I have bought on a shop a 4GB DDR3L 1600 CL11 UDIMM CT51264BD160BJ and it has not worked on the computer. (this memory has only chips on one side, 8 chips) I want to change this module so I had gone to Crucial site and run the Advisor tool to know which memory is compatible. I get this as result: 4GB DDR3L 1600 CL11 UDIMM CT8961405 which I can't figure out the difference with the one that I bought and is failing. Can someone tell if these two memories have some different specs? Different density or something?
