Yes, you'll only be overclocking the cpu and not the memory. The
mobile XP 2500 is unlocked and supposed to very good for overclocking.
I have two of the older unlocked Barton 2500+ and both are running
fine as much more expensive Barton 3200+.

You may need a bit more voltage for the cpu and the only thing to
watch out for is possible overheating. Some cpu fans are better than
others. Loud noisy fans does not necessarily mean better.


Also, if you really want to test stability try running Prime95 for 24 hours.
Be sure to monitor your temperatures though, it really taxes the system. I
was initially running a mobile Barton 2600+, with a 200MHz FSB setting,
using Corsair XMS3200 DDR (so the memory wasn't overclocked). Initially,
it gave the appearance of stability, but eventually there were system
lockups. I tested the system using with Prime95 (on the "blend" setting)
and sure enough, it failed after a few hours, regardless of the core voltage
setting. I lowered the FSB to 166MHz (while maintaining the same CPU speed)
and Prime95 ran fine even after 24 hours. I haven't had a lockup since.

Just because a system boots and runs some games for a few hours doesn't make
it completely stable, you have to run a torture test such a Prime95. Keep
in mind that the mobile Bartons have FSB ratings of 133MHz so the mobo's
timing table is going to be optimized for that speed regardless of the speed
you set it for.. Some mobiles are better than others for overclocking, you
just have to try it and see.
