Memory for Acer Aspire One

Needed to upgrade the Acer Aspire One netbook, it only has 2G in it and was running quite slowly after some Windows updates. I did some research and was briefly alarmed that this model might have a 2G memory limit. However, it turns out that the model that I have, the AO756, can go up to 8G (these are apparently processor limits?). This Wikipedia page was very helpful in placing my netbook model number among the entire series of Acer Aspire One's, which is vast:

Here are the detailed instructions on how to do the replacement. This model is well designed; it is super easy to open the case and access the SIMM slots.

A couple of different sites advised that I get memory of type 204p PC3-10600 DDR3-1333 SODIMM.

I ordered a 4G SIMM from this vendor:

When the memory arrived and I opened the case of the netbook, I found that it had two SIMM slots, and only one was populated (obviously a 2G SIMM). I added the new SIMM to the other slot and when I booted the netbook, it registered all 10G.
