I am using h80i cooler

yea, that looks good to me, for example, i need about 1.3V vcore to make 4.7ghz run 24H prime stable.. temps look nice also smile.gif

temps have gone up to upper 70s 76-78c not over 80c on the normal no core has gone over 80c so 1.33v is good for 4.7? think its a chip worth delid?

also under prime95 my cpuz says that the min temps are all in the mid 60c (64-67c) isnt that bad? meaning on boot i am hitting 64c idle?

this smile.gif

it is true tho, that the max VID is considered to be the max vcore you should run a cpu 24/7, if temps permit of course smile.gif
but i wouldnt let my ivy run 1.52V vcore 24/7, i think the 1.3-1.45V max vcore range is safer for daily or 24/7 usage,
upto the user really, what he thinks is the highest vcore he can run his chip..


im thinking about this remark a ocn member made a while ago, when we talked about the max vcore for ivy,

"I know for prior generations, the maximum allowable VID from the factory was considered
the maximum voltage for the processor. Not that that max VID was ever really spotted in the wild
for consumer usage. LGA775 was max of 1.45V VID, and that was widely considered the maximum you
should operate in a 24/7 environment, and that is obviously temperature permitting."


but no, intel doesnt state anywhere the max vcore for ivy,
i tried several times to get a answer from them, spend weeks to find the answer, no go,
last mail i got from them, where i asked about the max vcore when ocing my 3770K,

Dear Fred,
Thank you for contacting Intel® Technical Support.
I cannot assist you overclocking your processor. You are free to overclock it, but we cannot give you any particular voltages. Please visit this web site http://www.intel.com/content/www/us/en/gaming/overclocking/overclocking-intel-processors.html where you find some guidance overclocking your processor.
Please replay back this email; do not send a new one.

i delidded because mine hit 105C in seconds at 4.5 ghz running prime,
the much lower temps gave me more headroom to oc higher, my chip isnt a very good ocer,
but i can run 4.8ghz at 1.420V vcore now, with very nice temps,

this is after 24H prime, 69-76-76-71C

worth it is hard to say, but imagine running the 4.7ghz with 20+C lower temps smile.gif
high temps is another thing that can make your chip degrade, besides high vcores..
i would rather run a high vcore with low temps, then a lower vcore with high temps ..lol

It depends when the program starts recording the temps - I doubt you are hitting 64C on idle. If you want to check idle temps, just run Coretemp and let the system idle for a few minutes.

I settled on a modest overclock of 4.4ghz at 1.23v its prime stable and the hottest core after 24 hours was 62c biggrin.gifbiggrin.gifbiggrin.gif so I am pretty happy with it
