Can I upgrade the RAM in the Gigabyte GA-A55M-S2HP?

Yes. 4 slots, up to 16 GB seen working. It takes the same type of full-size sticks (DIMM).

The model name is printed on the board, usually between the memory slots or near the CPU socket. In Windows, open System Information and look at "BaseBoard Product"; it should read GA-A55M-S2HP.
