Built on next-generation DDR5 SDRAM architecture, this memory class delivers significant advancements over previous DDR4 technologies in bandwidth, efficiency, and signal integrity.DDR5 RDIMM memory modules like the Kingston KTD-PE556D4-64G are widely deployed across data centers, cloud infrastructures, virtualization clusters, database servers, AI training systems, and high-end enterprise computing platforms. With a substantial 64GB capacity per module and a blazing-fast 5600MT/s data transfer rate, this category enables organizations to build systems that can process massive datasets, support concurrent workloads, and maintain consistent performance under sustained load.

High-Capacity 64GB Memory

The 64GB capacity places the Kingston KTD-PE556D4-64G within a high-density memory category designed for advanced enterprise workloads. High-capacity DDR5 RDIMMs enable servers to handle large datasets, in-memory databases, and complex analytics without excessive reliance on slower storage tiers.This capacity is ideal for modern applications such as virtualization, container orchestration, AI model training, and real-time data processing. By reducing memory bottlenecks, high-capacity modules improve overall system responsiveness and efficiency.

DDR5 Technology Memory

DDR5 SDRAM introduces a fundamental architectural leap compared to earlier memory generations. Memory modules in this category leverage higher base frequencies, increased burst lengths, and improved channel efficiency to unlock greater throughput per DIMM. The Kingston KTD-PE556D4-64G operates at 5600MT/s, delivering PC5-44800 bandwidth that dramatically accelerates data movement between the processor and memory subsystem.This DDR5 category benefits from dual 32-bit sub-channels per DIMM, allowing more efficient memory access and reduced latency under parallel workloads. As a result, applications such as virtualization, in-memory databases, analytics engines, and scientific simulations experience smoother execution and higher overall system responsiveness.

Registered DIMM (RDIMM) Memory

Registered DIMM memory modules incorporate a register (buffer) between the memory controller and DRAM chips. This design minimizes electrical load on the memory controller, allowing servers to support higher memory capacities and more populated DIMM slots without compromising stability. The Kingston KTD-PE556D4-64G belongs to this RDIMM category, making it ideal for enterprise servers that demand scalability and reliability.RDIMM memory is essential in systems where uptime and data integrity are critical. By reducing signal noise and ensuring consistent communication between the CPU and memory, this category supports stable operation even under continuous, high-stress workloads.

Optimized for Multi-Socket Server

DDR5 RDIMM modules are commonly deployed in dual-socket and multi-socket server platforms. The Kingston KTD-PE556D4-64G is engineered to meet stringent compatibility and performance requirements of leading server chipsets, ensuring seamless integration into enterprise-grade systems.

5600MT/s Speed and PC5-44800 Bandwidth

Operating at 5600MT/s, the Kingston KTD-PE556D4-64G is optimized for next-generation processors that leverage high-speed DDR5 memory interfaces. This frequency ensures balanced performance, thermal efficiency, and compatibility across a wide range of enterprise platforms.The 5600MT/s data rate allows servers to handle bursty workloads, high I/O operations, and parallel processing tasks with ease. This makes the memory category suitable for both compute-intensive and memory-intensive scenarios.

Dual Rank Memory Configuration 

The dual rank design of the Kingston KTD-PE556D4-64G enhances memory interleaving, allowing the memory controller to access multiple ranks efficiently. This improves overall throughput and reduces idle cycles during memory operations.Dual rank DDR5 RDIMM modules often outperform single rank configurations in server environments, especially when handling mixed workloads that involve frequent read and write operations.

Power Efficiency and Thermal Optimization

DDR5 memory introduces on-DIMM power management integrated circuits (PMICs), enabling more precise voltage regulation and improved power efficiency. The Kingston KTD-PE556D4-64G operates within optimized power envelopes, contributing to lower overall system energy consumption.This power-efficient design is especially beneficial in large-scale data centers, where energy savings directly impact operational costs and sustainability goals.

288-Pin RDIMM Memory

The 288-pin RDIMM form factor ensures broad compatibility with modern server motherboards and workstation platforms. Memory modules in this category adhere to JEDEC standards, guaranteeing interoperability and predictable performance across certified systems.This standardized design allows seamless upgrades and expansions, making Kingston DDR5 RDIMM memory a dependable choice for IT infrastructure planning.

Server and Workstation Integration

DDR5 RDIMM modules are specifically intended for server and professional workstation platforms that support registered memory. This category is not designed for consumer desktops, ensuring that enterprise systems receive memory optimized for stability and longevity.

CL46 Timing Memory

CAS latency (CL46) is a standard timing specification for DDR5-44800 memory modules. While numerical latency values are higher than DDR4, the increased clock speed and bandwidth of DDR5 result in comparable or improved real-world performance.This category prioritizes stability and consistency over aggressive latency tuning, aligning with enterprise requirements for predictable performance and reliability.
