High-Capacity 128GB RDIMM Architecture

Modules in this category are defined by their 128GB RDIMM configuration, a feature that provides exceptional memory density for modern enterprise servers. High-capacity modules reduce the total number of DIMMs required to reach substantial memory capacity, allowing system architects to implement dense memory configurations while minimizing motherboard slot usage. The Supermicro MEM-DR512MH-ER48, with its 128GB capacity, supports memory-intensive workloads, including virtualization, database servers, large-scale in-memory computing, and analytics platforms.

4Rx4 Memory Rank Configuration

The 4Rx4 rank architecture of these modules is another defining feature that enhances both memory capacity and performance. With four ranks of DRAM chips organized in x4 configuration, this memory type allows for rank interleaving, a technique that enables the memory controller to access multiple ranks simultaneously, improving effective bandwidth and reducing latency. The x4 organization also facilitates robust ECC error detection and correction, ensuring that critical enterprise applications remain reliable and error-free during operation.

DDR5-4800MHz Frequency and Performance

Operating at 4800MHz, this category provides a balance between high bandwidth and energy efficiency. The DDR5-4800MHz frequency ensures compatibility with a wide range of enterprise server platforms while delivering high-speed data transfers and low latency. The Supermicro MEM-DR512MH-ER48 takes advantage of DDR5 dual subchannel architecture, which splits each module into two independent 32-bit subchannels. This allows for improved parallelism and more efficient data handling, ensuring that servers can maintain peak performance even under heavy workloads.

PC5-38400 Bandwidth and Data Throughput

The PC5-38400 designation of this memory module indicates a theoretical maximum data bandwidth of 38.4GB/s per module. In multi-channel memory configurations, the total system bandwidth increases significantly, supporting data-intensive workloads that rely on rapid access to large datasets. The Supermicro MEM-DR512MH-ER48 ensures that CPUs can receive data quickly and efficiently, reducing bottlenecks and improving overall server performance in enterprise applications.
