Kingston Server Premier 128GB ( 1 x 128GB ) 6400MTs DDR5 ECC Memory KSM64R52BD4-128MB

Kingston Server Premier 128GB (1 x 128GB) 6400MTs DDR5 ECC Memory KSM64R52BD4-128MB redefines what a single memory module can bring to modern servers and high-performance workstations. Engineered by Kingston, this 16G x 80-bit (128GB) DDR5-6400 CL52 SDRAM module combines massive capacity, industry-leading ECC protection and next-generation DDR5 bandwidth to power virtualization, large-scale databases, analytics workloads and mission-critical applications. Built from forty 8G x 4-bit FBGA components in a 2Rx4, x80 configuration, it is purpose-designed for systems that demand uncompromising stability and predictable performance under sustained loads.

Benefits

• Maximum memory density in a single DIMM: A 128GB single-stick option simplifies upgrades and minimizes slot usage while enabling servers and workstations to host far larger memory footprints for VMs, in-memory databases and multi-threaded compute tasks.
• Data integrity and uptime: ECC on-die and x80 ECC architecture detect and correct memory errors proactively, reducing the risk of data corruption and system crashes—essential for mission-critical deployments and sensitive compute environments.
• Performance for next-gen workloads: DDR5-6400 bandwidth combined with 1.1V power efficiency gives applications faster data transfer rates and a higher sustained throughput compared to earlier generations, improving responsiveness in data-intensive operations.
• Efficient power profile: Operating at a 1.1V typical voltage, this module balances high frequency performance with improved power efficiency—helpful in dense server environments where thermal and power budgets are tightly managed.
• Confidence for builders and integrators: Kingston’s engineering pedigree and PC-Builder-rated classification make this module an easy, reliable choice when specifying memory for custom builds and enterprise systems.

Key features

• DDR5-6400 Performance: Delivers high-bandwidth DDR5 performance at 6400 MT/s (PC5-51200), accelerating memory-bound tasks and improving throughput for modern server applications.
• ECC x80 Architecture (2Rx4): 16G x 80-bit design with on-die ECC and two independent I/O sub-channels ensures robust error detection/correction across the module, supporting stable long-term operation in production systems.
• Massive 128GB Capacity (1 x 128GB): Single-module 128GB density enables flexible scaling—install one for large single-DIMM capacity or populate multiple slots for terabyte-class configurations without consuming excessive board space.
• Optimized Latency and Voltage: CL52 latency tuned for DDR5 operating at 1.1V typical, providing a balance of latency characteristics and power efficiency suitable for continuous server workloads.
• Server-Grade Construction: Built from high-quality FBGA components in a 2Rx4 layout and validated by Kingston for server use; PC Builder Rated to simplify integration into custom workstation and server builds.

Additional technical notes and deployment guidance

• Configurability: Typical server configurations will use 4 or 8 memory slots depending on motherboard. Examples: 4 x 128GB = 512GB total; 8 x 128GB = 1024GB total. Plan your motherboard and slot population accordingly to achieve the memory capacity and channel configuration you need.
• JEDEC compatibility: This DDR5 module will boot at the JEDEC standard frequency out of the box. When installed in custom systems, Kingston’s testing uses the highest standard frequency supported during system validation. Note that the ultimate frequency your motherboard supports may vary; maximum motherboard compatibility is not guaranteed to match every memory specification.
• Form factor and identification: MPN KSM64R52BD4-128MB, UPC 740617346787—intended for server-class motherboards that support DDR5 ECC RDIMM modules with x80 ECC formatting.
