Max safe Vcore for Athlon XP----

[Grentarc]

Question for all you guys and gals......
What is the max safe voltage for an Athlon XP 2400+/2600+ when it is wanted to live for a long time?

Getting an Abit AT7-Max2 (no need for Vmods-- Bios has up ro 2.325 Vcore and 3.25 Vmem:-D ) Either the 2400+ or 2600+-- depends on which is available at the time-- gonna be run in a Vapochill (removes 130watts of heat at -5°C)... Still waiting on the Bios to suppor the 1/6 divider option.
Any help would, of course, be helpful!
thanx

IMHO:
2.0v would be the max with exceptionaly high end cooling. (air or water, not sure about cyrogenic). I would feel more comfortable with 1.80 - 1.85 for long term. That's where mine live.

[Holst]

my CPU's tend to run 2.2v (palomino's)
Ive never had any problems with one dying.

With a newer Tbread im not sure. I think 2v is an ok cutoff.

It depends on how many more mhz you can get for the voltage increase.. if you only get 50mhz moreby going from 2v to 2.2 then id stick with 2v for long term use.

As I change CPU every 6 months im not too worried about them living one year or five (although there is the risk one might die after a week, but im willing to take it)

sounds good

In my years of overclocking, I've never outright killed a chip from too much voltage, I have however found that extremely high voltages for long periods of time can make a chip unstable and flakey. Several years ago I ran a K6-3 at 3.2V(default was 2.2 or 2.4 or something along those lines) for around 6 months, then one day the system just started crashing every now and again, swapped the chip and everything went back to normal. Basically I agree with Holst, don't bother chasing after those last couple tics-per-second with extreme voltage, they probably aren't worth it.

I've run my XP2400 at 2.2v for an hour or so during a benchmark session. Day to day though I only feed it with 1.85-1.9v because like Holst mentioned, it's just not worth pushing xtreme voltage for only a few MHz increase.

You sufferd from electromigration(not sure of the english name)

I know about a guy that runned his duron 600@1200 with 2.3V(watercooled) for a year without suffer any electromigration and now he has runned a XP 1600+@1.95GHz a few monts with a max vcore of 2.25V(water+tec)

I runned my 1600+ before @ 2.15V with bad watercooling(60C on-die)
My stepping is AGOIA but with my cooling i need like 2.1V for doing 1800MHz stable. But i could run 1750MHz with 1.76V. So i probly would do much better with better cooling.

My Duron 600@1102 eventually died, after 3 years at that speed and 1.94v aircooled. I can only assume it was electromigration. As for my current XP, it stays below 1.9V.

[Marci]

I run day to day at 1.95-2.1v, and when I'm pushing it for benching my vmod will allow upto 2.4 to cpu, and 3.4 to mem. Mobo at default gives me upto 2.325 and 3.25 (Abit KD7-Raid).

All cooled with water.

I guess it depends on the chip... my 1600+ won't go any higher than 1.833ghz no matter what voltage I use.

According to the new docs, max on the new chips is 2.1v for the 2400 and 2600, 2.15v for the 2700 and 2800. Its 2.2v for the palaminos. I wouldn't go past 1.9v with air cooling... I have never seen, nor heard of, an athlon failing at anything below 2.1 though.

where did you find these docs?, can you post a url??
