O/C'ing a XP-M 2400+ how far can I go?

OK here's what I've got

AMD AthlonXP-M 2400 1.8GHz
Aopen AK79D-400VN mobo (nForce2 Ultra400)
Thermaltake Volcano 11+ pure copper HSF with a Tt thunderblade 80mm fan
512MB Mushkin Basic PC3200
Antec True330 330W PSU

currently I have it overclocked to 2.2GHz (200x11 @ 1.6v) perfectly stable, idle temps are around 42-45 degrees C, load 48-50 degrees C. As soon as I bump it to 2.3GHz (200x11.5) I have to crank the voltage to 1.7v just to stabilize it, even then after its been running awhile it gets unstable. The temps get to about 52-53 degrees C load. Can I get any higher with this? I've seen others get higher but without the problems.
 
what stepping on that chip? It is a crapshoot, some are destined to be 2.2~2.3 gig chips.
I would try it at 1.75 and 11.5 x 200. If it runs stable and under 55C under load, you are golden.
If it is stable but a bit hotter, then the cooling is the holdback, IMO.
 
I have two 2400+ Mobile chips. One runs at 2.7 Ghz, and the other 2.65 Ghz. Most any 2400+ with a good stepping will hit 2.6 Ghz without much effort. As the FSB rises, expect to dish out the juice just as with non-"M" CPU however. The low-watt rating is it's idle rating, NOT it's rating under normal use. You DO get the cream of the 2400+ crop though, and that in itself says something.

 
If your board can adjust the voltage in 1/4 increments then try 1.725 if not then go to 1.75volts, that should hold it stable for you.
 
OK see I'm wary of messing with voltages too much. I'll have to check the stepping - I checked it once but I foget what it is
 
I'm surprised you are running that hot on a pure copper cooler if you are only pumping 1.6v into it.... mine idles at around 38 or so and runs load at at most 48... and I'm at 2.5 Ghz and i think 1.7-.18v so... hmmm what thermal paste are you using?

Click to expand...

what does it mean when you say "check the stepping"?
 
lol keep it at 2.2 or lower man. Personally I dont c the difference between 2.2(1.575V) and 2.4(1.775V) on my 2500m. but its a big voltage jump for me to get from 2.2 to 2.4 almost .2 volt on my CPU. Theres only 100-150 pts score difference in 3dmark03. So best setting is at 2.2 for u I guess.

AMD 2500M
NS7-S
ENermax COolergaint
 
Check the stepping as in pull the heatsink off the CPU and read the numbers on the CPU of course 😉 I still haven't done that yet, it is a job to get that heatsink off there, then I gotta redo all the thermal goop stuff.

I'm using the generic thermal goop that came with the heatsink - very cheap stuff but it is better than nothing. I need to get some arctic silver 5 but haven't done that yet. Also I have lower-RPM fans to make my PC quiet. 2500RPM is the fastest of them all, that is on the CPU, the case fans (2 front 2 back) are like half that speed I think.
 
How do you know what stepping are better than others? I have AQYHA0440UPGW on a XP-M 2400 45W. Where do I stand?
 
people generally say a IQYHA will overclock higher than a AQYHA . but that isnt always true. best thing to do is try it out and see what it does for you . each chip is different
