it depends what your mobo is.
1) if you buy another 256MB ram you can use it with the 128 = 384MB
2) you can just buy another 128MB and combine it with the other stick to equal 256MB
3) i recommend buying a 512MB stick and combine it with the 128 or dont for a total of 512/640
cause today the minimum is 256 for XP but 512MB for games. the average is 1GB and most people will say dont go past 2GB. is this a windows 98 or 95 computer...?
