Parts sold in kits (denoted by "K2," "K3" or “K4” in the part number e.g., HX424C15FW2K4/32) are packaged for use in Dual, Triple or Quad Channel configuration. The computers that support these configurations will typically access multiple memory modules as a single location of RAM with a wider bandwidth, if the memory modules installed within the same bank are identical. Therefore, Kingston ensures that only modules with matching components are packaged into Dual, Triple and Quad Channel kits.
