Description
The Dell A3866778 is a 4GB DDR3 Registered DIMM (RDIMM) memory module designed to enhance the performance and capacity of compatible Dell servers and workstations. Operating at a frequency of 1333MHz, it provides a significant boost for memory-intensive applications and multitasking environments. The 2Rx4 configuration indicates a dual-rank design with four data bits per chip, often leading to improved performance in certain server workloads. With a CAS Latency (CL) of 9, this module strikes a balance between speed and stability, ensuring efficient data retrieval. As an RDIMM, it incorporates a register chip that buffers command and address signals, reducing electrical load on the memory controller and allowing for higher memory capacities and improved signal integrity. This makes it an ideal choice for enterprise-grade systems where reliability and performance are paramount. The module adheres to standard DDR3 specifications, including a voltage requirement of 1.5V. Its ECC (Error-Correcting Code) capability helps detect and correct single-bit memory errors, further enhancing system stability and data integrity, which is crucial for mission-critical applications and continuous operation environments.
