My system has 4gb mem. Specifications of the mem are below.
G.SKILL 4GB (2 x 2GB) 240-Pin DDR3 SDRAM DDR3 1333 (PC3 10666) Dual Channel Kit Desktop Memory Model F3-10666CL8D-4GBHK

Now I wanna buy 4gb more. Should the new 4gb's specifications for the DDR3 #### (PC3 #####) match the old one's or not?
Say, would the following work well with my current system?
G.SKILL Ripjaws Series 4GB (2 x 2GB) 240-Pin DDR3 SDRAM DDR3 1600 (PC3 12800) Desktop Memory Model F3-12800CL9D-4GBRL
