suitable RAM for my pc

[Akash Mondal]

In my mother board user guide manual I have RAM capability list, here I can see SS/DS information like:- KINGSTON- KVR1333D3N9/2G- 2048MB- DS- Qimonda- IDSH1G-03A1F1C-13H- 1.5V......What dose this DS means, does it means I can use 2 x 2048MB of this KINGSTON RAM?
