The Kingston Server Premier 48GB DDR5 5600MT/s ECC Unbuffered memory module (KSM56E46BD8KM-48HM) expands system memory capacity using high-density 24 Gbit SK Hynix M-Die integrated circuits. Designed for platforms requiring ECC Unbuffered (ECC UDIMM) memory, it combines a 5600 MT/s speed rating with real-time error checking for reliable continuous operation.

High-density ECC memory for workstation and server stability

Modern workstations and entry-level servers require substantial memory capacity to handle multi-threaded compute workloads, virtualization, and large datasets without compromising stability. This single 48GB 288-pin DIMM utilises non-binary 24 Gbit density DRAM chips, enabling higher memory capacity per slot compared to traditional binary memory configurations. The integrated Error-Correcting Code (ECC) functionality actively monitors data streams, detecting and correcting memory errors in real time to prevent system crashes and data corruption during prolonged operations.

5600 MT/s speed powered by SK Hynix M-Die architecture

Engineered to Kingston Server Premier standards, this module operates at 5600 MT/s with primary timing parameters set to CL46 (46-45-45). Built on a dual-rank (2Rx8) architecture using SK Hynix M-Die DRAM components, the module maintains strict signal integrity at a low operational voltage of 1.1V.

• Transfer Speed: 5600 MT/s for high-bandwidth data transfers
• Latency & Timings: CAS Latency 46 with 46-45-45 timing specifications
• Voltage: Low 1.1V standard operating voltage for efficient energy usage
• Timing Metrics: Row Cycle Time (tRCmin) of 48 ns, Row Active Time (tRASmin) of 32 ns, and Row Precharge Time (tRPmin) of 16 ns
• Refresh Rate: tRFCmin of 295 ns for precise DRAM refresh cycle management

Standard 31.25 mm profile and thermal tolerance

Physical compatibility and heat management are essential when populating dense server chassis or workstation cases. The module features a standard PCB height of 31.25 mm, avoiding physical interference with CPU coolers or tight expansion slot layouts. Designed for demanding operating environments, it supports an operating temperature range from 0°C to 95°C and a storage temperature range from -55°C to 100°C, backed by a manufacturer lifetime warranty.
