depending on what u use the laptop for... installing more ram may not make anything faster. since u alreayd have 512mb(504 imguessing cause integrated somethingor other is using up 8), if u install more ram, it will not be used untill 512 is used up. typically 512mb's of ram isnt totally used up unless u do - a lot of gameing, photoediting/audio/video editing. stuff like that.
