I want to add 1GB memory to my lenovo s10 netbook, but don't know which is the correct memory model number.
On Lenovo website, it shows my netbook uses: 1-GB DDR2-533 SDRAM SO-DIMM (PC2-5300) card, but there is no such kind of memory.
It's either DDR2-533 (PC2-4200) or DDR2-667 (PC2-5300).
Which one should I use? Why? Thanks.
