Dell A21346870 4GB DDR3-1333MHz RDIMM 2Rx4 CL9 Memory

Product Description

The Dell A21346870 is a 4GB DDR3 Synchronous Dynamic Random-Access Memory (SDRAM) module engineered for use in Dell server and workstation environments. Operating at a frequency of 1333MHz, this module provides a significant boost in data transfer rates compared to lower-speed memory, which is crucial for optimizing the performance of demanding enterprise applications. The Registered DIMM (RDIMM) form factor incorporates an onboard register chip that buffers command and address signals, reducing the electrical load on the memory controller and enabling greater memory capacity and stability within the system. This particular module features a 2Rx4 configuration, meaning it consists of two ranks, with each rank utilizing x4 (4-bit) DRAM chips. This dual-rank design can enhance performance by allowing the memory controller to access data from different ranks in an interleaved fashion, potentially improving throughput. The CAS Latency (CL) of 9 clock cycles indicates the delay between the memory controller issuing a column-read command and the data becoming available on the module's output pins. A CL9 rating at 1333MHz is a standard specification for performance-oriented DDR3 memory. Designed and validated for compatibility with a range of Dell server and workstation models, the A21346870 ensures seamless integration and reliable operation. It is an ideal component for upgrading existing systems or configuring new ones that require increased memory capacity and bandwidth to support virtualization, database management, scientific computing, and other memory-intensive workloads. By providing faster and more abundant memory resources, this module contributes to improved system responsiveness and overall productivity.
