Kingston Server Premier ECC Unbuffered DIMM 32GB 5600MHz CL46 DDR5 RAM

The Kingston Server Premier KSM56E46BD8KM-32HA is a 32GB DDR5-5600 ECC Unbuffered DIMM engineered for server and workstation platforms that demand reliable, error-correcting memory. Built to JEDEC standard specifications, this module delivers a tested latency of CL46 (46-45-45) at 1.1V, making it a straightforward drop-in choice for compatible Intel and AMD server platforms. At its core, this module is configured as a 4G x 72-bit (32GB) SDRAM array using a 2Rx8 dual-rank, eight-bank architecture spread across twenty 2G x 8-bit FBGA components. The x72-bit bus width — wider than a standard x64 consumer module — provides the extra bits required for ECC (Error-Correcting Code) operation. The die ECC implementation uses a x72 ECC layout with x36 per independent I/O sub-channel, allowing each of the two sub-channels to detect and correct single-bit errors autonomously. This architecture improves data integrity at the per-channel level without requiring host-side correction on every access. The module also supports Hard and Soft Post Package Repair (PPR), a DDR5-generation mechanism that allows individual DRAM rows to be remapped when persistent errors are detected — extending effective module life in always-on server deployments. Sideband management is handled through I3C/I2C, the DDR5-standard interface for SPD and in-band management access. Each module is housed on a 288-pin PCB measuring 1.23 inches (31.25mm) in height and uses gold contact fingers for reliable electrical connection. The board is both RoHS compliant and halogen-free, meeting environmental standards for enterprise procurement.
