In most eval kits I saw ( I also tried designing my board) I found that they use 1GB DDR3 (two chips each 4Gbits and each is 16-bit width) and once chip select is used. The chip select 0 of the Cyclone 5 SOC is connected to the two DDR3 chips.

Does this mean I can use 2GB DDR3 for the FPGA or the SOC?
