Product Description
The Dell A3698656 is a 4GB Registered DIMM (RDIMM) module utilizing DDR3 SDRAM technology, operating at a speed of 1333MHz (PC3-10600). RDIMMs are characterized by an onboard register chip that buffers address and command signals between the memory controller and the DRAM chips. This buffering reduces the electrical load on the memory controller, enabling systems to support a larger number of memory modules and higher overall memory capacities, which is a critical requirement for many enterprise servers and high-performance workstations. This particular module features a 2Rx4 configuration. '2R' denotes dual-rank, meaning the module has two independent sets of memory chips (ranks) that the memory controller can access. 'x4' indicates that each DRAM chip on the module has a data width of 4 bits. Dual-rank modules can sometimes offer performance advantages through rank interleaving, where the controller alternates accesses between ranks, potentially improving throughput. The CAS Latency (CL) is rated at 9, specifying the delay in clock cycles from the time the memory controller commands the module to access a particular column until the data is available. Designed for compatibility with Dell systems that specify DDR3 RDIMMs, this 4GB module is suitable for upgrading memory in servers handling demanding workloads such as virtualization, large databases, or complex scientific simulations. The RDIMM architecture ensures greater stability and reliability for memory-intensive operations, making the A3698656 a valuable component for enterprise environments.
