Samsung M393A2G40DB0-CPB 16GB DDR4-2133MHz RDIMM 2Rx4 CL15 Memory

Product Description

The Samsung M393A2G40DB0-CPB is a high-capacity 16GB DDR4 Registered DIMM (RDIMM) memory module, specifically designed for server and enterprise-level computing environments. It operates at a speed of 2133MHz, offering a substantial increase in bandwidth and performance compared to previous DDR generations. The PC4-17000 designation signifies its data transfer rate, ensuring compatibility with modern server platforms that require high-speed memory solutions for demanding workloads. This module features a CAS Latency (CL) of 15, which is a standard latency for DDR4 memory at this speed, providing efficient access times for data retrieval. The 2Rx4 configuration indicates a dual-rank design, where each rank is composed of x4 (4-bit wide) DRAM chips. Dual-rank modules can offer performance advantages in certain server architectures by allowing the memory controller to access different ranks concurrently, thereby increasing overall memory throughput and efficiency. As a Registered DIMM (RDIMM) with ECC (Error-Correcting Code) capabilities, the M393A2G40DB0-CPB is built for enhanced system stability and data integrity. RDIMMs incorporate a register chip that buffers command and address signals, reducing the electrical load on the memory controller and enabling higher memory densities and configurations. ECC functionality is critical in server environments as it can detect and correct memory errors, preventing data corruption and system crashes. This makes the module an essential component for mission-critical applications and data-intensive tasks.
