What is a "Kit" of memory?

If you have a multi-channel (dual, tri, or quad) platform and want to take advantage of the performance gain it offers, we recommend purchasing your memory in kits. A kit of memory will be 2 or more identical modules to be installed into 2 or more open memory slots in your system, or to replace one or more existing modules if open slots are not available.  An 8GB kit, for example, would have two 4 gigabyte modules (which would often be referenced as "2 x 4GB" in product specifications).


In order for your memory modules to perform best in your system’s multi-channel modes, all modules' specifications must be identical across associated slots. Our kits consist of matched modules, making it easy for you to purchase the matching sets needed to properly utilize these modes. For best results, refer to your system’s manual on how to install the matching modules into associated slots.


The advantage to buying a kit over simply ordering a collection of the same module is that kits are packaged specifically with identical matched parts guaranteed to work together in the same system and at the same speed, but we cannot guarantee that modules ordered individually will be identical to each other.


Crucial kit part numbers closely resemble those of individual part numbers, but with the addition of kit identifiers near the beginning, such as 2CP, 2K, 3KIT, or 4KIT (the additions will vary based on quantity, packaging, and reseller), to reflect the module quantities in the kit. For example, a kit made up of a pair of part number CT51264BF160B  (a 4GB DDR3-1600 SODIMM) would be reflected on packaging and product details with the part number CT2KIT51264BF160B. That kit part description would look like this, Crucial 8GB Kit (2 x 4GB) DDR3-1600 SODIMM.
