Do: # dmidecode | less and look for the entries for the existing RAM you have. It will also tell you if you have any unpopulated RAM slots ("No module installed"). It won't tell you the maximum size RAM each slot will take. For that, you would need to look up the specs for the motherboard or system (you can find the model number in the dmidecode output too). Or you can go to the website for a memory vendor such as Crucial or Kingston and enter your model number, and it will tell you what RAM is compatible and what it costs.
