Dell Latitude 5501 64GB of RAM? Yes!
Imagine my surprise when my Dell Latitude 5501 was able to be upgraded to 64GB of RAM when the specifications state it has a maximum of 32GB. My guess is marketing. They want to sell you a more expensive model that officially supports more RAM. Here is a link to the RAM that worked for me. Anyway, if you are looking to upgrade your 5501, go ahead and move to 64GB.
