Hey guys, I recently just bought and set-up my first ever PC Build and now I'm trying to learn to Overclock my CPU to it maximum potential, while still maintaining stability, as I'm sure everyone would be. I have never overclocked ever, so I was wondering if you guys can help(maybe even share your own i7-8700k OC set-up, so I can get an idea. I've been doing some research and I think I managed to Overclock my CPU, but will return to default once I receive some answers from more experienced Overclocker's and proceed from there. Thanks so much in advance!
Set-Up:
CPU: i7-8700k
Motherboard: Asus Prime Z370-a
CPU Voltage, CPU Bus Speed, ETC: https://valid.x86.fr/jayktj
Ram/Memory: G.Skill Ripjaws V Series 2666MHz 16GB (8x2)
Cooling: Masterair MA610P
OS: Windows 10 Pro

Curious as to why you want to overclock but you bought DDR 2666mhz instead of,3200mhz? Every CPU has a different limit. Best way is to start with a overclock profile in your bios then go to voltage and start with stock voltage and work your way up, no,higher than 1.4v. Start with the boost speed and work your way up.

Regardless of your end result you will likely not get any noticeable benefit,in games. I had fun overclocking my 7700k to 5.0 and now just run it at 4.2. FPS are the same at 4k and,my CPU runs much cooler.

I actually only bought 2666MHz ram for temporary use, although I should own 3200mhz of ram by next week. I initially planned to buy 3200mhz, but was a little short on budget. Anyways thanks for the info, but may I ask, what an increase in my voltage would do to help improve my Overclock, would I simultaniously be increasing my CPU Cores as well?

Hi jaysolo23,

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.



Rodolphe.

Okay, I finally was able to get back to tweaking with my CPU and I now have another possible issue. So when I set my core Voltage in my bios to 1.35V and my Core Clock to 5GHz, and boot it, CPU-Z, detects a Voltage jump and it goes from 1.328V to 1.344V, although this happens when I am using the CPU at 100% load, using CinebenchR15. Please help me understand why that is and if it is bad and if so, what would be the best Voltage for my CPU at 5GHz.
P.S - While under load, my CPU reaches a max temp of 79*C, under its current voltage setting. I have tried booting from a lower voltage and my computer still manages to load up, but again it over volts to 1.344V. I have turned off the turbo mode as well.

There is nothing wrong with the memory you've bought as a matter of fact I have 3200mhz that I run at 2666mhz.

Why?

Because the 8700K CPU was designed by Intel to run 2666mhz, so if you run the memory at your CPUs design specs the CPU runs cooler, and allows a higher multiplier overclock.

Your memory will run 2400mhz at timings of 15,15,15,35 at 1.20v DDR4 slot voltage.

http://www.tomshardware.com/forum/i...r-effect-raised-multiplier-cpu-overclock.html

So you just built your first machine and now since that seems easy you want to overclock?

You need to take your time and study up on how to BIOS overclock, that's taking full control of your overclock, learn first, then do it.

This link is old but still applies;

http://www.tomshardware.com/forum/id-2345618/reaching-cpu-overclocking-stability.html

Your overclock will be limited first by the cooling you are running as you have to keep the temperatures under control.

http://www.tomshardware.com/forum/id-2196038/air-cooling-water-cooling-things.html

Your next limitation is your overclocking knowledge, and that is up to you, you have pretty much unlimited resources just by Googling what you want to know.

Lastly you need to learn the CPUs limitations and how it is affected by temperature, meaning you need to know when you've gone too far for the cooling you have.

http://www.tomshardware.com/forum/id-1800828/intel-temperature-guide.html

I personally will not give you your BIOS overclock settings as I said that is up to you to learn, but, if you are trying to learn and do not understand something PM me and I'll explain what you don't understand, that way I can see your are at least trying to learn, and not waiting for a hand out.

Good Luck! Ryan

The 8700k memory controller is 2666mhz so idk why you would run your RAM at 2400mhz and bottleneck your system. I wouldn't recommend anyone else to do the same either. Memory speed is not a large factor for Intel but higher speed does have performance gains and 3200mhz is the best price/performance for RAM.

My bad, I had my 7700K on the brain, I corrected it in my post.

Thanks! :)
