I bought two of those from Amazon to make 1GB of RAM. They are working great with no problems. I checked my older memory and read the manual to make sure they are compatible with PC2100 DDR266 SODIMM.My laptop is Acer TravelMate 800 LCi.Thanks to Amazon for well documentation and well naming of products.
