Samsung M393A1K43BB1-CTD7Y 8GB DDR4-2666MHz RDIMM 1Rx8 CL19 Memory

Description

This Samsung memory module, identified by SKU M393A1K43BB1-CTD7Y, is an 8GB DDR4 Registered DIMM (RDIMM). It is designed for modern server and workstation platforms that benefit from the increased performance, efficiency, and bandwidth offered by DDR4 technology. Operating at a higher frequency of 2666MHz (PC4-2666V), this module provides faster data transfer rates compared to lower-speed DDR4 modules, making it suitable for demanding applications. The RDIMM form factor includes a register that buffers command and address signals, reducing the load on the memory controller and enabling greater system stability and higher memory capacities. The module features a 1Rx8 configuration, meaning it is single-ranked with each rank comprising x8 DRAM chips. While single-rank modules may not offer the same rank interleaving benefits as dual-rank modules in all scenarios, they are often optimized for specific performance characteristics and power efficiency. The CAS latency is CL19, which is typical for DDR4 memory at this speed, representing a balance between rapid data access and overall system responsiveness. The standard operating voltage for DDR4 is 1.2V, contributing to lower power consumption and heat generation compared to older DDR generations. As a component intended for enterprise use, the M393A1K43BB1-CTD7Y incorporates Registered ECC (Error-Correcting Code). ECC memory is critical in server environments for its ability to detect and correct memory errors, thereby ensuring data integrity and preventing system crashes. This 8GB DDR4 RDIMM is a reliable choice for upgrading existing systems or for new server builds where a balance of capacity, speed, and data integrity is required.
