The Supermicro MEM-DR516L-SL02-ER48 16GB DDR5 4800MHz PC5-38400 RDIMM memory module is a high-performance, enterprise-grade memory solution designed for modern server architectures. This category of memory modules represents a convergence of speed, reliability, and energy efficiency, tailored specifically for data centers, virtualization environments, cloud computing, and mission-critical enterprise servers. The MEM-DR516L-SL02-ER48 module leverages DDR5 technology, delivering faster data transfer rates, improved bandwidth, and enhanced power management features compared to DDR4, while providing a standardized 16GB capacity that balances cost-efficiency with performance requirements.

DDR5 4800MHz Performance and Advanced Bandwidth

Operating at 4800MHz, the MEM-DR516L-SL02-ER48 modules deliver substantial performance improvements over previous DDR4 memory generations. The PC5-38400 bandwidth rating allows for rapid data transfers between the CPU and memory subsystem, reducing latency and enabling efficient handling of multi-threaded applications. High-speed DDR5 memory is particularly beneficial for virtualization servers, cloud computing platforms, database servers, and mid-tier enterprise applications where consistent, high-throughput memory access is critical. The 4800MHz data rate ensures that memory-intensive workloads can execute smoothly and efficiently, even when multiple virtual machines or applications are running concurrently on the same server.

16GB Capacity for Enterprise Scalability

Each MEM-DR516L-SL02-ER48 module offers a 16GB capacity, which provides a practical balance between performance, scalability, and cost. 16GB modules are suitable for mid-tier enterprise servers, web servers, application servers, and virtualization nodes that do not require extremely high-capacity DIMMs. Using multiple 16GB modules across a server’s DIMM slots allows administrators to scale memory capacity efficiently without overloading channels or compromising memory stability. The modularity of this category makes it easier to standardize server configurations across large fleets, simplifying deployment, management, and maintenance.

Registered DIMM (RDIMM) Architecture for Stability

The MEM-DR516L-SL02-ER48 modules utilize a Registered DIMM (RDIMM) design, which places a register between the memory controller and DRAM chips. This architecture significantly improves signal integrity, enabling servers to support higher memory densities and multiple memory channels without compromising stability. RDIMM technology is a standard in enterprise-grade servers, providing the necessary reliability for continuous operation under demanding workloads. It is particularly important in multi-socket servers where the electrical load on the memory bus can be substantial, as RDIMM design reduces the likelihood of signal degradation and ensures consistent performance across all populated DIMM slots.

1Rx8 Single-Rank Memory Configuration

The MEM-DR516L-SL02-ER48 modules use a 1Rx8 single-rank organization, distributing memory across a single rank of x8 DRAM chips. Single-rank modules provide efficient memory access with predictable latency, especially in multi-DIMM configurations. The 1Rx8 design enhances compatibility across various server motherboards and chipsets, allowing for flexible deployment across mid-tier enterprise servers. This organization supports optimal memory interleaving, which improves throughput in virtualization clusters, web server farms, and containerized application environments.

288-Pin DDR5 Form Factor

The MEM-DR516L-SL02-ER48 modules conform to the 288-pin DDR5 standard form factor, ensuring compatibility with a broad range of server motherboards supporting DDR5 RDIMM memory. The standardized form factor facilitates high-speed signaling, reliable power delivery, and efficient thermal dissipation, making these modules suitable for densely populated server configurations. IT administrators benefit from the predictability and consistency offered by standardized modules, which reduces configuration errors, simplifies deployment, and enables uniform performance across a server fleet.
