How do I figure out what DDR RAM is in my machine?

[soop]

I've got an Asus A8n SLI deluxe, and it takes 3 kinds of RAM, but I have no idea what the 1gb stick in there actually is, so if I want to buy another stick they might not match.

How do I figure it out?

Hi.

U can use CPU-Z and check in the memory tab to know what model do u have.
