A:Answer First we should clarify that the product listed here is not a kit with 4 sticks, it says 2x64GB. This kit is specifically made to be used in a system that can use at least, or at most, 64GB.
Secondly, the kits that contain 4x32GB are specifcally made and tested to work together in a system that uses at least/most 128GB. That isnt the same as combining two matching packs of 2x32GB, as those packs may be in different batchs and not operate as efficiently in comparison to a proper 4x32GB kit.
