pctechtv Posted March 28, 2018 Share Posted March 28, 2018 Looking at ram in retail stores, I notice a lot have different revisions (e.g., rev 5.39). My question is if you mix these does it matter? I was in a store trying to buy 4 x 8GB of DDR4 ram. They were selling them in packs of 2 x 8GB. The only two in stock had different revision numbers. I waited until I could ask the question.

Corsair Employee Corsair Art Posted March 28, 2018 Corsair Employee Share Posted March 28, 2018 From my experience, I've seen compatibility problems between kits even if they are the same version. Link to comment Share on other sites More sharing options...
meeshu Posted April 1, 2018 Share Posted April 1, 2018 Yes. Generally, there is better chance of inter-module compatibility if the module revision is the same, but there is no guarantee. If wanting 4 memory modules (4 x 8 GB), then it is strongly recommended that a quad channel kit be bought as all four modules within the kit have been tested for and guaranteed to be compatible with each other. It is possible to get two 2 x 8 GB dual channel kits (with the same module revision, or with different module revision) to work together (compatibly) in some cases by making some adjustments in BIOS, but there is no guarantee of success. It may require trying several 2 x 8 GB dual channel kits until a compatible combination is found. Link to comment Share on other sites More sharing options...
