Kingston Technology KVR13S9S8 / 4 ValueRAM memory 4 GB DDR3 SO DIMM 204-pin (Personal Computers)
We must be absolutely certain to buy such a product but taking his time, you do it, even to set up a memory card that I had never done on a laptop! Recommend site for its seriousness and its prices. Impeccable packaging, which does no harm!
