The Kingston KSM64R52BD8-32MD 32GB 6400MHz Memory

The Kingston KSM64R52BD8-32MD belongs to a professional category of DDR5 ECC Registered DIMM (RDIMM) memory modules engineered for modern data centers, enterprise servers, cloud infrastructure, and mission-critical workstation platforms. This category focuses on stability, scalability, and sustained performance under heavy multitasking and continuous workloads. With a capacity of 32GB per module and a high operating frequency of 6400MHz, PC5-51200 bandwidth, this class of memory is purpose-built to support next-generation processors and chipsets that demand higher throughput and improved power efficiency.

DDR5 Technology

The DDR5 memory standard represents a fundamental evolution in memory technology, particularly within the registered DIMM segment. This category emphasizes improved signal integrity and scalability, which are critical for multi-socket servers and high-density memory configurations.

Higher Bandwidth and Data Rates

Operating at 6400MHz, DDR5 RDIMM modules deliver substantially higher data transfer rates than previous generations. The PC5-51200 specification indicates a peak theoretical bandwidth of 51.2GB/s per module, enabling faster data movement between the CPU and memory subsystem. This increased throughput is essential for compute-intensive workloads such as virtualization, artificial intelligence inference, in-memory databases, and real-time analytics.

ECC Registered Memory

ECC Registered DIMMs are specifically designed to improve memory stability and signal quality in enterprise systems. Unlike unbuffered memory, RDIMMs incorporate a register that buffers command and address signals, reducing electrical load on the memory controller.

Signal Integrity and System Stability

The register on RDIMM modules plays a critical role in maintaining signal integrity, particularly in systems populated with multiple memory modules. By re-driving control signals, registered memory enables higher module counts and greater overall capacity without compromising reliability.

Error-Correcting Code (ECC) 

ECC memory detects and corrects single-bit errors and identifies multi-bit errors, significantly reducing the likelihood of data corruption. In server environments where applications run continuously and handle sensitive data, ECC Registered DIMMs are a foundational requirement rather than an optional feature.

Optimized for Multi-Socket Server 

This memory category is engineered for compatibility with enterprise-grade CPUs and chipsets from leading manufacturers. RDIMM modules are commonly deployed in dual-socket and quad-socket servers where memory reliability and scalability directly impact system performance.

Memory Latency and Timing 

While DDR5 operates at higher latencies numerically, the increased clock speed compensates by delivering faster effective access times. CAS latency 52 is optimized within the DDR5 framework, ensuring balanced performance across a wide range of workloads.

Power Efficiency

DDR5 RDIMM modules operate at lower core voltages compared to DDR4, contributing to improved energy efficiency. The integration of a power management IC (PMIC) on the module enables more precise voltage regulation, reducing power loss and thermal output in dense server configurations.

Design and Form Factor

The 288-pin DIMM form factor is a standard across DDR5 memory modules, ensuring compatibility with modern server motherboards designed for DDR5 RDIMM support.

288-Pin Registered DIMM 

The pin configuration of DDR5 RDIMMs differs from DDR4, preventing incorrect installation and ensuring proper electrical characteristics. This design supports higher signal frequencies and improved channel efficiency.

High-Performance Computing

Scientific simulations, modeling, and big data analytics require rapid access to large datasets. DDR5 6400MHz memory modules help reduce memory bottlenecks in compute clusters.
