Dell A21327986 8GB DDR3-1066MHz RDIMM 2Rx4 CL7 Memory

Product Description

The Dell A21327986 is an 8GB DDR3 Registered DIMM (RDIMM) memory module, specifically designed for server and workstation environments where data integrity and stability are paramount. As an RDIMM, it includes an onboard register that buffers command and address signals, reducing the electrical load on the memory controller. This allows for higher memory capacities and improved system stability, which are critical for mission-critical applications and dense server configurations. Operating at a speed of 1066MHz, this module provides a solid performance baseline for server tasks. The CAS Latency (CL) is rated at 7 clock cycles, indicating a relatively low latency for its speed class, which contributes to efficient data retrieval. The 2Rx4 rank configuration signifies that the module has two ranks, with each rank utilizing DRAM chips that are 4 bits wide. This configuration is common for server memory modules, balancing density and performance. Crucially, this module supports ECC (Error-Correcting Code) functionality. ECC memory can detect and correct common types of internal data corruption, significantly reducing the likelihood of errors that could lead to system crashes or data loss. This makes the Dell A21327986 an ideal choice for servers running critical applications, databases, or virtualized environments where reliability is non-negotiable. The Dell part number ensures compatibility with specific Dell server models.
