post #7441 of 33547
What do you guys think about voltage vs. temps in terms of safe levels for your chips? I know it's been discussed many times what the maximum safe voltage is to have running through your chips especially for 24/7 use but I don't believe we've ever gotten a definitive answer from Intel. Do you consider running higher voltages unsafe even if your temps are really low?

For example at 4.8Ghz @ 1.35vcore (DMM reading) my temps in Prime never go above 53C. Even if I up my vcore up to 1.45v my temps never go above the 66-67C. I know many people have mentioned 1.52 as the ceiling for vcore even though it's unofficial but I get the feeling I wouldn't reach my temp limits until well over 1.55+v. So I guess my question is, does voltage matter less when your temps are really low or should voltage be observed the same regardless of temps?

i wasnt to happy with this answer, because others told me i was wrong with the 1.52V vcore max,
and VID has nothing to do with vcore...so i kept searching...
and another intel employee said,
yea i found it, look here and here, hope this helped bla bla, Warning: Spoiler! (Click to show)
so i looked, i was like ..wait wait , all kinds of voltages there, EXCEPT where the vcore is...LOL
and i have a email somewhere, another try to get a answer,
where they say, that they cant give me a clear answer about max vcore,
and i have posted on the official intel forums asking about it,
no answer or any respons yet smile.gif
so, im curious now , tel tell biggrin.gif
the solders, i did several searches to find it,
compared them, and got the between 30 and 60 w/mk,
you thinking im wrong?


I must be losing my memory in my rapidly approaching old age biggrin.gif That was the exact chart I was thinking of, but the OC guide Sin posted (iirc) stated 1.52 Vcore as Intel's recommended max. On second thought, I'd rather have official confirmation on that myself.


I'll post Sin's chart, because I don't remember where I found it off the top of my head, in a few hours. I'm giving my Prodigy a little longer in front of the space heater to be sure it's dried out from what I'll lovingly refer to henceforth as "The overflow incident" wink.gif Oh wait, as I was typing out the last line, I remembered.




Under the "Settings" spoiler: Sauce


With his connection to Giga, I'd imagine that's the proper specs provided by Intel. But an official answer would definitely ease everyone's mind.

Oh no, I don't think your wrong about the leadless solder, I'd just like to read up on it myself to pass the time. I just have a voracious appetite for information... tongue.gif

I think voltage is important no matter what...well maybe less if at -200 something. I would think all electronics have a limit of how much voltage it can take before its fries itself.

So in other words I'll just have to live with my chip being at very low temps all the time? I guess that's not such a bad thing thumb.gif.

lol yup. or think of it this way... what happens when you give a speaker too much power? It may sound great but at a certain point it seizes or blows the voice coil.

in terms of degradation, heat is worse then running higher vcore, within vcore specs,
heat shortens lifespan more, i made a post about it somewhere, with a cool graph,
and a link to research..over a 3 year period

any vcore above 1.52V is getting more risky, 1.55 is absolute max on air/water,
i think we should trust the people who know alot, like sin0822 and others elsewhere,
we tent to use their findings, research/reviews and answers as true, to help others, but its not "official" sometimes..

above 1.6V vcore 24/7, things get really risky, for benching its no problem, at least i think it isnt,
then temps dont matter anymore too, then the only thing is extreem coolling..

o, and we do have a max for temps, 105C tjmax, but not really for vcore,
but 1.52V max for 24/7 oc seems reasonable so far..1.45V max for 24/7 i would advice if asked, for safe..

I'm going to have a hard time telling myself 1.52v is unsafe for 24/7 use if my temps never go above 75C with Prime, especially since I upgrade once every 2 years. I'll have to see where I stand when I test it biggrin.gif.

On Air/Water: Intel Rec. Max is Intel’s absolute maximum rating for the Ivy Bridge lineup, many of the numbers provided are identical to those of Sandy Bridge, however ]while vcore should be lower because of a better processing technology (22nm vs 32nm) it is max 1.52v here because of the SVID max.When overclocking on air the only two voltages you should need to touch on an Ivy Bridge setup are the Vcore (which you increase) and the CPU PLL( which can be decreased to help temperatures).

if you read whats under the charts, youll see sin mention the same VID,
that i found in the datasheet from intel,
i used that same chart for a while when people asked me about max vcore,
then some peeps commented me on using 1.52V vcore as max vcore intel states,
"not true, intel doesnt state that anywhere, bs..bla etc"
so i started seaching, and found the chart in the datasheet,
then some others said, that VID has nothing to do with vcore ....LOL

"appetite for information"..yea, i know that .. biggrin.gif

So I just got back from microcenter. I purchased an Asrock extreme6 motherboard based on it having the improved mosfets. I was sooo close to getting the Asrock Z77 OC formula lol.. Such a waste of $$ on air though and probably even a waste on water. No idea when I will get it installed and running as two kids and a wife are the dictating factor in that one. I would need a full day almost to swap, install OS,updates, programs and games. But I feel a bit better now about running an overclock for a couple years. I will keep you posted. It was $149 and I used a $20 coupon from the 3770k for $229 thread, so after 3.5% tax it was $134.. Same price as the extreme4 lol. Now to sell the extreme4.
