Okay so i finally got my pc working and got my new cooler in (H115I PRO) and getting very good temps.

I know you can 'boost' it i think but im not great at all with the bios. Is there anyway I can do it through a software? Really don't want to break it/ get damaged. Got a rog strix z370 motherboard.

Thanks :)

Looking at your post history and considering your lack of basic computer knowledge ( no offense but true ) the last thing you need to do is attempt to overclock anything.

No program that will do it then ? No way am I going near the bios

Hi, overclocking CPU with softwares is just asking for trouble, especially with instability. There are lots of auto-overclocking programs that will do it and mess up half your bios while doing it. There are also manual ones that require complete overclocking knowledge.

Now back to the topic, just go to bios, Ai Tweaker, CPU Core ratio> Sync All Cores > Enter your overclock to the "1-core ratio limit" (45 or 46 or whatever you like). 45 = 4.5Ghz, your clock is 3.7Ghz
A pic to help you: https://www.idgcdn.com.au/dimg/1200x1200/dimg/strix-bios.jpg

Stress test with prime95 or AIDA64 or game hard for 30 mins, check your average temps, if they are below 85c, your good to go. If not, lower your overclock to 43 or 44.

You can revert your overclock by resetting your bios, a two button step done easily from bios.

BTW, why won't you go to the bios, it's pretty hard to damage new systems with overclock, unless you mess around with your bios (like applying 1.5+ voltage) or try to damage it for test purposes.

as the guy said above i probably shouldn't. I know how to build pc's but thats it :) Never wanted to and still don't touch the bios. Can i do the boost thing though? Or is that an option on my cpu. Is there any video on it too?

Boost (GPU)-Turbo (CPU) is enabled automatically, you don't need to touch anything.

You can use Intel Extreme Tuning Utility to overclock your i7 8700k. I used it successfully for two weeks to overclock my i7 8700k on my AORUS z370 Gaming 7 (similar to yours) and it worked with core multiplier 47-48 [4.7-4.8ghz] on all 6 cores (cache/uncore set to 200-300mhz less) with default voltage (and default everything else) for two weeks, until it started becoming unstable for some reason. I eventually resorted to the BIOS, and it's more stable, and should still work with default voltages. I think the STRIX has "presets" for overclocking in there too.

Make sure to save BIOS profiles so you can go back if it becomes problematic, but as long as you don't push it too far and do things you haven't properly researched, you'll be fine. This processor has really good safety features, too, and should be protected so long as you don't override it's default safety features and over-voltage it (for example, 1.4V+ is bad your it's health/longevity) If you just want something simple like a 4.7-4.8ghz 6 core overclock, it should be perfectly safe with default voltages, and temps should be good with AIO and even okay with air cooling, doing it either from the BIOS or the IXTU I mentioned. If you're going further (which may not be necessary to you), you should definitely put in more research and look into details. There are guides online for how to do this, BUT each processor overclocks differently, so your mileage will vary, so be wary.

Edit: You may have noticed that the processor clocks at 4.3ghz on all six cores by default, so 4.7-4.8ghz on all cores isn't something to sneeze at. There's also the factor of the "silicon lottery" and for all I know, you processor might be great for 5.3ghz overclocking, but it also might not be able to get past 4.9ghz. If you're willing to risk it and do the research, you could find out, but you don't seem like the type and you don't need to be C:

Would there be any video by any chance? Just really have 0 idea on what im doing and dont know what volts does :) I do video editing and gaming so what ever is good to do with that please let me know !

Are you OK breaking your new build? Dealing with returns ( and getting denied since you broke it ) sound like fun? Then find a youtube video by all means.

Or recognize that overclocking is for enthusiasts and either forget about it ( it's not necessary anymore anyway ) or start learning what you are actually doing.

Like I said above, looking at your post history you have no business overclocking anything when you can't copy/paste yet.

Just because you CAN do something doesn't mean you SHOULD do something.

Just to make sure, What rig do you have and why do you want to overclock?

Are you OK breaking your new build?
It should be pretty hard to break it with mild OC unless he does some stupid thing like unlocking extreme voltage lock.

But he's right though, with all the BSOD/freezes/crashes/pc not turning on/etc, OCing CPU is not for the faint of heart. Unless you know some technical stuff.

Well, literally what I said. Otherwise, videos shouldn't be hard to find... if you really don't know what you're doing and you don't feel comfortable doing it, you don't have to overclock to get great performance out of the i7 8700k. Every individual processor overclocks differently so you can't necessarily just use somebody else's settings. Overclock with caution, it could damage your processor.
Run the benchmarking tab before and after changing settings in IXTU and save profiles with it before and after making changes, so you can easily revert back if you encounter problems. Always have a temperature monitoring program active too if you decide to overclock.

Installing the Intel Extreme Tuning Utility and under manual tuning settings, set the core multiplier from 47, 46, 45, 44, and 43 on each of the six cores to x47, which brings the clock to 4.7 ghz and should work well with default settings everywhere else, and would be considered an overclock. x48 multiplier might be fine with your specific processor and cooling with default everything else, too, but you shouldn't increase the "cache" or "uncore" frequency above x45 even with 4.8ghz core, and should leave it at default with 4.7ghz core.

Not that your CPU might run a lot hotter with such overclocking, and the benchmarking tab should give you a decent indication of by how much... however, with water's high specific heat capacity, it may not render the higher temperatures in the course of the benchmark, so again, monitor your temperatures always, or else you'll have a $350 hole in your pocket. With an AIO liquid cooler, temps should be okay, but don't count on it.

Rule of thumb, if you don't know what something is, don't touch it. By default Intel has security features and you could disable them and ruin the CPU if you don't know what you're doing. Honestly, especially for 4.7ghz and maybe even 4.8ghz [depending], all you might need to even touch is the core multiplier - this is in either the BIOS or IXTU. Going beyond my suggestions, if you can't figure it out on your own, it's probably best to stay away from anything more advanced. :)
Hope that clears everything up.
