well i did some research and found out that i need 200 pin ddr2 2700. so i plan on getting 2 gigs of that. but just after i made this post i opened my computer up and saw another expansion slot for an extra hard drive. so i decided just to add another hard drive and save some cash instead of buying another copy of XP.
so right now the only problems that are prevalent is the if the motherboard will be able to support the new dual core processor

ive decided to only go to 1.6 because this laptop is a desktop replacement and i do not want overheating to occur.
