The Supermicro MEM-DR516L-SL02-ER48 16GB DDR5 4800MHz PC5-38400 RDIMM memory module represents a highly specialized category of enterprise-grade DDR5 server memory engineered to meet the growing performance, reliability, and scalability needs of modern data centers and enterprise computing environments. This category focuses on mid-range capacity DDR5 RDIMM modules designed to balance cost-efficiency, performance, and error-correction reliability. With a standard 16GB capacity per module, the MEM-DR516L-SL02-ER48 modules are particularly well-suited for virtualization, cloud computing, mid-tier enterprise applications, web servers, and other mission-critical workloads that require fast memory access, consistent latency, and high operational reliability.

DDR5 4800MHz Performance and Bandwidth Enhancements

Operating at a speed of 4800MHz, the MEM-DR516L-SL02-ER48 memory modules provide significant bandwidth improvements compared to legacy DDR4 solutions. The PC5-38400 bandwidth rating allows for rapid data transfer between the CPU and memory subsystem, which is critical for latency-sensitive applications and high-throughput enterprise workloads. Servers equipped with these DDR5 modules can handle multiple concurrent processes efficiently, ensuring stable performance across virtualization clusters, database servers, and cloud computing nodes.

16GB Capacity for Flexible Server Configurations

The 16GB capacity per module in this category offers a practical balance between memory scalability and cost-effectiveness. It is ideal for mid-tier enterprise servers, application servers, virtualization nodes, and web hosting servers that require moderate to high memory throughput but do not need extremely high-capacity modules. By using multiple 16GB modules across available DIMM slots, IT administrators can scale memory capacity efficiently without overpopulating memory channels or compromising signal integrity. Enterprises can also standardize server memory deployments using this category, which simplifies maintenance, reduces configuration errors, and ensures consistent performance across multiple server nodes.

Registered DIMM (RDIMM) Reliability

The MEM-DR516L-SL02-ER48 memory modules utilize registered DIMM architecture, which improves stability and signal integrity by placing a register between the memory controller and the DRAM chips. This architecture is critical for enterprise servers with high memory density, multi-socket configurations, or workloads requiring sustained performance over long periods. RDIMM design allows for increased memory population while reducing the risk of errors caused by electrical interference or signal degradation. By employing RDIMM technology, this memory category ensures consistent performance across all supported DIMM slots, which is crucial for mission-critical servers used in virtualization, database operations, and cloud infrastructure.

ECC and Data Integrity

While the MEM-DR516L-SL02-ER48 does not explicitly state ECC in its standard model name, many RDIMM DDR5 server memory modules incorporate on-die ECC or are compatible with ECC-enabled server configurations. ECC (Error-Correcting Code) provides automatic detection and correction of single-bit errors, reducing the risk of data corruption, system crashes, and downtime in enterprise workloads. This feature is critical for applications that require high reliability, including financial transaction servers, cloud computing nodes, virtualized environments, and database servers where uptime and data integrity are paramount.

1Rx8 Single-Rank Memory Organization

The MEM-DR516L-SL02-ER48 modules utilize a 1Rx8 single-rank architecture, where each module contains a single rank of x8 DRAM chips. Single-rank modules typically provide more predictable memory access times and improved channel efficiency in servers with multiple populated DIMM slots. This memory organization allows IT administrators to deploy higher memory densities without compromising memory channel performance or introducing latency penalties associated with dual-rank modules. 1Rx8 configuration also enhances compatibility across a wide range of server motherboards and chipsets, ensuring that these modules can be deployed consistently in multi-node enterprise environments.

288-Pin DDR5 Form Factor

The MEM-DR516L-SL02-ER48 modules adhere to the 288-pin DDR5 standard form factor, ensuring compatibility with contemporary server motherboards designed for DDR5 memory. Standardization of the 288-pin layout allows these modules to be integrated seamlessly into a variety of enterprise servers without concerns about physical or electrical incompatibilities. The standard form factor also supports high-speed signaling and efficient power delivery, ensuring that memory performance remains stable across fully populated server configurations. Compatibility with the standard DDR5 RDIMM form factor allows IT administrators to deploy the MEM-DR516L-SL02-ER48 across multiple servers, simplifying inventory management and reducing deployment complexity.
