Kingston Server Premier ECC Unbuffered DIMM 16GB 5600MHz CL46 DDR5 RAM

The Kingston Server Premier KSM56E46BS8KM-16HA is a 16GB DDR5 ECC Unbuffered DIMM engineered for server and workstation platforms that demand data integrity and operational consistency. Built around a 2G x 72-bit architecture using ten 2G x 8-bit FBGA components in a single-rank (1Rx8) configuration, this module delivers a total capacity of 16GB across a 72-bit bus width that includes the dedicated ECC lanes. The module operates at DDR5-5600 with JEDEC-standard CL46-45-45 primary timings programmed directly into the SPD, ensuring plug-and-play compatibility with JEDEC-compliant server platforms without requiring manual tuning. The operating voltage is 1.1V for both VDD and VDDQ, with VPP rated at 1.8V and VDDSPD running between 1.8V and 2.0V — all standard DDR5 server power rails. A key architectural feature is Die ECC combined with an x72 ECC implementation across two independent x36 I/O sub-channels. This dual-layer error correction approach detects and corrects single-bit errors at the DRAM die level before data reaches the memory controller, then again at the channel level — providing a robust safety net for mission-critical workloads such as virtualisation, database operations, and always-on services. The module supports 32 internal banks and includes both Hard and Soft Post Package Repair (PPR) capabilities, enabling in-field row repair without full module replacement. Sideband communication is handled via I3C/I2C interfaces for compatibility with modern server management and SPD hub ecosystems. All 288 gold contact fingers comply with standard DDR5 DIMM keying, and the PCB height measures 1.23 inches (31.25mm). The module is RoHS compliant and Halogen-Free, meeting environmental standards for enterprise deployments.
