Overclocking settings for i5 8600k and MSI Z370-A Pro

[martin.carline]

Hey guys,

I've watched some vids online but struggling to completely understand everything. Was wondering if anyone has overclocked the i5 8600k using an MSI Z370-A Pro board (or something similar) and could share there overclocking settings - obviously only what they've changed and possibly why?

In the past I have only ever overclocked an i7 875k using an old P55 motherboard, and all I had to do was increase the multiplier and voltage, but I've noticed there are lots more settings on these new motherboards like the ATX instruction to not have the frequency running at full at the time etc...

Re Martin,
I post the same thing than in the other thread to let others Know that it's solved 😉

The first Goal of overclocking is to find the minimum voltage required for a given frequency
First, at stock, note your frequency and voltage you can read during stress test.
You put them in manual mode in your bios.
Then, you have two ways :

1°/ Better performance :
With stock voltage, bump your multiplier until it's not stable then bump voltage (increments of 0.025-0.05V) and so on.
Once you've reach the stable frequency you want, lower the voltage as much as you can as long as it remains stable.

2°/ Better thermals :
Keep stock frequency and reduce voltage as much as you can until it's not stable.

For 1°/ and 2°/, once you're done with your tweaking and that everything is stable for your usage, you can re-enable power saving features as C-States and put the voltage on adaptative to let the voltage and frequency fluactuate with the load.


Tips: stay below 1.38V and 85°C during stress test for daily usage.


I can give you my settings but it will be different on your setup.
CPU ratio :52
Avx offset:-2 (so your processor will be at 5GHz when AVX instructions kicks in)

CPU Voltage : adaptative + offset (carefull, it can overshoot so go easy on this)
This, combined with C States and EIST let the voltage fluctuate with the load

CPU Voltage : 1.385V
CPU Voltage offset : -0.015V
CPU SA Voltage : 1.18V
CPU IO Voltage : 1.17V
C states : enable (dectect the "state" of the CPU)
C1E : disable

EIST : enable
This, combined with C States and Adaptative voltage let the frequency fluctuate with the load

Turbo boost : disable

Thanks again. Thought I'd post it here in case anyone didn't answer - but yours is perfect
