is 1.328v to much voltage to give a i7 4790k for evreyday use ? will that much voltage degrade my cpu fast ?

I recently delidid my i7 4790k using coollaboratory liquid pro in between the die and the hs so my temperatures are very good @ 4.7ghz I use 1.255v typed in my bios and 1.28v in cpu-z under full load and my temp is 66c . and @ 4.8ghz I use 1.295v in my bios and 1.328v in cpu-z under full load and my max temp is 69c . is it safe to keep my i7 4790k @ 4.8ghz using 1.295v in my bios and 1.328v under full load in cpu-z ? or will my i7 4790k degrade quickly ? and is the i7 4790k able to take more voltage then a i7 4770k with out degrading ?

I ran occt for 10 hours @ 4.7ghz and 8 hours @ 4.8ghz and I monitored my temps with real temp 3.70

wow .. cool .... that is a very low temp
mine is at 4.5 and OCCT 6 hours 1.181... max temp is at 81c
i'm use NH-D14 cooler

might need to try coollaboratory liquid pro hehehehehe

btw. my ambient temp is 30c

do you have a i7 4790k ?

wow 81c is hot and you are only using 1.181v under full load in cpu-z . 81c is how hot my i7 4790k was @ 4.7ghz using 1255v in my bios and 1.28v under full load in cpu-z before I delidid it . my cooler is a corsair h100i which is about the same or a little better then NH-D14 when it comes to cooling . if you ever decide to delid your i7 4790k make sure you use coollaboratory liquid pro in between the die and the hs . regular thermal paste in between the die and the hs wont improve your temperatures that much . I tried gelid gc extreme which is a good thermal paste and my temps only went down maybe 3 or 4c . when I applied coollaboratory liquid pro my temps dropped a lot

I'm kind of afraid to delid .... seen very good result from peoples .... I'm not hard cord gamer or OC.
like to OC little and have fun with it .. 1 way to learn about the MB and the chip. don't want to mess too much.

I'm sure every day use I won't ever hit 75c. but like to keep mine OC to be under 80c max in stress test.
the hottest on all the stress test is IBT at 86c. want to keep the chip at least 5,6 years.

1.4 is very very high voltage

my idle temp is in the high twenties low thirties . what kind of cooler do you have ?

It's absolutely unimportant what cooler he has when his voltage is on 1.4v. Even if his temps were under 40c under 100% load, the chip would still degrade so fast you could almost watch it.

which is better Pro or Ultra ??? (people said Ultra is easier to use and they both about the same)
just hate my temp ... debate on delid now ... hehehe

the pro performs better then the ultra . it was pretty easy for me to apply the pro . all you need is a tiny drop and it spreads around pretty easy . just be carful not to get it on your cpu socket pins

Not really, not with a good cooler, 1.4 volts is about the limit for what a NH-D14 can cool. If the paste is applied properly and their is adequate torque applied(don't torque it too much please), a NH-D14 can sustain a 75 degree upper limit in prime 95. Since I like my CPU to be 70 or less in a worst case scenerio, I like to keep the voltage under 1.35v.

If you see the temps stabilize, but slowly climb afterwards, heat is accumulating inside your case, check your case cooling.

The Auto voltage will fry your CPU alive if you try overclocking with it on, it by default was giving my cpu 1.8v... Talk about a total wtf moment. This is on a Asus Hero VII. VRM temps stablize at 59C at 1.35v in my case.

An average 4790k can be stable at 4.6Ghz at a 1.35v, you can do better than that if you win the silicon lottery.

In my case, I ran prime95 overnight(8 hours) and was still running like a champ, so that is stable enough for me.

It's not about temperatures, it's about electromigration. Have fun with cutting your cpu's lifetime span by 2.
I can run my i7 4790k IBT stable with 1.31v (possibly a bit lower) on 4.8ghz or with 1.27v on 4.7ghz. Yet I stay at 4.6ghz with 1.22v, as I hit up to 81c on 4.8ghz and still go into high 70's with 4.7ghz. I would still keep things down, even if I were able to cool it down to 65c. I plan on using this cpu for about 6-8 years, and putting it under high voltage could not go well with that. Generally, 1.3v is considered a safe range for long term use.

what kind of cooler do you have and what stress test are you running ?

you might be able to reduce that 4.6Ghz voltage even more, maybe to 1.15? (to keep the temps under 60 possibly and maybe below 50 when gaming)1 considering im running 4.7Ghz @1.21V (Stable with intel XTU).

No way, 1.15 is what I need on 4.4ghz.
I would consider myself lucky, only needing 1.27v for 4.7ghz. But 1.21? Man, you probably got the 'best' chip out of all 4790k's. Usual voltage for 4.7ghz is 1.3-1.4v, which is where most chips limit.

My temps are below 55 while gaming, by the way, which is nothing I worry about. I'm just also often rendering while gaming, which is why I like to stay below 70c in prime 26.6.

Actually, if you only need 1.21v for 4.7ghz, the first thing I'd do with your chip is shooting roght for 5.0ghz with about 1.3v. And possibly even higher.

Guys, I just OC my 4790k. She is doing fine 4.9Ghz on 1.29 V. Intel burn test and aida64 no problem. Cooling H110 hits max peaks 85C on stress loads. Is it safe to keep this setup, or should I go down to very safe 4.6Gz at 1.15V which is super cold and healthy..? I mostly use it for games. Thank you.
