I7 8700K Overclock

[Seba_XD]

Hello! I'm planning on overclocking my 8700K and I was thinking on 4.8Ghz. I know that all chip are different but I would like to try if my chip can do 4.8
This is my first time overclocking so I dont know lots of thing, from what I know I have to go to the BIOS and put the multiplier on 48 and voltage on auto, and thats it.
Some people told me to disable EIST and C-STATE, can you tell me if I should disable them and what are those things for?
If it really gets hot. should I put AVX Ratio to -3? I heard that AVX instructions are the worst for the cpu, they need lots of pówer and that makes de cpu run hotter than normaly.
I have an MSI Z370 Gaming Pro Carbon AC motherboard
Sorry for my English!
Thanks!

Let's start with the basics first. Do you have good cooling for your cpu and case? What's your power supply?

I have a Corsair H110i 280mm cooler and a Seasonic 750W 80+ Gold power supply
For the case I have a Cougar Panzer-S

You can likely reach your objective.
First of all, thei7-8700K is a beast at stock and really does not need overclocking.
How well you can oc is determined by your luck in getting a good chip.
as of 12/01/2017
What % of I7-8700k chips can oc
at a aggressive vcore near 1.4 or so and delidded
4.9 99%
5.0 72%
5.1 43%
5.2 16%
5.3 3%

I have a simpleminded approach to overclocking.
Just raise the multiplier gradually and leave the voltages on auto.
You will not do as well as a true expert fiddling with all the other bios settings.
Monitor your temperatures,; monitor your vcore with cpu-z. 1.4v is the danger point.
Stress test to assess stability.
There are many stress testers out there, and none of them will accurately simulate YOUR workload
Many will use AVX instructions to generate heat, but such instructions are unusual in user apps.
The AVX offset will reduce the multiplier when such instructions are present.
Probably better to use a tester without heavy avx use. I think an older version of prime95(26.6) is good as is asus realbench.

I also advocate implementing speedstep and adaptive voltage.
That will reduce the multiplier and associated vcore when the cpu has little to do.
