Hi,
From the Product Description:
RAM Technology: DDR3 (Dual Channel)
RAM Slots : 4 x 240-Pin
RAM Speeds: DDR3 800, DDR3 1066, DDR3 1333, DDR3 1600 (O.C)
Max. Memory Support: 16GB
The m/b will support 16GB so your 4 x 2GB is fine.
The m/b also supports DDR3 so your choice looks fine.
Dalo ( hardware specialist ) will hopefully confirm :)
