I have an Athlon XP 2400 Mobile on a Albatron KX18D Pro Mobo. I have a volcano8 and a smart fan on the processor. Right now I run at a very stable 2.2ghz (200*11 @ 1.625V) with idle at 39 and load at 45 C. But I can't go any higher. I tried going to 200*11.5, and put the voltage up as high as 1.7 V, where it would boot fine, but 4 min into Prime 95 I would get errors. Why am I limited at 2.2ghz when i've heard how it can go higher? My one thought is the power supply? I have a 350W supply what came with my case. The individual ratings are 3.3V/24A, 5V/35A, 12V/12A. So what do you guys think?
Overcloking stopped at 2.2 for Athlon 2400 Mobile?

1.75v shouldn't be a problem at all...i can run my mobile 2400 @ 12x200 (1.8v) w/ abs. no problem w/ less than stellar cooling
Dont worry until you are in the 1.8V zone, anything below that and you can feel alright about your PC lasting more than a year.
well...i would like this computer to last more than a year...my last computer i bought 3.5 years ago, it was a P3 1Ghz...
Well Im not sure how long PC's at voltages past 1.8 last but Im thinking 2-3 years for voltage under that.
1.85 vcore here with 43.5 full load in a hot apartment. Get some good cooling and you'll be fine
If I were you, I'd at least try to see how stable it could be by bymping up the voltage - once you know how high it would run stably at each voltage level, you can decide what to do. 1.8v territory will not kill your chip right away. I don't know if the longevity of the chip Will be affected by running it for a short period of time for testing purpose. But I'd say it'd be worth a shot.
I'm pretty sure it's the power supply. i unpluged my 2nd HD and both cd drives and it went to 2.3 with 1.675 stable. So i think just getting an Antec 350 will fix the problem. How high should i expect the 2400 to go with an ample PS?
it varies from chip to chip of course, but you'll probably get between 2.4GHz and 2.6GHz on air. What's your stepping?
unfortunatley i dont know my stepping. i didn't look before i mounted the heatsink :-\ so i would like to know, but I don't think it's worth taking it off and remounting it just to check that. And 2.4-2.6 sure seems high on 1.725, i should really be able to get that high? maybe i need to downclock my ram? could that be holding me back? but i wouldn't think so because it is stable running at 410mhz, and then i increase the multiplier and it's not stable, but the multiplier shouldn't effect the ram, right?
i too think that your psu is what's holding you back. i'm currently working on my friend's mobile 2400, and the only thing i'm really worried about is the psu. its a 430W generic hurting to support the mobile with ocz 3200+ ram, and nf7. i cant get it stable even at 2.2ghz at 1.65-1.75V. i'm also haveing a hard time hittin 200fsb at all.
Try running your memory in single channel mode. It's almost as fast, and much more stable. Mine wouldn't even load windows in dual channel mode.

Voltage doesn't kill processors... heat kills processors.
-Unkown... but good saying
Dont worry until after above the 1.8xx range. Ive seen some go as high as 2.1V. I certainly wouldn't go that high im happily running at 1.8V right now. I was hesitant my first time but its not a big deal. Make sure you have adequate cooling tho.

no voltage kills processors heat just shuts them down 
unless you have over 85c or so to where it melts them
i've fryed like 5 cpu's with voltage while using subzero cooling and air cooling with similar results
just be carefull with these .13u chips

Obviously at a point voltage will kill a processor. But that point is likely around 2.3 or soemthing. Mostly the heat kills processors. Also before you move the voltage up make sure to get an accurate reading. That way you know whether your board overvolts or undervolts.

electron migration guy
maybe you could push over 2v with some .18u chips and get away with it if ya had good cooling
but these .13u chips fry from that much voltage even if yur temps are below 0c
athlons xp's for example tend to go out around and above 1.75v in my experience
people do push them over 1.8 and even 1.9+ but this is not safe because the gate size is so small
most people try to keep their .13u P4's under 1.68v or so regardless of cooling
but you can believe whatever you want
