What setting to overclock?

[Lunarstrike]

I am not sure what setting to overclock.

All I've down was do a cpu ratio of 45 to all cores but I need help with every other setting since I don't know anything

MY CPU COOLER (cryorig h7 tower)

Can someone help me with what to change Im also confused with avx

You might want to get yourself Prime95, HWInfo, and whatever monitoring/stressing tool you want. Install all those software first before overclocking. Run a baseline stress test and check how the temps and stability is. With that info, set core ratio accordingly. Increase the cpu voltage very slightly. If the PC fails to boots, or crashes after booting up (BSOD), increase the voltage or decrease the core ratio. Always keep an eye out for the temps and voltages. I wouldn't go above 1.41v for a 24/7 build or 85C for temps. I won't touch avx if you do not know what it does. It's an offset that will help with some stability. If you really want to try playing around with it, drop it to -1 or -2. Good luck.

You might...

This guy has the right Idea but I feel you may be a bit confused so Ill explain the difference between older over clocking and newer over clocking since I own both systems (AM3 Phenom II and AM4 Ryzen 1600X).

 

You see, the older, plain screen BIOS you used to see on your old PC had far less tweaking settings available for overclocking, meaning that over clocking was limited back then (Intel Core 2/ First Gen i3/5/7 era). Take my AM3 board for example. I too am restricted to only changing my CPU multiplier if I want to over clock, and my Phenom II X4 970 can only reach a maximum speed of 4.0 GHz stable (doesnt crash when running Intel Burn Test V2.54).

 

This limitation is due to the fact that I have no voltage control available for the CPU. If I had manual voltage control, I may have be able to push this CPU to 4.2 GHz or even beyond, but alas it is not possible. Some older boards do have voltage control but back in the Phenom II days your options were very limited and you would need to purchase a very high-end, expensive board to be able to do so.

 

Now days, much less expensive boards are available with far more options, so I congratulate you on choosing the right time to upgrade :).

 

By manually force-feeding your CPU a higher voltage, CPUs can now reach much higher clocks than people ever thought was even scientifically possible. This does however come at the cost of increased heat, noise, and less longevity of the CPU. Much more advanced options allow you to even overclock each individual core to your liking on most higher end boards (which you have).

 

The 8600K is Intels first i5 featuring 6 cores and it is a toasty little devil. It is notorious for running quite warm even at stock speeds, so be sure to follow his instructions ^ about stress testing the CPU at factory settings before you even THINK about over clocking it. The Cryorig H7 is a very good air cooler but there are far more powerful air coolers out there, so dont expect to see stable maximum over clocks on this cooler, especially considering the i5-8600Ks naturally high temperature and your small form factor case limiting airflow.

 

Since you are new to Voltage over clocking, I would suggest starting off a bit easier/lower on your CPU than what he ^ is suggesting. Set your voltage to 1.35 - 1.375 (or 1.38 for a less precise motherboard) and raise your clock speed by 0.1 or 0.05 GHz increments until you experience stability issues. Do not worry, the crashes will not harm your CPU :), only extreme over volting and extreme heat can do that. 85C at full loads is also just a tad too high of a suggestion for a beginner. You want the maximum life out of your CPU, right? So do your best to keep core temps at or below more like 80C.

 

Hope this helps, you can also just Google or YouTube search "8600K Overclocking". Visual aid is a big bonus for a beginner.

 

EDIT: Higher Voltage and Heat are the #1 causes of CPU failure, so take it easy and try not to cook your new, shiny 8600K!

 

Also, BIOS updates can sometimes help enable further overclocking or even help to provide a more efficient, cooler running CPU. Note that BIOS flashing can be risky if your board doesn't come with a secondary BIOS chip. If you only have a single BIOS and your computer freezes or powers off during the flash, your motherboard will more than likely be permanently hard-bricked and not fixable.

 

Good luck and have fun! You should post your results here and let us know how you are doing.
