Safe Voltages/Crashing?

I was overclocking my i7 4790k again last night and i gave it plenty of headroom (1.350+V) and i only went to 4.8, my temps were fine never above 60 throughout a benchmark but i kept getting bad crashes (not even BSODs just freezes where my quick reset button wouldn't always work, do I need MORE voltage?? 1.35V is already alot and I don't want to heavily damage it.

4.8 is a stupid high overclock. only the luckiest chips get to that. drop it down to 4.5, still plenty fast enough

I don't keep it at 4.8 all the time only for when I really need it or for benchmarks, still wondering about the crashes

I run my i7-4790k at 4.6GHz and 1.2 volts. I can safely run 4.8 GHz at 1.25 volts. You should try that.

4.8 usually can be done by most chips from what I've seen, they just need a bunch of voltage to get there, I wouldn't really call it a "stuipid high overclock"

Have you changed VCCIN at all in your BIOS? Bump it up to 1.95v from the  stock 1.8v, and see if that fixes it. (Your temps will go up further, but should still be OK)

Every chip is different, if it's already crashing he either needs more voltage for VCCIN, or more Vcore voltage.

Last time I did that I crashed my PC.. BAD like it bluescreened then it immediately lost signal to the monitor, regained signal, and continued this bad loop

Is VCCIN the inital Voltage? (thats what my ASUS MoBo labels it as i think)

There should be initial and eventual.

 

Initial is what you will boot at, eventual is what it will be once you boot.  Set initial to like 1.9v and eventual to 1.95v.

 

It should be called VCCIN or VRIN or CPU Input voltage

 

 

Take a picture if you can and post it here, that will help more.

Is that a bit overkill or is it safe, I mean, messing up my CPU would give me a great excuse for getting Skylake but I really would rather not haha

Plenty safe, and even if you kill your CPU, intel has great RMA service.  @ProKoN has killed like 10 4790k's and they always replace them, even without the tuning plan.

 

 

Your limits for VCCIN are closer to like 2.2-2.3v on watercooling, 2.6-2.7v on Ln2.
