Most RAM in netbooks is slooooooooooooooooooooooow. I tried that once and it basically brought my system to a screetching halt with beechballs flying all over the place. You would be best off searching for some PC5300 RAM, as I believe that every netbook out there uses 4200. If you have 5300 in the netbook, though, you'll be fine.out a 2 gig ram stick out of an used netbook to bring it to 3 gigs
