need to find a matching RAM stick

[jjj807]

My mobo is a gigabyte ma57 sli nforce 570
I have 1 stick of OCZ PC6400 DDR2 800 dual channel kit model. It is 1 GB running at 4-4-4-15

Anyone know if I could find 1 stick of ram to match with this one? I can't get the same one because it only comes in 2x1GB packs. thanks!
