whats the Range of VCORE for a 24/7 OC in conroe?
for AIR of course

I've noticed temps climb a lot over 1.5v, like 6/7C per 0.05v. Up to that they look linear, I'd say 1.55v max. 24/7? I run 1.48v, till I see if a few start dying.

I personally don't plan on breaking 1.5v on air.

Seek and you shall find...
The chip will begin gettin' unstable once it gets too much, the "1.55v SHARP" is just plain BS... - I've ran 1.6125v on air for along time, tomorrow I get my watercooling head LGA775, and if it benefits I'll freakin' well go to 1.7xxx without even worrying. - ANd no, I've NEVER lost a chip due overvolting - and yes, A64 can handle more than 2.0v as well, they just dont benefit from it..

Id say its all off your temps more than a firm Vcore number.
P.S. O...M...G!!! Dont post ever again M Beier! Your current post count is 1337 heheh.

I'd run 1.4-1.5 max 24/7. Remember people, these are 65nm, not 90nm.

1,4 seems the max secure vcore
not?
If I had water I would run it 1.6 max but on good air 1.55
every chip differs greatly.

Depends on if your a regular user who wanna benefit from overclocking or more a "xtreme" user who just wants lots of power untill the next processor is released.
If youre a regular user I would stay below 1,4v and prefer to stay at 1,35-1,37 if the 1,4 doesn't give a noticeable increase in performance.
If you're more "xtreme" and anyway are going to buy the next CPU of the AMD/Intel line-up then listen to the other ones here. 1,5v and full throttle... but then your CPU proberly won't live more than 8-12 months before experiencing problems with electro migration (max stable clockspeed starts to decrease and the cpu operations will fail more often, but it won't cause your computer to crash).
As NickS said these chips are 65nm and they will take damage overtime due overvolting. No matter if your CPU runs at 30 degrees celcius at full load it WILL take damage of electromigration, but it takes quite some time even with serious overvolting before one will notice.
People seem to have forgot all about how the Northwoods died slowly... it's overruled by all the MHz one can gain by overvolting, because Intels CPU's scale really well when overvolted...
But if your xtreme a dead CPU once in a while is the price for a fast system :)

gotta have balls hey :) :toast: that's what it's all about :D

While yes higher voltage is ok for benchmarking its not worth it for 24/7. The reason why is once you get to a point your putting like 0.1v in for an extra 50Mhz or so. Your getting a lot more heat and very little extra speed.

probably 1.55v bios which = 1.5v real for me
I don't really plan to run more than that other than for benching

3.2Ghz should be atainable with 1.25-1.35V or so, shouldn't it? just curious.

Maybe with an ES chip, but definately not retail.

very true matt had to go over 1,4 for booting to windows @ 8x400 and it was instable
by the Intels datasheet is maximum limit 1.55V, but my E6600 must working on 1.6V, if this one die i will buy better one.

not on retails :(

I don't think we are giving the retails sufficient credit. They have the same potential as the ES chips. There are just two things working against it. First current BIOS revisions are ES oriented, though progress has been made in the last month. Secondly the ES chips people got for testing were probably in the top 10%. If you get a top 10% retail chip it should show the same overclockability as the ES chips ;)

Guess I am just lucky. I am 100% stable, 8 hrs orthos.
E6400 - DS3 with F3e at 8 by 400: 3.2 with 1.325 vcore
Big Typhoon - 30c idle - 39c load
At 1.3 its quickly unstable. I'm not really interrested in going mildly higher. I tried 3.6 and could get superPI stable but that was it and it took alot of over volting. Temps are right where I want them and performance is sweet.

Speaking of electro-migration, is the speed ofthat priocess a result of both heatand voltage, or just heat?
In other words - if you run your CPU at -40celcius with a phase-cooler, will that offset most of the accelerated electro-migration compared to running it on air + stock voltage?

e6300 and e6400 it is easily obtainable, yes but retail e6600s are another matter completely..

intel datasheet says 1.365 max volt for all conroes ^^
xlink

why wouldn't it be obtainable on a 6600? it is stocked higher and likely passes more intensive tests. I'm guessing l2 cache/transistor increase but it shouldn't have THAT muh of an effect.
and I'm assuming that ES stands for engineering sample, right? surprised by that, I always thought the first ones were thsoe with the most bugs. I guesse it's just intel handpicking in an attempt to get more hype from the enthusiasts at launch.

i don't see any 3.2s and 3.3s, but I'd expect them to fall somewhere below 1.4V the oen guy who specifically said he had a retail is somewhat inline with the ESs...

I am at 1.43v running my E6400 at 405x8 on aircooling. My max temp seems around 62C at full load.

Don't you have eyes?
it clearly says VAPOCHILL LS that's a phase cooling unit if you didn't realise. Plus that's only 1M stable with 1.65v.. ES step5s were able to hit that for 32M on air..

-StigmaThe magnetic forces as a result of voltage. ie, No the sub zero temps won't offset, the magnetic force will still be present regardless of the temps, whether its 60C or -100C. Electromigration will still occur, overvolting 24/7 or for long periods should only be done by people who are prepared to replace their processor, even though it may take 1 year for the effects to kill the proc.

Ok, good to know. I'l try to keep the voltage at reasonable levels then ~_^
I don't really care if the CPU dies in 3 years, as by then I will have either replaced it, or it will be worth nearly nothing anyway, but I dont want the degradation over overclocking-ability to advance too rapidly.

Personally I found that using above 1.4v in bios ( probably ~1.3 in windows) was very hot (high 70s under TAT *EDIT* with stock HSF). Its probably fine like this. It was stable, as far as I know, but I wasn't happy with that temperature.
I now have it under a TTST with a low speed fan at 3.2GHz 1.325vcore in bios (1.256-1.280 in windows).
Max temp probably 62°c.
I have a L629A 6400 *EDIT* retail
