hi.

i'm thinking of getting more memory for my laptop, which currently has 512-MB.

i'm guessing this comes in the form of 2x256-MB dimms:

my laptop is gateway mx6124.

it's ~2 1/2 yrs old.

i'd like to move up to at least 1-gig, or even 2 gigs, as that is what it seems this model supports.

but i also heard rumors about windows xp (which i use) not being able to use more than 1 gig.

is that true? what are your experiences.

i don't want to buy 2 gigs only to find i can't use it.

insight? advice?

gracias.

NO....the max ram for Windows XP (32 bit) is just a scooch over 3 gig's.

But XP (any version) will run very nicely on 2 gig's.
The performance on my own, home-made, PC took a real jump in the positive direction when I upgraded from one gig to two gigs, but when I upgraded to three gig's, I saw virtually NO performance increase at all in XP.

I did that primarily because I run Vista Ultimate on this same mobo, but from a separate HD.  Vista is much more Ram-Hungry than XP is.

Sounds like you made some good buys! 
Enjoy!
