The Samsung N145 Plus JP05 is standard equipped with 1GB RAM. A memory expansion is recommended. The DSP memory card (DDR3) provides 2GB of RAM for the above netbook. You can replace it with the new card the old card completely drive your dream. I ordered this card because I used a falsely original Samsung DDR2 - had ordered map, but unfortunately had to find that this is not intended for my netbook (!). A Bezeichnungswirrwar led additionally to misunderstandings. The DSP card fits tightly into the system and is compared to the original card much cheaper but just as good. The card is delivered in a box. It lies in a protective case and is protected at the same time of foam particles. It can not go wrong.
I hope this review is helpful and encourages you to buy the product.
