Sorry for the spam but I'm just making sure I am in the safe limits.

Is 1.425 V safe for 7600k?. I am trying to get 4.9Ghz stable

If you have good cooling, and the system runs.  Go for it.  when it becomes unstable, then back it down

So it's safe no chance of damaging the CPU?. I know it's lifespan will be increased but y'know

Only if you can suppress the temperature on or below 65C

Their is always a chance of Damage to the CPU, you have to be careful. I am going to Ramp up mine when I finish the water cooling.

Uh fuck no. Max safe voltage on kabylake is supposed to be 1.4v

Temp vs operational stability

 

The line is where you want to go.  Some people have serious overlocks, but with liquid cooling they keep that temp way down.  Some even have Chillers units on them.  So if your using air cool, Liquid cool.  All depends where you feel safe in pushing the CPU.  

 

Just found this:

 

So I got my I5 7600K to be OC stable at 4.6ghz - 1.28vcore. However, going above that requires quite the voltage boost. Right now I have 4.8ghz at 1.38V stable via OCCT Large Data Set.

You shouldnt need even 1.4v unless you have a bad chip to get 4.9. 

 

An average from a bunch of overclock.net users is 5.0ghz @ 1.36v

So 1.45V is okay? People are telling me different things. AWW!!!

Are you sure you aren't mixing up voltage (v) and frequency (GHz)? 1.4v is the most you'll need and there really isn't a limit to frequency.

I wouldnt want to go up to 1.45v but if you like to live dangerously and you have good cooling you'd probably be okay.  Not any further for sure. If you still can't get 4.9-5.0 on 1.45v something is wrong or you have a shit chip

I'm not getting mixed up.

I am running at 1.45 V is that okay??

Have you tried lowering the voltage? Just because you CAN use 1.45v doesn't mean it actually needs it.

I have tried, wasn't stable on prime 95

Hmm. What about at lower frequencies? Some chips hit a "wall" where it requires way more voltage to raise the frequency even a little bit.

Yes I could run 4.7ghz fine at 1.375 I think

It's good if I get 60c on 1.45?

If that's after 1-2hrs and 60c max yes

Could all this be happening due to a faulty PSU? I have heard some funny noises from it recently

To me thats a bit warm.  Air Cool or Liquid Cool.  If Air I would bring it down a little.  If Liquid, something wrong with liquid cooling.

Yes it might not be delivering stable voltage in the first place. 

 

If you have your memory overclocked put that on hold for now
