Planiram povecanje memorije za notebook jer je na njemu
Vista, pa me zanima:
- Sta da uzmem od navedena dva modula posto su slicnih cena?
- Koja je memorija brza i stabilnija?

Planirao sam 2x2GB 800MHz ali nisam siguran da ne pogresim.

Pretrazio sam forum ali nisam nasao temu o memorijama
za laptopove.
