Too much voltage?

[VirusStorm]

I am currently testing the stability of my i7 6800k @4.5ghz on prime95. But my voltage is at 1.435v. I know this is lower than other people needed for the 6800k, but is it safe? Is it recommended? My temps are fine, but will it be okay to use my cpu at this voltage?

Too high imo

The voltage is still high, it's a combination of the two which you need to balance since your still pushing over 1.4V into the CPU. You really shouldn't go over 1.4V, if your watercooling and have good temps a good recommended voltage is 1.35V.

What are the cons of a high voltage?

the problem is that voltage kills cpus, not temperature,

i can try to get it down to 1.425. would that work?

if you use adaptive mode it should be fine

With that high of a voltage you risk very early degradation of your CPU. What temps are you getting when your stress test the CPU, at that voltage most watercooling solution won't be very effective. And drop to voltage down to 1.35V MAX if you are planning this as a daily driver.

30-40c idle

60-70c load (prime95)

as stated above, you shouldn't be concerned with temps unless they are too high. Voltage is important, don't blow it off. 

[cj09beira]

as long as you use adaptive voltage so that it scales with core frequency it shouldn't be too bad

Are you stress all core small FFT and FPU and cache? 

 

Even though those are good temps you are still pushing it really hard at 1.425V.

btw i am at 1.4 with my 4690K with adaptive voltage, how i am ?

I still don't recommend it, especially with something like the 6800K which I assume will be used for heavy workloads like rendering hours on end. That will peak it at the max voltage for that duration.

Depends on temps and overclock but that's still ok, I don't usually recommend going more than 1.35V for daily use.

good point, OP what do you use the pc for ?

I was able to get my 6800k to 4.4ghz @1.35v stable! Thanks for all of your help guys!

Just over 1.45v is more than fine for encoding type workloads with Broadwell-E.  Obviously as you start doing more number crunching stuff or running Prime95 w/ AVX all the time just to say you can do it, you'll need to drop voltage and clockspeed to remain relatively safe.  

 

Research more and listen to opinion, to include those of my own, less.  Too many theories out there.  The more you inform yourself, the more comfortable you'll be with the overclock choices you make.  I think you'll find that people are either way too conservative with advise or just flat out making shit up as they go.  Hell, even I do it.   

 

Good read provide by Raja over at Asus.  Basically all the stats and information you'll need to know about Broadwell-E.

Good luck man.

Thanks so much! If I get it to 1.45v I will definitely have it stable at 4.5ghz...maybe even 4.6ghz! Is it safe though?

Read up my friend.  Like I said, formulate your own opinion.  Voltages for HWE and BWE are essentially the same.  

 

Is it safe?  Completely subjective bud, but I think if you look around enough, you'll find that answer very easily.  When searching for answers specific to a platform, stick with threads dedicated to that platform.

 

There's more information in the BWE thread that I've linked than you'll care to know.  Combine that with the write up from Raja@Asus and your are set!  Asus literally tests thousands of chips right before and after each chip family launches.  They break it down nicely.  Statistics and everything included.  This is where you start to learn that some people's claims are just too good to be true.
