DDR2 ram has a sticker on the dimms labelled PC2-xxxx DDR3 ram has a sticker on the dimms labelled PC3-xxxx(x)

Even if there is just a barcode on it, you can google the number and it will show you what type of memory it is.

You can also visit a site like kingston.com or crucial.com, enter the details of your computer make and model, and it will give you a list of compatible memory.
