X3110 @ 4G Voltage too high? - Page 5

Then im ok, im only running at 1.4v which is well under the electron migration curve for a 65nm quad. (although electron migration is constantly happening in any electrical circuit with a close proximity) but from what i understand its sped up exponentially bu massive overvolting.

to the thread starter. electromigration in a nutshell is when the electrons have enough energy to start punching through the insulating material that seperate the ground from the positive. the higher your voltage the more energy those electrons have and the harder they punch. the closer everything is the easier it is to punch through. with this though the punch doesn't have to go all the way thorugh in one shot. it can do it over time also taking out small chunks as it goes. this will lead to mroe leakage current, higher temps, less stability and higher voltage required (which causes even more damage) to run the same speeds.

this mainly depends on voltage, not temps. so you can do what you want and you might be fine but your doing so at your own risk. but what your doing is running voltage that is even a little high for a 65nm chip and running it through something that is almost 30% smaller.

Intel actually says 1.3625v as the max, and people are burning chips at 1.4v. Unless you're on water, don't go over 1.4 IMO. It's safer. And change that multi to 9 lol

Check these links for the VID voltage range:
Xeon E3110: http://processorfinder.intel.com/det...px?sSpec=SLAPM

Core 2 Duo E8400: http://processorfinder.intel.com/det...px?sSpec=SLAPL

Ridiculous difference.

you can edit your post rather then post twice in a row you know

as far as it goes though you are right with what the VID range is that though is not the absolute max rated voltage for the cpu. that voltage is rated at 1.45v

Well said, I also laugh when I hear these CPUs will "fry" when taken above a certain vcore. The largest group of Woldale owners giving feedback on the issue are at XS, and they dont call the place Xtreme Systems for nothing, its regular practice to apply insane voltages there no matter what the risk to hardware damage is (highest I've seen is around 1.85v on the Wolfies). Theres a thread there with a poll for people reporting on degradation. To my knowledge no ones killed their CPU yet, some have reported degradation which means that if they're doing 4.5 ghz at 1.45v, after time they may need 1.46v to maintain stability at that speed. If thats all degradation is, I wont lose any sleep over it. But its still too early in the Wolfdales lifespan to come to any conclusions so I'm still cautious and 1.3625 atm is my limit. I may increase it when I get a better feel for it and see a definitive trend on the scale and extent of the degradation, but as of now It doesnt look as serious as its made out to be, ie, as in "fried" or completely non-functioning chips.
Well.. I've used this CPU for quite long @ 1.55V
there's no problem with it so far, I don't know who Tricky is but I think he got a defected CPU.

so 1.3625 is max for daily? And 1.45 for max but no promised lenght of life right?

Well from the looks of this post it depends who you ask.

I'd say your ok below 1.45 if intel max recommended max is 1.45 (which i think it is for the e8400) the 1.3625 is the highest VID, thats the highest max default voltage needed to run at stock speeds. Personally, and this is MY opinion, I dont like getting to close to recommended MAX anything, my Q6600 is max 1.55, I'll stay 1.50 or lower, max temp is 72, id stay 68 or lower load temp.

I guess over at XS and some here, thr say you can go higher than what intel recommends as MAX voltage. But I have this odd feeling that they wont be helping you buy a new cpu if something should happen to it.

Temp is not an issue here, 8Hrs prime gets me the highest temp of 56.

and if I change my multi to 9 X 445 to make it 4GHz, my ram gets slower i don't want that, with 12:10 ratio to the cpu 72ns latency, with 1:1 ratio to cpu i got 64ns

Yuck ..is there any way to tighten them beyond what your current settings are?

If you would like some help with them, PM me.
