Double Height DDR4: 32GB Modules from G.Skill and ZADAK Reviewed
 

Two memory module companies, G.Skill and ZADAK, have developed a new memory format with double capacity DDR4 memory. These new modules put the equivalent of two standard modules onto one PCB, making one memory module act like two. Both companies have introduced 2x32 GB kits. As a result, these memory modules are double the capacity over regular DDR4 memory, with the downside that they are also double the height. We have tested both of the available kits using this technique, both coming in at DDR4-3200: the G.Skill TridentZ RGB DC DDR4-3200 and the ZADAK Shield RGB DC DDR4-3200.
