This category focuses on stability, scalability, signal integrity, and reliability under continuous workloads, making it suitable for data centers, virtualization hosts, cloud infrastructure, AI acceleration platforms, and mission-critical enterprise systems. DDR5 RDIMM technology introduces architectural refinements that go far beyond previous DDR4 generations, offering increased bandwidth, improved power efficiency, and enhanced error protection.

32GB High-Capacity Memory Module

The 32GB capacity of the Micron MTC20F1045S1RC64BH1 module offers ample space for modern server workloads. Large memory sizes are essential for applications such as database management, virtualization, big data processing, and cloud computing. This capacity allows servers to run multiple virtual machines simultaneously while maintaining system responsiveness, enabling organizations to maximize server utilization.

DDR5 PC5-51200 Performance Classification

The PC5-51200 designation identifies this memory module as capable of delivering up to 51.2GB/s of theoretical bandwidth per module. This classification reflects a substantial leap in throughput compared to previous memory standards, enabling modern CPUs to process data-intensive workloads more efficiently. The DDR5-6400 data rate ensures that memory-intensive applications such as database indexing, in-memory analytics, virtualization, and scientific simulations benefit from reduced memory bottlenecks.Within this category, DDR5-6400 RDIMMs are positioned for high-performance enterprise deployments where memory speed directly impacts application responsiveness and system throughput. The increased transfer rate supports multi-core processors with high thread counts, ensuring that each core has timely access to data without contention.

ECC Registered RDIMM Reliability and Data Integrity

ECC registered memory modules are a cornerstone of enterprise computing, and this category emphasizes data accuracy and fault prevention. Error Correcting Code (ECC) functionality allows the memory to detect and correct single-bit errors while identifying multi-bit errors. This capability is essential for environments where even minor data corruption could lead to system crashes, corrupted datasets, or incorrect computational results.The registered design further enhances reliability by buffering command and address signals. This architecture minimizes signal distortion and timing issues, especially in systems populated with multiple memory modules. Together, ECC and registered buffering provide a stable foundation for long-term, uninterrupted operation in mission-critical servers.

1Rx4 Memory Module

The 1Rx4 configuration refers to a single-rank module built using x4 DRAM components. This layout is commonly favored in enterprise servers due to its superior fault isolation and compatibility with advanced error correction schemes. Using x4 devices allows server platforms to implement chip-level error correction, enhancing resilience against DRAM component failures.This memory organization is particularly advantageous in large-scale deployments where uptime and data integrity are paramount. The x4 architecture supports advanced RAS (Reliability, Availability, and Serviceability) features commonly found in enterprise-grade CPUs and chipsets.

Latency CL52 and Timing

CAS latency plays a critical role in determining how quickly memory can respond to access requests. With a CL52 timing specification, this DDR5 RDIMM balances high frequency operation with stable latency characteristics. While higher frequencies naturally result in increased latency values, the overall effective latency remains competitive due to the significantly faster data transfer rates.In enterprise workloads, consistent and predictable latency is often more important than raw timing numbers. This category prioritizes steady performance under load, ensuring that applications experience minimal jitter and reliable response times even during peak usage periods.

Power Efficiency and 1.1V Operating Voltage

DDR5 technology introduces significant advancements in power efficiency, and this category highlights the advantages of a reduced 1.1V operating voltage. Lower voltage operation translates to reduced power consumption and heat generation, which is especially important in dense server environments where energy efficiency directly impacts operational costs.In addition to lower voltage, DDR5 RDIMMs incorporate on-module power management features that improve voltage regulation and stability. This design reduces noise and improves signal integrity, contributing to overall system reliability and longevity.

288-Pin RDIMM Form Factor and Platform Compatibility

The 288-pin RDIMM form factor is the standard for modern DDR5 server memory modules. This category ensures mechanical and electrical compatibility with next-generation server motherboards and processor platforms. The pin layout supports enhanced signaling requirements and increased data rates, enabling reliable communication between the memory module and the memory controller.Registered DDR5 modules are designed exclusively for server and workstation platforms that support RDIMM memory. They are not interchangeable with unbuffered DIMMs, underscoring the importance of selecting memory that aligns with system architecture requirements.

Scalability Advantages in Multi-Socket Systems

DDR5 ECC Registered RDIMMs are designed to scale efficiently in multi-socket server systems. The registered architecture reduces electrical load, enabling systems to support higher memory capacities without compromising signal integrity. This scalability is critical for enterprise workloads that require expansive memory footprints.

Comparisons with DDR4 Modules

Compared to DDR4, the MTC20F1045S1RC64BH1 DDR5 module offers higher bandwidth, improved power efficiency, and enhanced memory reliability. DDR5 modules support larger capacities per stick, more sophisticated ECC integration, and better handling of simultaneous data streams. Users upgrading from DDR4 can expect measurable improvements in multitasking, application load times, and system responsiveness. In server deployments, DDR5’s higher data rate and on-die ECC result in greater uptime and reduced risk of data corruption compared to legacy DDR4 modules.
