What voltage for I7 7700K Stock speed?

[The Don Firas]

I have the i7 7700K stock speed runing 4.5ghz, 1.200V, 71 C in prime 95 v29.4 with small FFTs.
i get 40 C on gaming.
What voltage should i change it to so it can run with a lower temperature and stable
my cpu cooler is Arctic freezer 360

Well just like how all chips behave differently when increasing the voltage to sustain overclocks, all chips also behave differently in how much below stock voltage you can go before the stock clock becomes unstable.

Just decrease it incrementally and do the same stresstesting approach as you would when overclocking. Repeat until failure, where you dial the voltage back up a step and try a longer stresstest until it's long term stable.

 

That being said, why would you want to undervolt your CPU when you're on a 360 radiator with safe thermals?

so that voltage is safe and stable for stock speed ?

and what voltage should i put to run the cpu on 5ghz stable ?

check some overclocking guides (google "kaby lake overclocking guide" you'll get plenty of hits) as for hitting 5ghz, you may not be able to, silicon lottery plays a pretty big part in it. you might only be able to get 4.7 depending on the voltage it requires (1.45v max "safe") or the temperatures your cooler can manage (shouldn't exceed 80c on a regular basis)

The stock voltage is always safe and stable for the stock clock. If not, then you should ask for a replacement (though that's probably never the case).

For overclocking, I can only suggest you do some reading on it as you seem new to it.

Here are some links to CPU voltage, and recommended temperature:

thanks bro i appreciate your help
