The Kingston 128GB DDR5 6400MHz PC5-51200 Memory

DDR5 ECC Registered DIMM memory represents a major advancement in server and workstation memory architecture, delivering higher bandwidth, improved power efficiency, and greater reliability compared to previous DDR generations. Products within this category, including the Kingston KTD-PE564D4-128G 128GB DDR5-6400 RDIMM, are engineered specifically for mission-critical systems that demand consistent uptime, data integrity, and scalable performance. This category is widely adopted across enterprise servers, data centers, virtualization platforms, cloud computing infrastructures, and high-end professional workstations.

High-Capacity 128GB Memory Module

Featuring an impressive 128GB single-module capacity, this DDR5 RDIMM is ideal for data-intensive workloads such as virtualization, database processing, cloud infrastructure, artificial intelligence, and advanced analytics. The large memory footprint minimizes bottlenecks while supporting higher VM density and smoother multitasking.

PC5-51200 Bandwidth Memory

Operating at a blazing-fast 6400MHz data transfer rate, the Kingston KTD-PE564D4-128G achieves PC5-51200 bandwidth, delivering substantial improvements over previous DDR4 generations. This higher throughput enables faster data access, reduced latency, and superior overall system responsiveness.

DDR5 Technology

DDR5 technology significantly increases memory bandwidth compared to DDR4, with data transfer rates starting at higher baselines and scaling far beyond previous standards. DDR5-6400 modules deliver exceptional throughput, supporting modern CPUs with high core counts and advanced memory controllers. This increased bandwidth ensures smoother performance for parallel workloads such as virtualization, database processing, real-time analytics, and AI-driven applications.

Power Efficiency at 1.1V Memory

One of the defining features of DDR5 memory is its reduced operating voltage. Running at 1.1V, DDR5 RDIMMs consume less power while delivering superior performance. Integrated power management ICs (PMICs) on the module help regulate voltage more precisely, minimizing electrical noise and improving signal integrity across the memory bus.Lower power consumption translates to reduced heat output, enabling denser memory configurations without compromising thermal stability. This is especially valuable in data centers and enterprise environments where energy efficiency directly impacts operational costs.

Optimized CAS Latency and Stability

With a CAS Latency of CL46, this DDR5 module balances speed and stability, ensuring consistent performance under continuous enterprise workloads. The latency profile is fine-tuned to deliver dependable operation across supported platforms.

Registered ECC Memory

This memory module incorporates Registered ECC (Error-Correcting Code) technology, a critical feature for servers and professional systems where data integrity is paramount. ECC detects and corrects single-bit errors in real time, significantly reducing the risk of crashes, data corruption, and unexpected downtime.

Registered DIMM (RDIMM) Memory

Registered DIMMs incorporate a register between the memory controller and the DRAM chips. This buffering reduces the electrical load on the memory controller, enabling support for larger memory capacities and more installed modules per system. RDIMM architecture is standard in enterprise servers and supports greater scalability compared to unbuffered DIMMs.By improving signal integrity and timing stability, RDIMMs ensure reliable operation even in systems populated with high-capacity memory modules. This design is particularly important for dual rank and high-density DDR5 modules operating at elevated frequencies such as 6400MHz.

Dual Rank Configuration 

Configured as a dual-rank DDR5 module, this Kingston memory DIMM enables more efficient memory access patterns and improved parallelism. Dual rank design enhances overall bandwidth utilization, especially in multi-socket server environments.

288-Pin DDR5 RDIMM Form Factor

This module utilizes the 288-pin DDR5 RDIMM form factor, ensuring compatibility with the latest server and workstation motherboards that support DDR5 registered memory. Precision engineering guarantees a secure fit and reliable electrical contact.

6400MHz Data Rate and PC5-51200 Memory

Operating at 6400MHz, DDR5-6400 RDIMM memory delivers a substantial increase in data transfer rates. The PC5-51200 designation reflects the module’s ability to transfer up to 51.2GB/s per channel, supporting faster application response times and reduced processing bottlenecks.High-frequency DDR5 memory is particularly beneficial in modern server platforms where CPUs feature numerous cores and threads that rely on rapid memory access to maintain peak performance.
