from 4790k, AVX seems confusing. I kind of get it, but I also don't

Thank you, I already overclocked successfully, and reached 4.7 ghz stable on 1.21volts
After I delidded the cpu with liquid metal it's running 10 celcius cooler than my delidded i7 4790k.

8700k is an EXCELLENT chip! Max temp of 67 Celcius after delidding and running Aida64 for close to 3 hours, that's with Geminii S524 air cooler with Noctua fan on top. Who would have "thunk" that 8700k can be cooled with this cooler no problem. Even without delidding it was going up to 91 Celcius max, after delidding I don't even hit 70 Celcius.

Good times!

If you need help, let me know

Got a 8700K recently as well. I didn't do well on the lottery. Get to 4.7-4.8Ghz under after 1.4V. 4.9 takes 1.45V. With a Corsair H150i, on load I am in the 80s Celsius with 1.4V. I hit close to 100C with 1.45V. These chips like to run hot. This is with an ASUS Maximus XI Code. Looking back I should had got an i9-9900k and cheaper board.

Whoa, I would return that chip for an exchange. How long ago did you buy it?

Doesn't sound right. Above 1.4 there is definite degradation with 8700k, let alone 1.45

The chip is faulty, brother. Seriously.
You are still under warranty with Intel, you can RMA it for an exchange or go through retailer where you bought it, that's quicker than Intel.

Just from some initial searching it looks like the board is probably more to blame here. It seems like a lot of people need high voltage on that board. The variance in the chips are just unlikely to be that big of a difference from Intel's perspective.
