This is a genuine Kingston 4GB DDR3 memory module rated at 1600MHz, running as standard (non-ECC) memory rather than error-correcting server-grade RAM. It uses CL11 timings, an x8 chip organisation, a 1.5V standard-voltage design (rather than the 1.35V low-voltage DDR3L variant), and the full-size 240-pin unbuffered DIMM form factor used by desktop PCs and many entry-level workstations and servers of its era. It is single rank, meaning its memory chips are arranged as one logical bank per module, which is generally the easier configuration for a motherboard's memory controller to run at full rated speed alongside other modules. Kingston backs this module with a lifetime warranty, consistent with Kingston's standard desktop/value memory line.
