My computer only recognizes part of the memory that I installed. I checked to make sure this part met the specs for my computer. Did I get the wrong item?

Possibly. Memory modules can be built in a variety of ways. Consult the owner's manual for your computer, to insure your computer can recognize the size of module you installed. Also check our product configurator to make sure you purchased the correct item. If you are uncertain, please contact us for further assistance.
