Samsung Enterprise Memory Manufacturing Standards

This memory category benefits from Samsung’s vertically integrated semiconductor manufacturing process, which ensures precise quality control from silicon fabrication to final module assembly. Samsung’s enterprise DDR4 RDIMM products are manufactured using rigorously tested DRAM ICs that conform to JEDEC standards, ensuring compatibility across a wide range of server platforms from leading OEMs. The M393A4K40BB0-CPB module reflects this category’s emphasis on long-term availability, firmware consistency, and predictable lifecycle management.

DDR4 2133MT/s Performance Profile and PC4-17000 Bandwidth

The DDR4 2133MT/s speed grade defines a foundational performance tier within the DDR4 server memory category. Operating at an effective data rate of 2133 megatransfers per second, this memory class provides PC4-17000 bandwidth, enabling efficient data movement between CPU and memory subsystems. While newer DDR4 and DDR5 speeds exist, this category remains relevant for platforms optimized around stability, compatibility, and predictable latency characteristics.

Latency Characteristics and Real-World Workloads

CAS latency plays a crucial role in determining how quickly memory responds to access requests. Within this category, CL15 represents a carefully tuned balance between speed and reliability. Enterprise workloads such as transactional databases, ERP systems, and virtual desktop infrastructure benefit from stable latency behavior rather than aggressive timing profiles. The Samsung M393A4K40BB0-CPB aligns with this category’s design philosophy by maintaining consistent access times under heavy multi-threaded load.

ECC Registered Memory and Data Integrity Assurance

Error Correcting Code functionality is a defining feature of this memory category. ECC Registered DDR4 modules like the Samsung M393A4K40BB0-CPB are engineered to detect and correct single-bit memory errors while identifying multi-bit errors. This capability is essential in environments where data corruption can lead to system crashes, incorrect computations, or compromised data integrity. ECC protection is particularly critical for servers running financial applications, healthcare systems, scientific simulations, and enterprise databases.

Registered DIMM Signal Stability Advantages

The registered design employed in this category places a register between the memory controller and the DRAM chips, effectively buffering address and command signals. This architecture reduces electrical load on the memory controller, allowing servers to support higher memory capacities and more populated DIMM configurations. The Samsung M393A4K40BB0-CPB exemplifies this category’s ability to maintain signal integrity across densely populated memory channels.

32GB Capacity for Scalable Server Deployments

The 32GB capacity segment within this memory category offers an optimal balance between density and cost-efficiency. By utilizing high-density DRAM chips, this category enables system builders to achieve substantial memory capacity using fewer DIMM slots. This approach improves airflow, reduces power consumption per gigabyte, and simplifies memory expansion strategies. Servers equipped with multiple 32GB DDR4 Registered ECC modules can reach total memory capacities suitable for demanding enterprise workloads without exceeding platform limitations.

Capacity Planning Use Cases

Virtualization platforms such as VMware ESXi, Microsoft Hyper-V, and KVM-based solutions benefit significantly from this memory category. The 32GB module capacity allows administrators to allocate sufficient memory to guest systems while maintaining overhead for hypervisor operations. This DDR4 2133 ECC Registered category supports consistent performance under memory overcommitment scenarios. Database servers and application servers also benefit from higher per-module capacity. By reducing the total number of DIMMs required, this category minimizes potential points of failure and simplifies maintenance.

288-Pin DDR4 RDIMM Form Factor

The 288-pin RDIMM form factor defines the physical and electrical interface for this memory category.
