The computer has a 2 2GB sticks with 'pc2 6400u 666 13 e1' on it. To get extra stick pair (i.e. 2*1GB) which of these codes are important (and what do they all mean). I tried googling.
Will 1GB sticks with the following work.
PC2-6400U-666-12-ZZ
PC2 -6400U 666-12-E3
PC2-6400U-666-12-D0
PC2-6400U-666-13-D1
Or is it anything starting PC2-6400U-666 is OK?
