ram pin 200 or 204

i purchased 2x2gb ram chips (pc2-5300) and did not realize until i received it that it was pin 204. i am trying to upgrade my old early 2008 macbook penryn so i can use it as a stationary home entertainment system and i think this particular model is the last few that uses 200 pin before apple switches to 204 pin. anyways, i don't know if that makes any sense but i need to know if i can use these or i need to buy two more ram chips. any input would be greatly appreciated.
