Description
The Dell A21327993 is a high-quality 4GB Registered Dual In-line Memory Module (RDIMM) specifically engineered for deployment in Dell server and workstation environments. This module utilizes DDR3 SDRAM technology, offering a significant performance upgrade over previous generations. With a clock speed of 1333MHz, it provides ample bandwidth for demanding enterprise applications, virtualization, and data processing tasks. The 2Rx4 configuration indicates that the memory chip is organized into two ranks, each with four data lines per chip. This dual-rank design can offer improved performance in certain server workloads by allowing the memory controller to access data from different ranks concurrently. The Registered (RDIMM) nature of this module means it incorporates a register chip that buffers command and address signals, reducing the electrical load on the memory controller. This is crucial for systems that utilize a large number of memory modules, enhancing stability and allowing for higher memory capacities. Featuring a CAS Latency (CL) of 9, this memory module strikes a balance between speed and timing precision. The CL9 rating signifies that it takes 9 clock cycles for the memory module to respond to a column address strobe command. This module is also ECC (Error-Correcting Code) Registered, providing enhanced data integrity by detecting and correcting single-bit errors, which is vital for mission-critical server operations. It operates at a standard voltage of 1.5V and is designed to be compatible with Dell systems that support DDR3 1333MHz RDIMMs.
