Hello,
I have an AMD build, with MSI 790FX-GD70 ATX AM3 790FX DDR3 4PCI-E16 CrossFire 1PCI-E1 2PCI eSATA SATA GBLAN Motherboard, and Phenom II 955 BE.

Currently I have 4GB of G.SKILL F3-12800CL9D-4GBNQ PC3-12800 4GB 2X2GB DDR3-1600 CL9-9-9-24 240PIN Dual Channel Memory Kit

I'm looking to add another 4GB or even 8GB, So I was wondering If I should just add couple of the same sticks or something different?

Also what is the difference between the memory that I already have vs G.SKILL F3-12800CL9D-4GBRL Ripjaws PC3-12800 4GB 2X2GB DDR3-1600 CL9-9-9-24 Core i5 1.5V Memory Kit
