4770K 4.7ghz question

[Wherestheanykey]

Hey all just been doing some overclocking on my 4770k so far im @ 4.7ghz i needed to use 1.4v to get there but been stable for over 5 hours using Aida64

with temps hovering around 70 degrees (will be testing for longer)

 

I been doing so much reading on ocing these cpu's and every different page i go on it says something different

for example some say don't go past 1.3!!! and some say 1.45 is max...?

 

So my question is... will my cpu be ok at 1.4v aslong as the temps stay at 70 degrees? 

fyi i have tried lowering volts down but 1.4 seems to be the sweet spot @ 4.7 for my cpu 

 

pc specs are in sig if your wondering

Well your temps are not an issue in the slightest, but when overclocking you do know that your are shortening the lifespan of your chip. Every chip lasts for a different amount of time at different voltages, although I don't think 1.4 is all that dangerous, so you should be fine

If you are getting temps that great, I say go for it.

 

It will reduce the lifespan of the chip but since you are overclocking, I would wager that you will upgrade before that actually matters and if the chip dies, it just gives you and excuse to upgrade

Yeah I'm not overly fazed with reducing the lifespan i obviously don't want to fry it but if people say the temps are good and that 1.4volts isn't too high then i will continue with stress testing and hopefully get a 24 hour stable oc or may even try for higher i guess as long as the temps stay below 85-90?

85-90 are fairly high temps. I always try to aim for 70-75 max.

ok maybe i should just be happy @ 4.7 then....so many people say different things from what i been reading anything in the 80's is ok but i guess thats the internet for you.

how can you hold 70c with 1.4v under full load on a 4770K ?! this is an insanely hot chip what cooling solution are you using? nitrogen?

1.4v will reduce the lifespan of your chip if you plan on using it a couple years you should consider 1.3v or bellow.

Yea, it's like you say. Every person will say something else. It's better to set a max temp for yourself, a temp that you feel comfortable with after reading all the stuffs. 

 

I got 1 Q though, 1.4v for 4.7ghz? What's the standard V on that cpu? I (personally) think that 1.4 is kinda high lol. (I'm running at 4.2@1.255v myself)

1.4v will significantly reduce the lifetime of you chip if you plan on using it a couple years you should stick to 1.3v or bellow.

I've benched at 1.38v on my 4790k at 4.9 ghz on a 212 evo and only hit like 82 when stress testing, I'm sure his h110 does 12 degrees better than a measly 212 evo

He probably got one without horrible TIM

TIM...the 4790K has nice tim the 4770K don't...maybe he delided...mine is horrible my 212 can't even dissipate 1.25v...luckyli though my cpu can do 4.3ghz at 1.19v

Using Corsair H110 in Corsair 750d case

i thought 1.4 was very high aswell but i figured the temps where pretty good so couldn't be that bad but i agree 1.4 is up there

Not delided btw

if you have an adaptative voltage overclock 1.4v is still not bad if your temps are way good.

The CPU should hit 1.4v only under load so the rest of idling time is fine...i'd go with 1.35v for 24/7 use though.

Some 4770k don't have Tim issues some do, its kind of a hit and miss thing from my experience

So in the end i stress tested for over 12 hours with no dramas with temps staying the same and no cpu throttling so stopped test and opened BF4......and bluescreen so wasn't as stable as Aida64 was showing not sure if it will never be stable or if i need to change a few things for it to be ok but will be playing with it further soon. 

 

any suggestions on things to change to help with stability?

yes, follow this overclocking guide carefully:
