The below images show the 3 main types of memory available for a PC, they also show the physical differences.
Please note the below information is just a quick guide that should help identify what memory your motherboard will take. Memory is available in different speeds so you will still have to check what speed memory your motherboard will take or what speed your existing memory is.
DDR RAM

DDR memory has 184pins and it has one cut out slightly off centre.
DDR2 RAM
http://forum.novatech.co.uk/files/DDR2.jpg
DDR2 memory has 240pins and it also has one cut out slightly off centre.
RD RAM or Rambus
http://forum.novatech.co.uk/files/RD.jpg
RD RAM has 184pins and two cut outs in the middle about 1cm apart. RD Ram normally has to be installed in identical pairs (please check this in your motherboard manual). Some boards that use RD Ram have terminators in the free memory slots. A terminator is circuit board the same size as a stick of RD Ram, sometimes they have nothing on and others have a few resistors.

If you are unsure what memory is installed in your system its best to open the system and have a look at the stickers on the memory. Alternatively you can use a program called CPUz to check. This is a free download available form the below link.
