hello every body

i would like to overclock my 8600 to 4.7 / 4.8 ghz with my Asus strif F z370 and i've got bequiet dark rock pro 4


I will tell you if there are parameters to adjust in the bios and if my temperatures are correct
I made a word file with the parameters I modified.

if you have any suggestions or remarks I am open to any information or explanation


thank you

I can tell you straight away that your core voltage is a bit going to be pretty high. I have the same setup and only 2 cores ever break over the 77'c mark when the cpu is being stressed

this result provide occt test 15 mn
should I decend the tension CPU core voltage override at 1.26 V?

Can you help me ? FreedomEclipse if possible to give me your specs Bios configuration for 4.8Ghz

I normally play around with cpu offset in the bios. You want it to hit below 1.30v in the bios when the cpu is stressed. The lower the voltage. The better. I get 1.28v and my temps are 72'c during stress with 2 cores occasionally hitting 77 or 78'c for less than a second.

I also have a case with good airflow and use noctua thermal paste so that probably helps a fair bit with my temps.

Here are my settings. They might not work for you.

Id say they are within margin of error based on how good your case airflow is. All i can see is that you have one chassis fan.

If youre happy with 4.8Ghz then its time to tweak it by rolling back the voltage till the OC becomes unstable then push the voltage back up a tiny bit

Run prime95 for 2hrs or Asus Realbench stress test for 2hrs. then game on it and see how it goes. Because Prime95 uses AVX instructions - you might see your 8600k hotter than usual. People tend to run a negative offset for AVX but i havent had a problem with my OC.

stress test for a few hours, then play some games for a few hours - keep an eye on your voltage and temperatures with Coretemp, HWinfo or Rivatuner Statistics Server along side afterburner and you should be ok.

sometimes overclocks can pass all these stress tests for 4-6hrs (even 8-12hrs) and still crash when playing a game. You just need to keep tweaking your OC to find a sweet spot.

That's still a little toasty imo. Are you using the same voltage settings as me?

It's hot but it doesn't necessarily need to be colder, its still a safe temperature.

I do agree though: what we need to know is the voltages.

@Johnt31 can you screenshot from the top of HWMonitor when you are running the system under load with Prime95 or other stress test.
In particular, a screen shot showing CPU VCORE and some other stuff such as VCCST, DRAM, VCCIO would be helpful so we know what your voltages are when the system is being stressed.

Temperatures and voltages looks exactly how I would expect, no issues. If you are stable, its fine. You could try reducing core voltage another increment. Time will tell if you start getting BSODs.

Just keep dropping the voltage an increment or two at a time until its unstable, than bump it back up two increments and if it seems stable run it for awhile with your typical usage for a week and see if it crashes, if it crashes bump the voltage up another increment.

actually i'lm testing 1.280 v my offset is at + 0.230 =1.280v for 4.8ghz
at 0.220=1.264v occt tell me error about 10 mn but asus real bench test passed
