You can use either a 32bit or 64bit operating system (OS) for 4GB of RAM. 4GB of memory is the limit a 32bit OS can handle, this includes any memory that your graphics card has, so your computer may recognise only 3.5GB of RAM if you have a 512MB GPU. You will need a 64bit os that will use all of the ram.
