Higher than 4 GB only makes sense if you have a 64-bit OS. The usual odler 32-bit OS only sees 4 GB, so everything more is not used.
Now go to www.crucial.com to find out what the maximum RAM for your PC is, and what they sell. Then buy what you need.

I have an emachines 525 series R3 laptop. The original hard drive has been replaced with a Kingston SSD drive. I want to increase the RAM to 4gByte or higher. Is this possible and where canI buy the memory card(s)?
