CPU Overclock Safe?

[T_H_O_M_06]

I am kinda new to overclocking and I just got a new computer so I wanted to overclock it just to see how it would work and the performance gain.
The only thing is I don't know if it is safe. I've read intel cpu can go up to 1.3v max and I am at 1.296v.

My specs are:
-Intel i5-7600k
-Be quiet! dark rock tf 220W
-Aorus z270x gaming k7
-EVGA supernova G3 750W
-2 case fans

if that's stressed temperatures, you are fine

[Lurick]

So long as you aren't overheating the CPU, the voltage can in theory go as high as you want. I'm not saying crank it up but so long as the temps are under 80C or so when the CPU is at 100% load then you're safe.

[T_H_O_M_06]

Ok yes this is in stressed temperature

I've tweaked a bit and now i'm at 4.8ghz and 1.2v
 
Is this better?

that's not true. there are safe voltages based on the silicon. you normally look at overclocking guides and they will tell the safe range of voltages for that architecture.

If you can keep things cold enough, you can go pretty high, but I worded it wrong and there are silicon limits, yes. I'm talking about LN2 cooling and whatnot where you get crazy high voltages.

The lower the voltage the better, so long as it's still stable, you're good

id say they are probably better off looking up an overclocking guide and follow those guidelines for voltage.

Ok and sorry if I am kinda noob but now it is at 5ghz and 1.3v

and 67c on stress test

is it stable? that seems quite low for 4.8

I wouldn't push it beyond that.

If you can get it stable at 5GHz and 1.3v, then that's pretty good in my opinion.

Thank you!

It seems like the voltage is at 1.25v but it is set to 1.3v?

have you done stress testing? what program are you using to test stability?

I am using Aida64 for 8min

I think I will set it at 4.8ghz and 1.2v becuase at 5ghz XMP got disabled

you want to use prime95 as Aida64 doesn't really test stability as much as it tests temperatures.

also 8 minutes is not enough to test stability and you will likely get much different result if you run it for longer.

I will test it for about 2hours tomorow

yeah that sounds like a good idea 

[T_H_O_M_06]

Thanks everyone for the help!

I have done all my stress test, My cpu is now at 4.8ghz stable and 1.15v at 60C the only thing is Intelspeed Step is enable and when the cpu is at idle the voltage goes to 1.35v and when it become under load the voltage goes down to 1.15v. Is this normal or should I be worried?
